I can't for the life of me figure out why "Trim one" or any other trim I've tried isn't working on this corner (see the attached file made in V23). Any ideas what's happening here?

Ok... I think I figured it out. I clicked measure and it looks like the Geometry (imported from Corel) is on different Z heights. Don't know why this is.

Any ideas how to fix this?

EDIT: actually I think I did most of the offending geometry in BobCAD. Not sure why it's showing a tilt in the Z plane. It should all be at Z=0 as I drew it.

So that's the next question... how in the world did the geometry get botched up. It looks like everything's got some weird Z tilt now. It should all be at Z=0 as I drew it.

Time to re-draw.This time use point coordinates and put 3 points,that would be one point for the end of each line and one point for the place of intersection.Now use line join.Or if you like where each line is in the x and y axis you could do a point end on the lines,then do a measure on each point and find where the z is at then translate to zero.After doing that to all 4 points,do a line join,then trim the intersection.

You do have another option. Sometimes you'll be working with geometry that is not flat on a plane, so you ned to flatten it.

This is easy to do, create a surface on the xy plane and project the geomerty onto that surface. This will flatten your geomerty so its all on z0.

I try to create a video for this tomorrow.

Trim Screen. For trimming things non-planar from a planar UCS.

But, if the drawing was supposed to be all at one planar level, then what Al said!
