This add-on provides technical measurement tools for evaluating the circumference of 3D models. It is structured specifically for technicians and Certified Prosthetists Orthotists (CPOs) working with scanned data or preparing devices for physical production.

The workflow requires placing the model's distal end at the world origin with the Z-axis pointing up. It generates measurement circles starting from the distal end using customizable intervals, and includes operators to clear individual or all measurement circles. The tool requires the Blender scene unit scale to be set to 0.001 with the length unit set to millimeters.
