Possible to toggle onMesh on and off like Osnap?

Is it possible to have onMesh turned on until it is turned off. Like having an Osnap checked on and off?

This would be great for retopo of hard edge surfaces.

Hi @bisenberger,

have you tried _PersistentOnMesh named “POnMesh” in the OSnap toolbar ? It persists during a command at least.


Yep, I’ve been using it. It works very good, but would be nice if it didn’t
need to be activated for each command.

Hi Bill - can you post or send me an example of what it is you’re doing? I think I can picture the situation but it would be good to have a concrete example.
