Rotate Region causing crash

[micheus]

Just by selecting a face and applying Rotate->Region I'm getting a crash:

Code:

I tried to recreate the issue with a simple cube. Couple tries and I failed to get the crash. I was maybe going to look at the code for fun.

Can you share the model or simple setup ?

[micheus]

I used a box; selected all the Faces; used Inset [LMB] a couple of times on them; the latest selected face (the most inner) was the one a was trying to rotate.

I already now what is causing the crash. It's strange that the angle parameter is a list. Getting its value fix, but I need to check it better since in cases like yours it works.

Thanks for the test and feedback.

I couldnt reproduce the crash here, Micheus...

[micheus]

Very strange that.

I'm using 2.1.5 and get it all the time - even for the single face in a cube like ggaliens reported do not have the problem.
I did the same test with the older 1.5.3 I have installed here at work and it works as expected.

Please do a test for me. make a backup of your wpc_rebion.beam and replace it by this one.
It's under ...\plugins\commands folder.

In this situation, I'm expecting you to get a crash since it fixes my crash.

[tkbd]

I replaced the file and ,test.
Then I get a following error message.
(When I did the Region command,get error instantly, I could not dragging selection(s). )

Code:

Thanks tkbd.
I need to figure it out, otherwise I cannot try to add the Magnet option to this command - something I was trying to do when stumble on this crash.

[tkbd]

I compared about behavior other rotation commands in the magnet mode.
(I use the no modified region_rotate plugin file in v2.1.5.)
Rotate Normal and Regon behaver there is a similar part.

For example Even when these two commands in magnet mode,not instructed for 2ndary selection for magnet boundary set.
Is it a specification or a bug?

And I found another interesting message in other rotation command.

Make a cube,and all faces select ,and inset x2

Then did Face mode:Rotate > Free (with Magnet mode (use click + Alt key ))

Message dialog: Magnet Rotate on multiple face regions reguires an explicit rotate origin.

This message may indicate a special condition in the magnet mode.
I wish it will be a hint to the solution of the problem.

Cheers.

Guys, my bad.
I'm working in the Dev version and I didn't noticed the recent changes to wings_drag.erl - t's a work in progress. So, I found a future bug.

[tkbd]

I see .
I look forward to new features.
