Split Lines

The Split Line tool projects an entity (sketch, solid, surface, face, plane, or surface spline) to surfaces, or curved or planar faces. It divides a selected face into multiple separate faces. You can split curves on multiple bodies with one command.

You can create the following split lines:

Projection	Projects a sketch on a surface. You can pattern split line features that were created using projected curves.
	You can create split lines using sketched text. This is useful for creating items such as decals.
Silhouette	Creates a split line on a cylindrical part.
Intersection	Splits faces with an intersecting solid, surface, face, plane, or surface spline.
