I’m on a new M5 MacBook Air and Shapr3D was super performant in the beginning, but at least with the model I’m working on, it has slowed to virtually unusable levels when creating sketches (spinning and viewing the model is still very smooth). I describe my issue here: https://discourse.shapr3d.com/t/max-features-in-history/41160
I don’t know whether this issue is project-specific, if Shapr3D generally struggles with larger history models, or if this is a Mac-specific issue. I need to try testing on a Windows PC to see if things are any better.
