CATIA V5 Fundamentals
The Workbench Concept
Each workbench contains a set of tools that
is dedicated to perform a specific task. The
following workbenches are the commonly
used:
• Part Design: Design parts using a solid modeling approach
• Sketcher: Create 2D profiles with associated constraints, which is then used to create other 3D geometry.
• Assembly Design: Assemble parts together with constraints
• Drafting: Create drawings from parts or assemblies
• Generative Shape Design: Design parts using a surface modeling approach

Reference Planes
The default reference planes are the first three features in any part file. Their names are derived from the plane they are parallel to, relative to the part coordinate system:
XY plane
YZ plane
ZX plane
It is impossible to move or delete the planes.
The planes can provide a planer support on which to create a 2D sketch. Global coordinate system
General
11
CATIA V5 Fundamentals
Create a Sketch
1. Select a planer support (e.g.
datum plane, planer solid face)
from the specification tree or by
clicking the support directly.
2. Select the Sketcher Icon
from any workbench where is
possible to create a sketcher
(e.g. Part Design workbench).
3. CATIA switches the current
workbench to the sketcher
workbench; The viewpoint is
now parallel to the selected
plane.

Construction Geometry
Construction geometry is created within a sketch to aid in profile creation. Unlike standard geometry, it does not appear outside the sketcher workbench.
Construction geometry is shown in dashed format. When the “Construction/Standard element”icon is on, all sketched elements will be created as construction elements.
You can also toggle any elements from standard to construction, or vice versa by clicking the “construction/standard element”icon.

This is a line on the sketch
When the cursor is on the line, the line will turn in orange and an empty circle appears next to the cursor
When the cursor is at the endpoint of the line, a solid circle appears next to the cursor
CASE-1
CASE-2
We are going to draw a line, which is tangent to the arc
Before clicking the second point of the line, move the cursor until the system can detect that the line is tangent to the arc. Click and confirm the position.

Constraining the sketch
• Dimensional Constraints
(click the icon, then select the element(s))
• Length
• Distance
• Angle
• Radius/Diameter
Remark: To create the dimensions continuously, double-click the icon so that the icon is always on until you re-click it again
• Geometrical Constraints
(multi-select the two elements by pressing “CTRL” key and click the icon)
• Perpendicularity
• Horizontal/Vertical
• Concidence
• Tangency
• Symmetry (multi-select the elements on the both side and then select the axis)
You can also create constraints with other sketches and 3D elements out of the sketch

Controlling the direction of a
dimension constraint
The default dimension direction is
parallel to the line between the
circle centre. To change the
direction to horizontal or vertical,
right mouse click and select the
desired orientation.

Color and Diagnostic
1. White: Under-constrained
2. Green: Fixed/Fully constrained
3. Purple: Over-constrained
4. Red: Inconsistent
Only case 1 & 2 are allowable
in CATIA; for case 3 & 4, you
must fix the error before
quitting the sketcher workbench, otherwise a
warning message will pop-out

View Orientation
• By default, the screen is parallel to
the sketch support.
• To making constraints between
the sketch geometry and the 3D
element, you may need to rotate
the model into a 3D view.
• To return the default orientation,
select the “Normal View” icon.
We can create a distance
constraint between the circle
centre and the solid edge
