Rhino 8 Sweep 2 won't show Isocurve Preview!

Hello,

When I use the Sweep 2 command in Rhino, the Isocurves don’t preview. Therefore I can’t add a Slash where I want to because I can’t see what Isocurves to fix.

There is a problem with your file.

I copied the lines and pasted them into a new file. It worked normally.

Your file works as expected for me.

Run the Rhino command SystemInfo and post the results.
