create cloud projection of points on the face of a solid

[GIULIA ROSSI]

Hello guys after I imported a cloud of autocad points, how can I create a projection of the contours on a plane ( parallelepiped ) that will serve me for 3d printing?

I don't think autocad can do that. . .
you can project objects on a surface but not on a face of a solid

you can also on a solid, the problem is that the projected object crosses it, it could project on a surface corresponding to a face of the parallelepiped and then move objects.
giulia, see well the differences between projectgeom and imprimi
