so UV lines I thought you could use to trim a surface however this never works for me it will not even let me pick a 3d sketch to use as a trim.
this is so frustrating that almost everything we try in our designs that half the tools do not work the way you wish.
Hi Travis,
It appears to have let you select the 3D sketch, but in the image it doesn't appear to enclose a 'separate' area to then be removed. If you could upload the part we could take a closer look?
