In Rhino 6 WIP I’ve noticed a weird issue when using the Trim command on multiple intersecting curves. To illustrate I made this quick example using the “Circle tangent to 3 curves” command: [Top_01] Trim functions perfectly while in the Top View: [Top_02-Trim] However the problem arises when …

That works fine here so there is something more file- or system-specific going on. Would you mind sharing a 3dm file?

Here’s my 3dm. Trim_Bug_01.3dm (53.2 KB)

I can reproduce this when I turn ApparentIntersections on. I always keep mine at No, so this doesn’t bother me… :innocent:

This still happens to me even when turning off ApparentIntersections, which I’m glad to learn can be turned off by the way. :slight_smile:

Hi Derek, Wim - thanks for the report. https://mcneel.myjetbrains.com/youtrack/issue/RH-43352 -Pascal

Hi Pascal, I’m not sure if that means that you got it reproduced that it also does that with apparents turned OFF… -w

Hi Wim - here it is as you-all described - with ApparentIntersections=Yes the trimming is weird, with No, it’s OK. -Pascal

[image] Derek_Heming: This still happens to me even when turning off ApparentIntersections Am I reading this wrong? :hear_no_evil:

ork. I see - well, here, with Apparent=No, the trims work as expected… @Derek_Heming - can you verify that it does not work right for you is ApparentIntersections=No ? -Pascal
