Use draft checking to determine if a part within the model is drafted properly to allow the molding or cast result to be removed cleanly.

Draft checking is based on a user-specified draft angle and pull direction (the direction in which the mold or die opens). To determine if the surfaces of a selected part should be modified with draft, the system checks the angle between the planes that are normal to the surfaces of the part and the pull direction.

By default, sufficiently drafted surfaces appear in blue, the opposite side of the pull direction, appear in red, surfaces without draft appear in light gray. Surfaces that require additional draft appear in a color between light gray and red or blue to indicate that they deviate from the required draft angle. You can use the options in the Color Scale dialog box to set the Model Display and color options.
