STEP 1: Add a sketch-loop to a Part

STEP 2: Add a Profile

2.Click one sketch-element that is in the sketch-loop

3.Click in the Command-Manager

The Profile contours are (default) PINK

In the Front-View the Profile contours hide the sketch-loop.

Note: You can edit the color of the Profile contours in Application Settings | Graphics tab : Display Colors.

The Profile and Extrusion in the Assembly-Tree

If you expand the Mechanism in the Assembly-Tree, you see the:

•Part

•The Profile is a child to the Part

•The Extrusion is a child to the Profile

The Profile and Extrusion in the Graphic-area

The Profile has two contours - the Primary-Contour and Secondary-Contour.

The default position of the Primary Contour is coplanar with the sketch-loop, and Mechanism-Plane.

STEP 2: Open the Extrusion dialog

1.SHIFT+CLICK the Pink Profile

The Profile and the Extrusion show in the Selection-Window.

2.Right-Click the Extrusion

In the Contextual menu

3.Click Edit element

The Extrusion dialog is open.

STEP 2: Edit the Extrusion

1.Enter Extrusion Depth = 30

2.Enter Extrusion Offset = 10

Distance to Primary Contour = ( Part Offset + Extrusion Offset ).

To show the Extrusion in the Mechanism-Editor use :

•Visibility toolbar > Show Solids in Mechanisms.

However, hide the Extrusion again

•Visibility toolbar > Hide Solids in Mechanisms.

STEP 1: Edit the Part

STEP 2: Click Geometry toolbar > Add Circle

Add two Circles. Use these two techniques.

TECHNIQUE 1

1.Hover above a Point, so that it becomes red

2.Click and Drag the radius of the Circle.

The center-Point merges with Point when you release your mouse.

TECHNIQUE 2

1.Drag the Circle near to the Point

2.Click Constraints toolbar > Add Coincident (see left)

a.Click the Circle near to the end-Point of the CAD-Line

b.Click the end-Point of the CAD-Line

STEP 3: Add Dimensions and Constraints

1.Click Constraints toolbar > Add Equal Constraint

a.Click the two Circles

2.Click Geometry toolbar > Add Dimension

a.Click a circle

The Dimension dialog opens:

3.Right-click the dimension-box

a.Click Round and the Dimension becomes the nearest integer that is exactly divisible by the spin-increment value.

b.Edit the Spin-Increment to be 1

c.Use the spin-box tool to edit the value to 16

(Please ignore the actual numbers in the data-boxes to the left).

You have fully-defined the Circles:

•the centers are coincident with Points in the Part

•the Radii are equal; one is dimensioned

The sketch is Green in the Part-Editor to show it is fully defined.

4.Close the Part-Editor – Double-click a sketch-element.

We will now add the Holes through the Extrusion.

STEP 1: Click Solids Toolbar > Add Hole (above the graphic-area)

You must click two elements to do Add Hole.

1.Click the prepared Circle in the Part

2.Click the Profile through which you want to cut the hole

3.Click in the Command-Manager

Do 1-3 again to add the other Hole.

•They cut through the Extrusion.

•They are a brother (or sister) to an Extrusion and child to the Auto-Profile or Profile
