Hi,

I was checking the mesh2 and comparing it to the current V6 mesher when I ran into this issue around the trimmed holes:

Hi Willem - thanks, I see this.  
@Willem - changing ‘Chord height’ in the advanced parameters seems to sort it out, here. (.01 \> .001)

Seems to be the same as ‘Tolerance’ in the simple controls. Setting an aspect ratio at a higher tolerance also cleans it up here.  
The V6 mesher seems to like it better though, I concur… I’ll add this example to the heap - thanks.
