Help me model this wall/bench!

for mcneel forum.3dm (3.9 MB)

You can see the reference wall/bench on the left that I modeled previously, but now I need a new version where they wrap around a circle with outer walls sloping so they meet at the tops; wall heights increase gradually, but I still need the front of the wall to smoothly transition into the front lip of the bench.

Please help. I cannot figure this out!

Opening your attached file instantly crashes Rhino 8 macOS.

That seems fine here. What happens when you import the file instead of opening it?
Seeing that your last crash report in our system is from October 2025, I take it there is no crash reporter when Rhino crashes?

Instant crash upon import. Very odd, because that never happened since starting to use version 8.

And that was with all viewports set to Wireframe, or doesn’t that make a difference?
Please post the SystemInfo data from your Rhino.

Yeah it is possible to model this bench/wall

Thanks, Wim, makes no difference. Instant crash. Here’s the Sysinfo file.

Update Rhino? We are in sr34 I think

Hi Angie -

Sorry that your question got derailed.

It’s not clear to me what you are trying to do. If you provide more information, perhaps someone will be able to help you out.
