    CATIA Part Design & Sketcher

    Basic Sketcher

    CATIA V5R6

    This section will cover the basic use of the Sketcher to create profiles for the Part Designpackage. This section will consist of four parts: basic shapes, profiles, constraints andmodifications to profiles.

    It is assumed that you have the default icons selected in the bottom toolbar. This includesthe snap-to-grid icon, the geometrical constraint icon and the dimensional constraint icon.These and the other options in the bottom toolbar will be discussed in more detail later inthe manual.

    The pictures in this manual are shown without a grid; this is to make them easier to see.When you are sketching, though, you will have a grid by default. If you want to turn thegrid off, you can use the pull-down menus.

    Basic Shapes

    This part will discuss the various shapes that can be created in the Sketcher using the icons

    on the Sketcherworkbench. The purpose of this group of exercises is to introduce how touse those icons and generate the basic shapes. The usefulness of these shapes depend on theprofile you are trying to create. Therefore you should just concentrate on what each iconallows you do and the corresponding shape it creates. Later in the class you will learn howto put everything together to generate your parts.

    The following exercises assume that you are in a new sketch. The first page shows you thenecessary steps to begin a new model and start a new sketch on a particular plane. Afterthat if you need help you will have to refer back to that page.

    Note: It may not be necessary to do all of the following exercises step by step. If you feel

    comfortable with the material then you can create all of the basic shapes on one sketch. Ifyou struggle or would like more information then you can consult the individual exercise forthat shape.

    CATIA Part Design & Sketcher

    Creating a new part with a new sketch

    CATIA V5R6

    Select the new icon in the bottom toolbar.This creates a new document. There aremany types of documents possible, so next you will choose which type you want.

    Select Part.

    Select OK. This will create a new part.

    Select the Sketcher icon.This will activate the Sketcher, but first CATIA needs toknow which plane you wish to use for your sketch.

    Select the yz plane. You can either select the yz plane symbol in the center of your screenor you can select the yz plane name in the specification tree. By selecting this plane you aretelling the computer that you want to sketch a profile in that plane. CATIA will rotate thewindow around so that you are looking straight down on (that is, normal to) the plane toperform your sketch.

    Note: Remember to refer back to this page if you have trouble creating a new part with anew sketch.

    Saving and closing the part

    Select the pull-down menu File. This will give you the option to use Save As.

    Select the Save As option from the pull-down menu. This will open up the Save Aswindow. You will need to specify your directory in the Save inbox and key in the file namein the File namebox.

    Select Save. This will save the document as a CATPart with the name you specified in thedirectory you specified.

    You will now want to close the window because you are finished with this exercise:

    Select the pull-down menu File. This will give you the option to Close.

    Select Close option from the pull-down menu. This closes the window and you are nowready to proceed to the next exercise.

    Rectangle

    CATIA V5R6

    This will cover the steps necessary to build a rectangle using the rectangle icon. This isuseful any time you need a box shape. All you have to do is specify two opposite corners ofthe rectangle and Sketcher will generate it for you.

    Select the rectangle icon.Notice this icon has a down arrow on it. If you select theicon at the location of the arrow the various sub-option icons will appear. For now you justwant the regular rectangle. Once you select the icon it should highlight.

    Select the origin point of the sketch plane. This will specify one of the corners of yourrectangle.

    Select somewhere up and out to the right. This defines the other corner of the rectangleand the rectangle should appear similar to the one below.

    Notice how the horizontal and vertical constraints automatically appeared on the rectangle.If you wish, you can save your document: call it rectangle with your initials.

    Oriented Rectangle

    CATIA V5R6

    This will cover the steps necessary to build an oriented rectangle using the orientedrectangle icon. This is useful any time you need a box type shape that is oriented at an angleinstead of being horizontal and vertical. You have to specify a location for the rectangle tobegin at and then specify the other end of the line representing a side of the rectangle. Afterdoing that then you have to specify a location for the height of the rectangle and then the

    rectangle will be generated for you.

    Press and hold the left mouse button while on the down arrow of the rectangle icon.This allows you to access the sub-option icons. You will want the oriented rectangle icon.

    Release the button on top of the oriented rectangle icon.The icon should changeto the oriented rectangle icon and highlight. Notice how the rectangle icon no longerappears; it has moved to the sub-options now. Remember you can always access the sub-options by holding down the left mouse button on the down arrow of the respective icon.

    Select the origin point of the sketch plane. This will specify one of the corners of yourrectangle. The next location that you select will define the orientation of the rectangle.

    Select somewhere up and to the right. This defines the other end of a side of the orientedrectangle. The next location that you define will determine the height of the orientedrectangle.

    Select somewhere up and to the left of the last location. This defines the height of theoriented rectangle and it should appear similar to the one shown below.

    Notice how the parallel constraints automatically appeared on the oriented rectangle. If youwish, you can save your document; call it oriented rectangle with your initials.

    Parallelogram

    CATIA V5R6

    This will cover the steps necessary to build a parallelogram using the parallelogram icon.This is useful any time you need a shape where the sides are parallel to one another but theycan be at any angle. This is similar to the oriented rectangle except the angle between sidesdoes not have to be 90 degrees. You have to specify a corner point for the parallelogram,then a point for the other end of a line representing a side of the parallelogram. Finally, you

    have to specify the endpoint for one other side of the parallelogram. CATIA will generate aparallelogram using the given points.

    Press and hold the left mouse button while on the down arrow of the rectangle icon.(Note: The rectangle icon may not currently be showing; if not, select the down arrow on theicon that is showing in the rectangle spot. If you just completed the last exercise then theicon will be the oriented rectangle icon.) This allows you to access the sub-option icons.You will want the parallelogram icon.

    Release the button on top of the parallelogram icon.The icon should change to the

    parallelogram icon and highlight. Notice how the previous icon no longer appears; it hasmoved to the sub-options now. Remember you can always access the sub-options by holddown the left mouse button on the down arrow of the respective icon.

    Select the origin point of the sketch plane. This will specify one of the corners of yourparallelogram. The next location that you select will define the endpoint of one of the sidesof the parallelogram.

    Select somewhere up and to the right. This defines the other end of a side of theparallelogram. The next location that you define will determine the endpoint of the otherside.

    Select somewhere up and to the right of the last location. This defines the endpoint ofthe other side of the parallelogram and it should appear similar to the one shown below.

    Notice how the parallel constraints automatically appeared on the parallelogram. If youwant, save your document and call it parallelogram with your initials.
