I thought for sure that I have, in the past, snapped an object element to self. In this case snapping solid wall extrude to another edge/point in same solid.

Has this never worked? After 8 years of using MOI did I just never try to snap an object element to itself?

Hi Charlie, it works in other situations like when moving a whole object using Transform > Move.

I've got a tune-up for the next build which will be soon to make it work with moving faces or extrude.

For now use Draw curve > More > Point to place a point object where you want to snap before running the command.
