How solidworks draws the inclined plane in the cylinder

1. Use the stretch command in soildworks to create a cylinder.

2. In the model tree on the left, click the datum plane on the same plane as the cylinder axis.

3. Look forward at the datum plane and draw a circle, and make a cut on the right side.

4. Look up at the datum plane, click on the stretching boss/matrix to pull out the inclined plane.

SolidWorks is an easy-to-use design tool based on feature, parameterization and solid modeling, which is developed on windows.
