Slow snap in large mesh

I use rhino often for reverse eng from scan data.
In rhino 6, I notice very slow displey performace when I use snap in scan data.

Is only my issue?

Thank you


Thanks for the report Marco. I will use some large meshes here to compare v5 and v6 but can you share a specific file that shows the slow down? to my attention… you can leave the default email as

Also, are you using a default display mode like shaded or ghosted. I want to make sure I use the same display settings as that might be a factor.

This could be caused by the mesh edge snapping changes in V6. In current build mesh edges are being processed (=slow) even if the mesh edges are not Near, Mid, Int or Perp snapped to.

This should work better in a near future WIP.
