The featuretree IR: an Open Feature-Tree Format, Emitted Natively into Several CAD Systems and Checked by Re-Reading

When a program or a language-model agent writes a part, a person still has to be able to open it, see how it was built, and change one dimension without starting again. That needs a shared, small description of the feature tree (the "timeline" every history-based CAD system shows...

Cooling a Quasi-Direct-Drive Joint Motor from Inside the Copper: A Simulation-Only Design Study

Quasi-direct-drive (QDD) robot joints trade gear ratio for transparency, and their continuous torque is set by how much winding heat the housing can shed. This preprint tests one hypothesis: that drive electronics are now efficient enough at high current that heat is the remainin...

featuretree: Verified Recovery of Editable CAD Feature Trees from STEP, for Open CAD Systems

Importing a STEP file into a parametric CAD system yields a single frozen solid: the design history is gone, and no pad depth or hole diameter can be edited. Recovering that history is a well-studied problem — the acceptance criterion used here was stated as a definition by Gupta...
