ProjM3D

Command line: ProjM3D

Description: vertically project 2D entities on a 3D model

TopoLT toolbar:

Menu: TopoLT » 3D Model » Project to 3D model

With this command you can vertically project 2D entities to obtain a section line (trace) on a 3D model.

Accepted 3D models can be entities of type: 3DFace, PolygonMesh or PolyFaceMesh.

Accepted entities for projection are: any kind of 2D or 3D polylines (normal, spline-fit or curve-fit), circles, ellipses, POINT entity or TopoLT point.

Trace obtained on 3D model will always be and entity of type 3D Polyline.

POINT entities are moved to the Z coordinate. TopoLT points are moved only if the plane is set to 3D. At TopoLT points, the altitude value from the point block attributes is changed accordingly.

For this command there are also accepted closed 3D models such as by instance a sphere.
