About Trimming Surfaces
Trim surfaces to meet the edges of other objects.
An important step in the surface modeling workflow is trimming surfaces. You can
trim a surface where it meets an intersecting object or you can project geometry onto
a surface as a trimming edge.
When a surface is trimmed, the removed surface areas can be replaced with SURFUNTRIM.
and PROJECTGEOMETRY. It only restores areas trimmed with SURFTRIM.
The Properties palette indicates if the surface contains any trimmed edges.
Projecting Geometry onto Surfaces, Solids, and Regions
Similar to projecting a movie onto a screen, you can project geometry onto 3D solids,
surfaces, and regions from different directions to create trimming edges. The PROJECTGEOMETRY
command creates a duplicate curve on the object that you can move and edit. You can
also trim against 2D curves that do not actually touch the surface, but that appear
to intersect the object in the current view.
Use the SURFACEAUTOTRIM system variable to automatically trim a surface when you project
geometry onto it.
Options for Projecting Geometry
Project geometry from 3 different angles: the Z axis of the current UCS, the current
view, or a path between two points.
- Project to UCS – Projects the geometry along the positive or negative Z axis of the current UCS.
- Project to View – Projects the geometry based on the current view.
- Project to Two Points – Projects the geometry along a path between two points.
