1 FOREWORDThis document shows the way to access or create a drawing file (�CatDrawing�) and documentationexisting thereof.

When a �CatDrawing� is created, it is empty and it will received information from space files (V4models, �CatParts�, �CatProducts�, etc.). Both files, space and drawing, will be necessarily y open inorder to transmit information from one to the other.

Drawing tools (Catia V5 drawing module) will permit us to obtain:• Projected geometry of solids to document, that is, the necessary to views for a geometric

definition.• Dimension these views• Creation of every type of texts and notes.• Include drawing detail so they are created in the model as if they are obtained from a library.• Paper print of �CatDrawings�, that is, release of plotters.

2 CREATE OR OPE N A DRAWING FILEA drawing file will be named �CatDrawing�. It can be done using four different ways:

• �Start� Menu: create a new file.• �File� Menu: accessing to an existing one and two different ways to create a new one.• �Workbench� toolbar: create a new file.• �Standard� toolbar: create a new file.

Whenever a new �CatDrawing� is created, it shall be done with a new single drawing sheet (paper�CatDrawing� representation). In these cases, it will appear �New Drawing� window allowingdefinition of characteristics of the drawing sheet and also creation of it:

Details of the aforementioned items are as follows:

Sheet format

Sheet orientation

Scale of sheets

�CatDrawing�Creation



“Start” Menu

Once space file is open and active, this option will offer the possibility of creating a drawing file eitherempty or with several space views.

“File” Menu

�File� menu offers three possibilities in order to obtain a �CatDrawing�:

• �New� → creates a new file.• �New from� → creates a new file as a copy of other.• �Open� → opens an existing file.

Selecting �New� window option, it will appear a window with a list of files which can be created. Fromthis window, Select �Drawing� and click OK.

“Workbench” toolbar

�Workbench� toolbar shows an icon representing Catia module in which we are operating. �Drafting�icon will be as follows:

A new �CatDrawing� can be created as follows:

Possibility of creatingan empty sheet or withseveral views

Characteristics of adrawing sheet

Possibility ofmodifyingcharacteristics of adrawing sheet using�New Drawing�

Drawing file or �CatDrawing� creation.

Clicking OK, �NewDrawing� will appear,allowing to create a�CatDrawing�



“Standard” Toolbar

Selecting the following icon from �Standard� toolbar, it will appear the same window as in �File +New� option, therefore, the steps to follow to create a new �CatDrawing� will be the same as in thisoption.

3 CREATE NEW D RAWING SHEETSThere are two types of drawing sheets:

• �Detail Sheet� → used for creating drawing detail in �CatDrawing�For further information see paragraph 10.2.

• �Sheet� → representing views, dimensions, etc.

A single sheet will be created (�Sheet.1�) if a new �CatDrawing� is created. The following method willpermit to created different CatDrawings.

• A �CatDrawing� second sheet will appear automatically (�Sheet.2�). It should have thesame characteristics as the first sheet but it can be changed using the window displayedif “File + Page Setup” is selected:

• Select �workbench� active icon. It willappear a window with a list of�workbenches� to which it is possible tohave access ( This list can be modifiedusing �Tools + Customize + Start menu�).

• Select Drafting icon.• One or more windows will appear similar

to the previous cases, intended to define�CatDrawing�. Click OK onto them fortheir creation.

• Select desired icon from �Sheets�toolbar (Spreading first icon of�Drawing� bar.



4 TREE OF SPECIF ICATIONSThree levels of nodes appear in the tree of specifications of a �CatDrawing�:

Detail sheets will have a distinctive symbol in order to be different from the others. Furthermore,symbol of the views containing it, will be also different.

Tree will be activated or deactivated:• Hitting F3 key• Using �View + Specifications�

From the tree, it will be possible to manage the different views using the menu which is displayed ifright-clicking (it will be also displayed positioning over the view background). This menu can copyand paste views or delete and send views to �No show�, etc.

Page format

Page orientation

It is possible tomodify all sheet orjust active sheet.

It is possible toremove pagebackground.

• Main node representingdrawing file. It will have thesame name of the file.

• Nodes representing thedifferent sheets whichconstitute a �CatDrawing�

• Nodes representing the differentviews which constitute a drawingsheet. As a distinction, the activeview will be underlined in the tree.



5 CREATION OF D RAWING VIEWSIt will be possible to create views which have no relation with space and views which obtaingeometric information from space elements.

�New View� tool will be used to create view without relation with space, selecting icon from�Drawing� tool bar.

View in relation with space files will be those which contain projections of solids. They will becreated using tools of �Views� bar. Space file will be necessarily open in case of solid geometryprojection.

The following paragraphs describe process to create these views, that are:

• Main views (front, right and left).• Isometric views.• Auxiliary views.• Partial section and break views.• Section views.• Detail view.

5.1 MAIN VIEWS

The main views (front-rear, right-left, top-button) will be created following these general steps:

• First, creating front view.• From this view, the rest of the main views will be created.

�Projections� tool bar will be used, after spreading first icon in �Views� tool bar:

Front view: follow these steps:

• Select projection plane of the view from the space.

• Select icon from �Projections� toolbar (after spreading first icon in�Views� tool bar).



• Selecting the plane, it will appear a pre-view of projections and a dial in which it ispossible to manage plane for redefinition and orientation of the front view.

• Clicking free-space or sheet dial centre, the view is positioned.

Right/left and top/button: they will be created following these steps:

• Dragging mouse towards any of the sides of the front view, it will appear a pre-view of thenew view.

• Clicking onto the free space, it will be set.

5.2 ISOMETRIC VIEW S

These views are representations of solids in isometric perspective.

Tool to use for its creation will be located in �Projections� bar, appearing after spreading the first iconof �Views� bar:

Steps to follow for isometric view creation are:

• Select icon .• Select plane in the space.

It will show a pre-view with the same orientation as solid in the moment of projection.• Manage dial in order to modify orientation. This dial is the same as in paragraph 5.1.

(front view definition).• View will be set by clicking onto dial centre or onto a drawing free area.

Using right button menu, itis possible to define dialcharacteristics.

• Select icon from �Projections� toolbar (after spreading first icon in�Views� tool bar)



5.3 WIZARD CONFIG URATIONS

A group of main and isometric views can be easily created using �View Wizard�. Wizard chooses acombination of views (configuration) in order to create all of them definitely.

�Wizard� toolbar will be used:

Depending on �Wizard� toolbar selected, it will be possible to choose views to project:

The following steps are to be performed if the user chooses a determined combination. For othercases, the process is alike but omitting steps, in which �Wizard� combination is chosen.

• Select icon • �View Wizard� will be displayed, and it will be possible to choose the desired combination.• Click �Finish� from the window• From the space, select front plain.• Selecting plane, it will appear a preview of projections and a dial in which it is possible to

manage plane for redefinition and orientation of the front view.This dial is the same as in paragraph 5.1. � front view definition -

• Views will be positioned clicking a free space or in the centre of the dial of the sheet.

5.4 AUXILIARY VIEWS

Auxiliary views are projections of a solid by a plane that forms an angle with some of the main views(front/rear, right/left and top/bottom) in order to have a better visualisation of solid characteristics.

Tool to use can be found on �Projections� bar, spreading the first icon of �Views� bar:

Possibility to choose acombination of views Combination of views proposed

by the system



Definition of these views will be accomplished onto another existing one that has to be active.

Steps to follow for its creation will be:

• Select icon • Select view plane.

For this, select a point (where the auxiliary view will be indicated) and an edge of viewsalready existing (to give plane orientation).

• A place will be positioned, indicating auxiliary view on the drawing.• Click a free space on the sheet.

5.5 BREAK VIEWS

Starting from a complete view, �Break view� permits to select two tools which are used to remove apart of the view (break view).

→ It removes a part of the view that does not give information, in order to decreaselength.

→ A partial section is performed to the view in order to visualise an internalcharacteristic of the solid.

5.5.1 DECREASE OF VIEW LENGTH

• Select icon • Select an element of the view to indicate location of the first cut. Two green lines will

appear (Horizontal and vertical)• Select one of the green lines to define orientation of cut lines.• Indicate position of second line cut.

First point selected

Selection of edge toindicate planeorientation.



• Click onto a free area of the sheet to create break.

To eliminate break, that is, to recover original view, select �Unbreak� option from the menu whichappears after right-clicking.

1st cut line

2nd cut line

5.5.2 PARTIAL SECTION OF VIEW

• Select icon • Draw a polygon of cut in the view. It will appear a window in which is possible to visualise

the solid and two green planes.The first plane is for part cut and on this, the drawn polygon in the view will be projected.

• Position cut plane on the desired location. It will be possible to select elements from otherviews to position this plane.

• Click OK.

In this case, this elementis selected to place theplane.

Polygon



To eliminate break, that is, to recover original view, select �Remove Breakout� option from the menuwhich appears after right-clicking.

5.6 SECTIONS

Section views are views sketching the solid cut in one o more planes so that it will be possible tovisualise inside the holes of the part.

The following are the different section types:

→ Offset section view: It sketches section or crossed cut together with the portion of thepart that remains behind.

→ Offset cut view: It sketches just the crossed cut.

→ Aligned section view: section planes are sketched in aligned position.

→Aligned section cut: section planes are sketched in aligned position.

Section will take place on the active view.

The last two types of sections are not used, therefore, this paragraph will not describe the process ofcreation.

Steps to follow for section view creation are:• Select the corresponding icon.

Cut plane



• Select the necessary holes and points in the drawing view to define cut profile. If it is

necessary to modify profile use .It is also possible to create a section or cut selecting a flat surface or a 3D drawing.Section plane appears in 3D part and it moves dynamically onto it.• Double-clicking to complete profile definition.

To change crossed of the section, place cursor onto it and select �Properties� using right button, orfrom toolbar �Graphic Properties� to choose a different one.

See paragraph 5.7.6. to modify definition of views.

5.7 DETAIL VIEW

These view are performed to visualise a detail of the view with a lower scale.

This can be carried out following two different methods:• Creation of a new view containing a portion of a different one with lower scale.• Clipping of a view to visualise a detail with a higher scale.

Toolbar to use in each case will be:

Detail views fromanother view.

Clipping of a view



5.7.1 DETAIL VIEW FROM ANOTHER VIEW

They will be new views containing a portion of another with a higher scale.

Toolbar to use will be �Detail�, after spreading the third icon of �Views� bar:

Detail will have obligatorily geometry of the active view.

Tool to use will be:

→ detail contained into a circle (whole circumference does not appear in detail view)

→ detail contained in a closed profile (whole profile does not appear in detail view)

→ detail contained into a circle

→ detail contained in a closed profile

The following steps should be carried out to create a detail view:• Select the corresponding icon.• Depending on the case, either introduce centre and radius of circle, or profile enclosing

detail.• Drag cursor to position detail and click to generate the view.

Scale modification can be carried out using �Properties� window , menu displayed after right buttonclicking or using �Edit� menu.

If a view is deleted, it does not delete details because they are starting identical views thoughclipped and with a different scale.



5.7.2 CLIPPING A VIEW WITH HIGHER SCALE

This type of views is generated clipping a view in order to visualise a portion with a higher scale.

�Clippings� toolbar will be used, spreading the fourth icon of bar �Views�:

→ view will be clipped by a circle

→ view will be clipped by a polygon sketched with cursor digitalisation onthe view.

In both cases steps to follow will be:• Select corresponding icon.• Depending on the case, either introduce centre and radius of circle, or profile enclosing

detail.• Drag cursor to position detail and click to generate the view.

Scale modification can be carried out using �Properties� window , menu displayed after right buttonclicking or using �Edit� menu.

Choose �UnClip� option to restore the complete view using menu after clicking with B3 at the edgeof the view.

5.8 MANAGING AND MODIFYING VIEWS

This paragraph detail the process to follow to manage views and to modify characteristics, propertiesand location.

Furthermore, it describes links that drawing file keeps with files of space and also updating if theydisappear.

5.8.1 ACTIVATE VIEW

An active view is underlined in the tree.

A view can be activated using several methods:• Double-clicking its name on the tree.• Double-clicking onto some element of the view.• Using right button, click onto its background selecting �Activate view� option



5.8.2 VIEW PROPERTIES

From �Properties� window it is possible to set some characteristics of the views. This window isdisplayed selecting �Properties�, from �Edit� menu or using menu after right-clicking.

From �Properties� window, it is possible to access to graphic characteristics regarding indications ofdetail views, section or break.

5.8.3 MODIFICATION OF PART SITE OR NAME

Drawing views keep a link with space geometry from which they were projected.

These links can be analysed and reset in case they had been detached. Process to carry out will beas follows:

• Select �Edit + Links� option.A �Links of the document CatDrawing� window will displayed in which is possible to access tothese links:

View Name

Scale andangle

Dressup

Block view

Backgroundremoval



• Opening CatDrawing, if space file has changed name or location, it will display a window,offering the possibility of resetting new links clicking �Edit/Links�. Besides, tree aspect willbe as follows:

• Another window will be displayed and clicking �Find� it will be possible to introduce thenew location and new space file name. Clicking OK, new links will be created.

Location ofspace file

Possibilityof openingspace file



5.8.4 TRANSLATION OF A V IEW INSIDE A SHEET

Follow these steps:

• Hit and hold down mouse left button onto the edge of the view to move.• Mouse is moved to the new location of the view.

Aligning views:

Views creation is automatic. To removed a forced aligning, right-click onto the edge of the view orfrom the tree , and select �Do not align views� of the displayed menu.

Use the same method and select �Align Views� option to force aligning.

5.8.5 MOVE VIEWS FROM ONE SHEET INTO ANOTHER

It is possible to move a view from a sheet into another, even if they belong or not to the sameCatDrawing.

Process to follow will be:• Select the view to copy/cut• Select �Copy� or �Cut� option. This selection can be carried out either using �Standard�

toolbar icons or with the menu displayed after right-clicking.• From the tree, select drawing sheet where the view will be located and choose �Paste�

option.

Sheet that has received the view will not be updated.

Name of the new view will show creation order issue.

5.8.6 MODIFICATION OF SECTIONS AND DETAILS

It is possible to modify section views and detail views using the following icons:

→ reverses cut direction (section views)

→ replaces a cut profile for another

Steps to follow for modifications will be:

• Double clicking onto detail or section view indication, it will appear a new bar of icons(�Edit/Replace�)

• Select one of the two previous icons.In case of cut profile substitution, a new one will be drawn.

• Click exit icon



6 CREATION OF GEOMETRY OF REFERENCEIt will be included in the next edition.

7 DIMENSIONING. TOLERANCESThis chapter details the process to follow to dimension drawing views and to indicate dimensiontolerances as well as geometric.

Therefore, it will define what characteristics can be set and execution.

Furthermore, it details process to follow for managing and modifying dimensions.

7.1 CREATION OF AUTOMATIC DIMENSIONS

Dimension automatic generation tools will not be used for dimensioning views. Therefore, thisparagraph will describe generically how every single tool works but without focussing on the creationprocess.

Automatic creation of dimensions will be performed using �Generation� bar tool.

Drawing dimensions are generated in a single step. The most representative views are dimensioned.They offer us the possibility of performing a visual analysis of �constraints� (in the space) anddrawing dimensions.

There is another tool in �Generation� bar similar to the aforementioned, but with the possibility ofmanaging dimension generation time. Icon of this tool will be as follows:

7.2 MANUAL CREAT ION OF DIMENSIONS

This paragraph will define:

• Tooling bar used for manual creation of dimensions.• Dimension types and steps .• Characteristics of dimensions which can be defined during the process of creation.



7.2.1 TOOL BAR

Manual creation of dimensions is performed using �Dimensions� toolbar (after spreading first icon of�Dimensioning� bar).

7.2.2 TYPES OF DIMENSIONS AND STEPS TO FOLLOW

Steps to follow for creating dimensions will be:

• Select icon form �Dimensions� toolbar• Select geometric elements to dimension. A preview of the dimension will appear.• If desired, choose dimension characteristics appearing in the spreading menu of mouse

B3 (see paragraph 7.2.3).• Click a free space on the sheet.

The selection of icons and elements and the possible dimension types are shown in the followingtable:

(*) Representation and dimensioned values for chamfer depends on the order of choosing the 3constituting lines). They will be the following:

• First element selected: It marks orientation of dimension and this will be perpendicular tothe first element selected.

• Second element selected: dimension will show always two values. The first onecorresponds to chamfer projection length in the direction of the second element selected.



• Third element selected: second dimension value will be the chamfer projection length inthe direction marked by the third element selected.

7.2.3 DEFINITION OF CHAR ACTERISTICS OF DIMENSIONS DURING CREATIONPROCESS

During the process of dimension creation, it is possible to define some characteristics right-clickingonto them. Some of these characteristics are:

(a) �Dimension Type� (ex.: length, distance, radius, etc.)(b) �Dimension Representation� (ex.: vertical and horizontal orientation, etc.) . Corresponding

to �Tools� icons.(c) �Value Orientation� (ex.: vertical and horizontal orientation, etc.)(d) �Angle Sector�.(e) �Extension Lines Anchor� in case of distance type dimensions(f) �Add Funnels�. It expands the space between dimension lines for a better visualisation of

dimension value.

Dimension line movement and dimension value displacement will be carried out quickly followingthese steps:

• Select line or dimension value, as applicable.• Drag mouse (holding down) to the desired position.• Click a free space on the sheet.

Dimension value will be back to the original position if the option �Restore Value Position� is selectedusing mouse right button menu.



Dimension lines will be lengthened following these steps:

• Select dimension. Orange points on the line edges will appear.• Select one of the point and drag (holding down) up to obtain the desired length of

dimension line (repeat this step with all desired points)• Click a free space on the sheet.

7.5.2 DIMENSION GROUP ARRANGED LOCATION

Consecutive dimensions performed with icon are automatically ordered upon parametersestablished in �Tools + Options + Dimension + Line-Up.�

But if they are created with other tools, dimensions are located irregularly. For a fast arrange use�Line-Up� option, which can found in:

• Tools+Positioning+Line-Up

• Directly in icon of toolbar �Positioning�• Selecting dimensions and spreading mouse B3 menu.

Steps to follow for their location are:• Select dimensions.• Select �Line-Up� option• Select a point or reference element from which dimension separation distances are count.

�Line-Up� window will appear.• Introduce dimension separation parameters and click OK. Dimension will be ordered

automatically.



7.5.3 INSERT TEXT BEFORE OR AFTER DIMENSION VALUE

It will be possible to insert texts before or after dimension value. These steps will be followed:• Select dimension. Two red triangles will appear, one before and the other after dimension

value.• Select one of the triangles. A window will be displayed in which text is inserted. Example,

if before is selected � Insert Text Before� will be displayed.• Type text and click OK. Text will automatically display.

It is also possible to introduce texts using �Properties� window ( �Edit� menu or mouse right button),in �Dimension Texts� tab.

7.6 CREATING AND MODIFYING “DATUM FEATURES” ANDGEOMETRIC TOLERANCES

8.7 MODIFY AND MANAGE ANNOTATIONS AND TEXTS

This paragraph details modifications which can be performed to annotations, as well asmanagement.

Double-clicking onto annotations and texts, it will be possible to redefine all the characteristics setduring the creation process.

8.7.1 ASSOCIATE AND ISOLATE POSITION FROM A TEXT TO AN ELEMENT

Once text has been created, its position can be associated or isolated to the position of an drawingelement as follows:

• Select text• Select �Positional Link� option using mouse right button.• Select �Create� if it is required to create position link and element to associate. Select

�Delete� if it is required to released its position.

• Select icon from �Symbol� toolbar(spreading second icon of�Annotations� bar).



8.7.2 ASSOCIATE AND ISOLATE A TEXT TO A DIMENSION OF A SOLID

A text can be associated to a geometric dimension value of a CatPart. Therefore, text edition showsdimension value and whenever this value changes, text also changes.

Steps to follow to set this link are:

• Select �Attribute Link� option, using mouse right button,, during text creation process ormanaging the text once it has been created.

• Select �feature� of CatPart to which it will be associated. Selection will be carried outfrom the tree or directly in the solid.�Attribute Link Panel� will be displayed with a list of geometric attributes of the selectedfeature and value for all of them.

• Select desired attribute and click �OK�. �Text Editor� window will show attribute value.In this window, it will be possible to insert any text (ex.: �D =�), and click �OK� onto it.A text can be related to an attribute or more, selecting them successively in the window.

Select in the solid or fromthe tree.



Select text in order to isolate it from a solid geometric attribute value and using mouse right buttonclick �Isolate Text� option.

If it is required to have several texts associated to the same type of geometric dimension of asolid (example: diameters of different holes), it is possible to copy the link of a text previouslycreated. Steps to follow are:

• Select �feature� from CatPart, (ex.: select Hole 4)If more than a CatPart are open and all have a �feature selected�, it will appear the value ofall of them in text edit.

• Select text associated to the attribute and position created text.

8.7.3 LOCATION OF “LINKS” IN A TEXT

A text can have two types of �links�:• Text position linked to position of other element.• Text edition linked to CatPart dimension value (geometric attribute).

• Select icon located �Text� toolbar(after spreading first icon of�Annotations� toolbar).



Select text and select �Query object links�� option (after spreading menu using mouse right button)�Query Link Panel� window will be displayed. Here appears a list of text links and their features.

• Select icon �Rotation Definition� window will bedisplayedDeactivate �Duplicate mode� option

• Define rotation centre and initial andfinal points of rotation arcThey can also be defined from�Tools� toolbar

8.7.6 SEARCH AND REPLACE TEXT

There are tools for searching and subsequently replacing texts in a drawing. They can be selectedas follows:

• �Edit + Find� and selecting �Replace� key will display the same window of the following tool.• �Edit + Replace�



Steps to follow for searching and replacing texts are:

• Select one of the two tools. Depending on the case the following windows will be displayed:

Match case → distinguishes between capital or smallFind whole words only → searches forRe-frame the window → performs a zoom of the text

• Type in each case texts which are to be found or replaced.

9 PLOTTERS RELE ASEPlotters released will be carried out using �Edit + Print� option.

Define print parameters from �Print� window. It is possible to distinguish six action fields:



1: Printer/plotter properties, ex.: roll size, exit sheet size, etc.2: Print range:

�All sheets� → print all sheets of the drawing�Current sheet� → print current sheet�Sheets� → print a selection of sheets�Current display� → print a display of drawing window

3: Copies: number and exit order4: Choose paper fitting choice:

�Best orientation� → orientates considering drawing dimensions�Fit to printer format� → keeps printer paper format.�Clip to the sheet format� → keeps format of the drawing sheet.

5: Others options: ex.: printing colour, etc.6: It is activated with �Current display� option. It provides image scale and its position in theplotter. �Fit in Page� option fits drawing considering sheet size.

It is advisable, prior to release a plotter to click “Preview” button in order to preview drawing beforeit is released and thus avoid erroneous release.

Whenever a sheet is printed current lay and filter are considered to generate a plotting file.

10 DRAWING DETAILS

This chapter describes the process to follow to create drawing details and locate them in the library (of catalogue).

10.1 LIBRARY DETAI LS

Library details are grouped in families and families in a catalogue.

Process to insert details of library is the following:

• Select icon located in �Catolog Browser�. The following window will be displayed:

• Select family with a double click. It will show details compounding the family.

Catalogue

Families



• Select detail. A preview of the detail will be displayed.There are two methods for selecting details that is required to position. First, doubleclicking detail. Second clicking one time and selecting �Instantiate� option. In this step�Position� toolbar displays:

• Select a free space on the drawing sheet, in which ditto will be positioned.

It is possible to position ditto in a more controlled way by typing coordinates of application point inspaces of �Tools� toolbar or using icons on �Position� toolbar:

position ditto coinciding a detail point with a point of drawing sheet.

rotate ditto considering location point as rotation point

perform vertical symmetry to ditto

perform horizontal symmetry to ditto

From �Properties� window (it appears after displaying mouse right button menu or �Edit +Properties�), it is possible to redefine application point, angle and scale of ditto.

Select family

10.2 CREATION OF D ETAILS

There is a type of drawing sheets called �Detail Sheet� in which details will be created. Dittos will beinserted in �common� drawing sheets.

Tools used for creating details or inserting dittos are found in the following toolbar:

• Create a �Detail Sheet�, using the icon

• Create a new view on it using icon • In this view, create the desired 2D geometry• Activate drawing sheet and view in which ditto will be inserted.

• Select �Instantiate Detail� option using icon • From detail sheet, or from its tree, select desired detail.

It is also possible to select a ditto previously inserted.Position ditto in drawing sheet using the same method as for the library, that is indicatingwhere it is positioned, or using �Position� or � Tools� toolbar (see paragraph 10.1).
