I have a sketch with a pierce relation to a curve earlier in the feature tree. This curve passes through the sketch plane at two points (imagine a circle drawn on the top plane, and a sketch on the right plane which is intersected twice by the circle). Is there any way I can enforce which of the two potential pierce points are used when the sketch is rebuilt? If I do a full rebuild [CTRL + Q] the relation picks the wrong point perhaps 50% of the time.

Can anyone give me any sketch tips to make this geometry more stable?

My actual sketch geometry is pictured here:

Doing adding some construction lines to connect a few elements together with a triangle like this might improve things, but this seems like a hand-wavy method to handle this situation.

Thanks!

Hi Ryan

I can't really see if this would work sorry, but its worth a shout. what came to mind was inserting a sketch point in your first sketch coincident with your curve and the second sketch plane (Right) or even a construction line in first sketch (or a second sketch on top plane) picking up both possible pierce points. Maybe a coincident relation to one of these points might be more stable.

Second thought Make a second sketch on top plane recreating your first sketch but making only 1 intersection point possible, recreate or convert entities and trim it back then pierce that. So using your circle analogy, keep your first sketch a circle, but pierce to a something just shy of a coradial semicircle
