Slice Solid Mutiple Times?

[qball]

I've made some solids by extruding closed polylines as shown in the attached file. It's a path with retaining walls down the side of a hill. I sliced with Planar Object (2d polyline) the solids to create a path with a slope. But I want to show roughly where the underside of the wall will be, so I tried to slice the solid again and it says "Slicing plane does not intersect the selected solid." or it says "pick a side to keep..." and it just doesn't slice the solid at all. Any thoughts? I did note that before I sliced the original extruded polyline that there were multiple grips on it, and when it's a sliced solid there's only one grip.

well if your error is slicing plane doesnt intersect object, its just that. How are you selecting your plane?

[JD Mather]

Attach the file here. Indicate the slicing plane. (you might create a planesurf to indicate this)

The slicing plane was a 2d polyline that I 3drotate 'd about the Yaxis to the desired slope. The help menu said the slice - planar object had to be a 2d polyline, not 3d.
All the solids have a flat bottom elevation of -40 feet, but I want to slice the bottoms off so the bottom slopes up the hill as well.
I was just moving my 2d polyline up and down the z-axis to the desired elevations.

sidenote Shift: nice wheelie. what are you riding?

Something like this?

(Right click on the zip file and select Extract All.)

Yes, quite a bit like that.
Planesurface instead of 2d polyline - CONVTOSOLID command. Thanks.

[JD Mather]

CONVTOSOLID command. Thanks.

No no no. Slice with Surface option. See the tutorials in my signature.

after listing your yellow surface I saw it was a Planesurface. So on mine I did CONVTOSOLID to my rotated 2d polyline, then SLice - surface option and it worked. Tried CONVTOSOLID again on a different polyline. Didn't work.
Tried CONVTOSURFACE and that seems to work on polylines.

I elected to keep both sides. After I did the Slice I moved the parts to show that they were separate.

how the top of a solid which is shelled is removed? Guide plz.
