Projection of a smoothing on a non-concurrent plane

A smoothing 130mm apart from two entities // a circular diameter 60 to a square 30x30 with rounded corners 2mm the starting origin is in the center of the square entity, the center of the circle is offset in Y by 10mm / from the square entity.
We place a plane 11 mm outside the volume created // to the cylindrical entity and we would like the projection of this volume on this plane to have a DXF of wire conduct
And well I don't know how to do it and I'm sure there is a way to do it simply.
The projection is not circular and rather ovoid.

Hello, I didn't find the solution by going through the volume tools but by going through the surface tools which have this possibility to project a smoothing on a plane. I'll get away with this trick. Thanks to those who looked into the subject

Hello and welcome Laurent_DEBOVE,
We would need at least a screenshot, version of Solidworks, so that we can better understand and help you...
