Cut the surface with a straight line?

Please help how to cut 1 of the 4 corners?

If this is a single (joined) polysurface, you can’t. There is no way to split an object that is ‘closed’ in one direction at only one spot. You would need to split the part at at least two locations in order to be able to form two separate parts.

I think sketchup can do it.

Is there a way to close the 2 lines to be perpendicular? please help

Hello - if you want open edges on an otherwise closed loop of faces, use UnjoinEdge.

-Pascal

i tried that command, but it can’t do what i want?

As far as I can tell from the image, there’s no edge to unjoin on his horizontal faces. He would have to use SplitFace or something like that to create the splits.

Sketchup can do things that Rhino can’t. Rhino can do things that Sketchup can’t. The two have completely different systems of working (NURBS/Mesh).

Right, I really have no idea what the user is trying to do.
@noithatchiaki - please post a file with the object and some details about what you need to accomplish.

I’m trying to spread them out quickly without having to rerun the (loft) command for UnjoinEdge

[image]

yes! i got it, but i thought there would be some script to do that?

hello - SplitFace on all four horizontal faces at the corners, then UnjoinEdge the corner edges like so:

Then UnrollSrf, Explode=No
