Slice a Lofted Contour?


qball

Recommended Posts

I created a contour of an area using 3dpolylines and lofting them. Then I created a surface plane and I wanted to use the surface to SLICE the contour. But when it says "Select objects to slice" I pick the contour it says "No solids selected".

Is there another command? I thought it would be so simple, but apparently not.

Is it because the polylines weren't closed that it never actually created a solid?

Do I have another option?

When you list it, it calls it 'LOFTEDSURFACE'. To slice something I beleive that it would need to be a 3D solid, which would be why you can't slice it.

I tried to redraw them as a closed 3d polyline and when LOFT-ing it, it said "first and last must be coplanar".....?? oh well.

Use the THICKEN-command to make a 3DSOLID from the surface (be care to take a very small thickness as the 3DSOLID otherwise can get self-intersections). Furthermore I had problems to use the SLICE-command. So I made a BOX from the cutting plane and used the SUBTRACT-command to cut the 3DSOLID.

I have problems to upload the result (> 2MB).

In case of interest contact me personally via scj.schulz(at)t-online.de
