Drawing - Sketch trim

Hey Scott,

I need the JCM file attached here for that one. That's the best way to reproduce that.

Sorry for the delay getting back to this, Scott. I’m usually much quicker with issues, but I got deep into the agentic and 3D scanning work that finally went out yesterday.

I checked your video and file. That little line above the corner is an extension line from the 110 mm dimension. The actual sketch edge ends at 38 mm, but the dimension still references deleted geometry at the old 40 mm height. That’s why Trim won’t touch it.

Your file has three dimensions and four constraints with missing references. JC3 should have flagged those. Current versions clean up dependent dimensions and constraints during trimming, but that doesn’t repair ones already saved in an older file.

I’ve planned a fix to clearly mark broken references, stop drawing misleading dimension lines, and let you reattach dimensions to existing geometry—including diameter dimensions on arcs. Repair will measure the existing geometry by default; restoring a driving value will show a preview first. Broken constraints can be removed and recreated, and printing will warn before proceeding without unresolved dimensions.

For now, deleting and recreating the 110 mm width dimension against the existing geometry should clear the protrusion. The other dimensions and constraints also need reviewing. Thanks for attaching the file—it made the cause clear.
