System Information
Operating system: Windows 10
Graphics card: GTX 1050

Blender Version
Broken:

  • 3.1
  • 3.2.0 Alpha, branch: master, commit date: 2022-04-19 14:30, hash: blender/blender@721a9bc35c

Addon Information
Name: Edit Mesh Tools (0, 3, 6)
Author: Meta-Androcto

Short description of error
The bpy.ops.mesh.offset_edges() operator does not respect the scene's unit settings. Its width property is unitless.

Exact steps for others to reproduce the error

  • Set units to imperial (Scene Properties > Units > Unit System)
  • Add a plane and switch to edit mode
  • Select all vertices and apply Offset Edges (Sidebar > Edit > Mesh Tools > Edge Tools)
  • Set width for offset to 1.0
  • Measure offset distance with measure tool. It is always 1m (3.28084 ft).

What particular part of the add-on does not handle the changed scene units properly? Please provided step by step instructions to reproduce the issue.

Hi Robert,

Here are steps to replicate the problem:

  • Start blender with general file
  • Set units to imperial
  • Add any mesh shape (ie simple plane)
  • Edit plane in edit mode and launch Mesh tools > Edge Tools
  • Offset edge by 1.0
  • Measure offset difference in plan with measure tool. Result is always 3.30 (1m = 3.30 feet)

It would seem mesh tools sticks to meters regardless of what the current project units are set to.

That is the case because the width property is not marked as a length. Adding unit="LENGTH" to the property should fix this, if I'm not mistaken.
