Wirecut changing layer

Hey guys,
I’ve noticed that after upgrading to RH7 that the wirecut command with delete input = no that part of the resulting geo will remain on the original layer, but all other parts will change layer to the active layer. In RH6 all geometry would stay on the assigned layer regardless of the active layer.

Any ideas why this is happening? Is this a bug, or is there a reason behind it?

Many thanks,

On a simple test here, I’m not seeing that - can you post an example (before the wirecut operation)?

Sure. The blue is the active layer, the purple is a different layer. I’ve wirecut the base of the bezel and you can see part of the purple geometry change to the active layer.

Can you post a file with the just the bezel and the cutting curve? I still can’t reproduce that with something similar to your geometry.

Of course, here’s the file.Wirecut.3dm (1.5 MB)

OK, not happening here with your file either…

Can you run SystemInfo and copy/paste the results here?

I don’t have V-Ray installed here, don’t know if temprarily disabling that makes a difference?

I just tried it with Vray disabled, no difference.

I meant to say it’s with the KeepAll=Yes that this is happening, rather than the DeleteInput=No option.

I just tried it in a new default instance of RH7, same thing happening.

I assumed that, otherwise part of your object would have been deleted. However, there must be something else going on here - I have no idea what though. @wim - can you test this?

Does not happen here either - I would try with all of these plugins disabled in Options > PLug-ins page (then restart Rhino):

V-Ray for Rhino


Thanks Pascal - I just tried with all those disabled - same issue.

Hi Aaron - I see this in 7.5, apparently it has been fixed - you can get the fixed (7.6) version by changing the ‘Update frequency’ in Options > Updates and Statistics page to ‘Service release candidate’

Nice one! That’s sorted it out. Thanks guys, you’re the reason this community rocks.

That explains it - I am running the 7.6 RC here.
