PROJECTION - v14

projection                  Id=<nvar> {, Direction=<vector> }

Function

Project a curve against one or more surfaces.

The projection can have two different geometrical actions: Normal or Oriented.

A Normal projection is performed according to the normal of the surface at the point of minimum distance from the curve, while an Oriented projection requires the specification of a vector of projection by means of the Start and End parameters.

Parameters        

Examples:

# Select the curve that must be projected

     SELECT  XC

     ID1 = INF(28)

# Select the surface on which to project the curve

# NBB: This can be iterated

     SELECT  XF

     PROJECT  ID=ID1

     PROJECT  ID=ID1, Direction=(0,0,-1)

Notes

All surfaces under the Partition bar will be used as "target". This command generates a set of ordered curves that represent the curve projection onto the "target".  [Update X4[OCC])
