Linear solid shadow of the model, how to?

A little help here if you guys don’t mind
I’m planning to draw a plan like this one in rhino and illustrator after:

But i’m not finding a way to display a linear solid shadow of the model possible to export in lines (curves) to illustrator

Has anyone done it and know how to do it?

Thank you already


Draw a groundplane to project the shadow on. Set the view to parallel projection and set your camera view in line with the projection of the sun rays. Select the geometry that will project the shadow. Run MeshOutline. Set CPlain to view. Select the meshoutlines and project them on the groundplane. These projected lines can then be exported to ai.

Perhaps someone knows an easier way.
