R6 lunchbox main components produce invalid breps

[Anton]

I moved R6 to a new machine including GH special folders.
Prior functioning scripts with Lunchbox main components now produce invalid breps.
This image looks strange with holes in breps although not in all views.
I tried removing and re-installing lunchbox with no success.
Any suggestions?

That looks more like a problem with the OpenGL clipping plane than a problem with the Lunchbox installation.
Please run the Rhino SystemInfo command and paste the result here.

One other user has reported a similar issue not too long ago:

Elements disappearing when zooming out

It was a bug a while ago, but got fixed in more recent versions. Since you’re running a recent version either someone put it back in again or it’s a different bug which manifests in the same way.

While not a perfect solution, it seems that if you explode the resulting Invalid Brep, then join it back together, it results in a valid/closed brep.

Looks like it may be an issue with the lunchbox plugin. Using the Brep.IsValidWithLog() method, it seems that something is not doing what it’s supposed to…

Got it, great thanks. Tested it works! Solved.
