Dear McNeel,
Just installed the new release of Rhino, very nice.
At the moment, transparency of the colors created by the command _draftangleanalysis on a patch surface are not working. This is an issue that i had & reported one time before in Rhino6, see this tread: DraftAngleAnalysis and transparency in Rhino6 not working - #12 by jeff & https://mcneel.myjetbrains.com/youtrack/issue/RH-44285
It seems that this issue is back again, hopefully it can be fixed.
Other analysis commands like _curvatureanalysis works as it should be.
I hope that the fix will not take as much time like the last time, thanks.
