Chapter 3: Working with Sketches
FIGURE 3.48
Creating a plane from tangent and coincident constraintsNote
If the view is already normal to the selected plane, and you double-click Normal To, the view switches to 180
degrees opposite. For this exercise, it doesn’t matter which way you view the part, but from the top is better
than from the bottom because the view is clearer. n- Select the sketch plane either from the graphics window or the FeatureManager.
Press the Spacebar on the keyboard and double-click Normal To. There are other
ways to access this command, but this is the method that will work regardless of your
interface setup. You can use whatever method you prefer. - Use the Centerpoint Rectangle to create a rectangle centered around the temporary
axis of the large cylindrical face. Make sure that the centerpoint, which is the first click
you make, picks up a coincident automatic relation with the temporary axis. Make sure the
second click to place the corner of the rectangle does not pick up any automatic relations.
You can tell if any relations have been applied if you go to the View menu and activate
Sketch Relations. Make sure the centerpoint has a coincident relation and that none of
the corners has any relations.
Note
The temporary axis is not on the same plane as the sketch plane, so if the view is not normal to the sketch
plane, picking up an automatic relation between the centerpoint of the rectangle and the temporary axis will
be difficult. n
