About Construct Steps
Construct steps enable you to create Constructed entities by referencing existing Measured entities. Unlike Measure entities, which are displayed in magenta, Constructed entities are displayed in cyan.
CMM allows you to create the following types of Construct steps:
Plane—Construct a planar entity.
Line/Axis—Construct a linear entity.
Circle—Construct a circular entity.
Cylinder—Construct a cylindrical entity.
Sphere—Construct a spherical entity.
Point—Construct a single point.
