The trim operation in Trim/Split trims a mesh using cutting elements.
Before you begin:
Ensure that the mesh is exempt of non-manifold problems.
Select a terrain to
trim.
Select the Cutting elements.
Cutting elements can be:
Discrete polylines
Curves
Planes
Surfaces
Meshes.
Note:
The curves resulting of the projection of the cutting elements on the mesh must
intersect
each other or intersect free edges of the mesh. The portion of curves not taken into account at intersections must be as short as possible.
Select a Projection type (applied to all cutting elements).
Optional: Select the Preview check box (time-consuming).
Select the Trim option.
Click the scissors icon in the dialog box and pick the area you want to
remove in the work area.
