Projection

This command projects one object onto another:

		Object to project
		Cloud	Point(s)	Polyline/ Set of Polylines/Line
Project onto	Plane	¹	¹	¹
	Mesh	³		²³
	CAD surface	³		²³
	Line		¹
	Polylines
	Surfacic features

¹:In these cases, you will have the choice between finite or infinite projection.

²:In these cases, you will have the choice to Add points to better follow the shape.

³:In these cases and if you select Along a direction, you will have the choice to compute the projection in both directions.

Select the object(s) to project and launch the command.

Select the object to project onto (destination object).
Choose the projection type:
1. Shortest distance in 3D
2. Along a direction: define the direction vector
Set contextual options (refer to the table above):
1. Use the option Finite Projection if you want to project on the line or plane strictly.
2. Use the option Add points to better follow the shape if you want to fit your projected polyline on the shape of the mesh (points are added so that the polyline better follow the mesh shape).
3. You can project on Both sides of your defined vector. It's really useful if your cloud or polyline oscillates around the mesh. In this case, the result will be the nearest projection in the defined direction.
Validate the command by pressing OK, or close the dialog box with Cancel.

Tip & Trick: keep unprojected segment()

if the object to project is a polyline or a set of polyline, you can keep the part of the input that are not projected on the mesh. The unprojected segments are displayed in red. However, if the object to project onto the polyline is an infinite plane, Unprojected segment(s) won't be necessary.
