Recurring solidworks_urdf_exporter (ycpss91255-research) errors, by impact

  1. 1SolidWorks to URDF to Isaac Sim gives colliders that fill every pocket and a pallet weighing 79 kg instead of 20. The simulator's default collider is a convex hull per mesh, so fork pockets, wheel arches and chassis interiors become solid, mass from solid CAD came out 4x too heavy, and multi-part link inertia was combined wrongly upstream.MCAD · Agent failure · 1 report74
  2. 2A fork's triage of upstream fixes for the SolidWorks to URDF exporter. One upstream change, the output coordinate system option, merged cleanly and passed tests but failed a live check on SolidWorks 2023: meshes stay in the global frame. Another ported fix had to wait for complete STL files before export.MCAD · Agent failure · 1 report66
  3. 3A SolidWorks to URDF exporter writes a robot file pointing at meshes that failed to save, and reports success. The STL and 3DXML save calls only log a warning on error, so the URDF gets mesh filenames anyway and the export dialog finishes normally.MCAD · Agent failure · 1 report66
  4. 4The SolidWorks to URDF part exporter writes wrong signs for the products of inertia. SolidWorks uses the opposite sign convention, the exporter converts once, rotates the tensor the wrong way round (R I R^T instead of R^T I R), then negates the products a second time. Computed from the exported STL, iyz is +2.01e-8, but the exporter writes -1.99e-8, and the committed example in the repo is wrong too, so robot sims downstream would run on bad dynamics without complaining.MCAD · Agent failure · 1 report66
  5. 5URDF export settings were one shared attribute, so two configurations of the same assembly could not hold different link trees. Renaming a configuration still orphans its settings.MCAD · Agent failure · 1 report66
