UnrollSrf Error Message

I ran unrollsrf (not something I use frequently) and got this message:

Missing Dialog: the 18CUnrollErrorDialog dialog for this command is not yet implementedArea is 5.2928 sq inches (12.96 % ) smaller after unrolling

I’m not seeing that error here with Rhino 7.8 on Mac. Does it happen with a specific selection only? We may need the file and your SystemInfo results too. Thanks.

Here’s the file and my info.
Problem Unroll.3dm.zip (2.2 MB)

Another problem is the unroll results I get are quite bad. The surfaces I am trying to unroll (RED) are conical.

Thanks, I can see the issue now with that specific model. I filed https://mcneel.myjetbrains.com/youtrack/issue/RH-65104 for future reference. It looks like the error is a UI issue only on Mac, you can click the Warning option when using UnrollSrf and change the choice from Dialog to Command Line and you’ll get the info about the deviation in the command line history instead of the error. Regardless though, the dialog should come up on Mac too. Thanks for the report.

In terms of UnrollSrf getting a better result with these conical surfaces, I’m not sure it can. The Squish command actually gets closer to the Area but I’m not sure if that result is useful for you.

I’d like to create a photoetch mask.

I am surprised it cannot handle this cone as there is a 1:1, onto transform between this and a flat sheet.

In fact, methinks what I am getting is a bug. The output surface is a total mess. Dupborder shows how bad it it.

UnrollSrf has a problem with the trimmed holes. This problem is much more significant than the difference between Windows and Mac in where the error message shows up.

Problem Unroll DC01.3dm (8.2 MB)

The surface was duplicated and all holes removed. The surface with the holes removed unrolls properly.

The original surface with the holes unrolled matches the surface with the holes removed when unrolled along the outer edges. The edges of the holes obviously do not unroll properly.

The edges were duplicated to create curves on the surface. When the surface without holes is unrolled the curves do no unroll properly.

UnrollSrf is not working properly with this set of trim curves.

@BrianJ The YouTrack item needs to be updated with this information or a new YT item created.
