About Creating a Cylindrical Surface
When you create a cylindrical surface using Restyle:
The midpoint of the base of the cylinder is its origin.
Restyle orients the cylindrical surface with respect to the reference direction. The orientation of the surface can be changed by modifying the angular dimensions.
You can select datum planes and axes as direction references for creating the cylindrical surface. If you select an axis as a direction reference, Restyle uses it as the cylinder's axis. If you select a plane, Restyle calculates the origin of the base circle automatically.
You can specify any two direction angular dimensions. Restyle calculates the third dimension using these two dimensions.
