What is happening this morning?
Unable to activate control points on solids or polysurfaces …
With the _PointsOn command, I can not see the volume edit points, but 1 to 3 points that only allow the displacement.
The problem is the same on the V5 and the V6.
To see these control points, I am forced to go through the Solid / Solids Modification Tools / Activate Points menu.
And every time I deselect the object, I have to go back through the menu to reapply these control points.
Very very painful
Is this a new bug?

For edit points on polysurfaces use SolidPtOn, not _PointsOn… Has been this way since V5. --Mitch
I’m dreaming … until yesterday, on the v6, it seemed to me that when we simply clicked on a polysurface, it automatically appeared points at the corners … By dint of working on surfaces in volumes maybe I do not realize what I’m doing anymore.
But remove me from a doubt … I’m not crazy anyway:
Until yesterday on the V6, when we clicked on a surface, the end points automatically appeared no?
No. For curves, yes (if you had that set in Options). Not for surfaces.
You’re right … I need to consult … I can not even realize what I’m doing. It’s hard for a designer … the beginning of the end 
But nevertheless, now when we use _PointsOn on a polysurface, we have 3 points that appear … pivot points it looks like. It is new?
These only appear on an Extrusion object, not a Polysurface. Yes, they are the axis and pivot points. If you have not modified the extrusion, you can stretch/shrink it along the axis with those points as well as rotate it.
Never seen before … Thanks Helvetosaur!
I think that it’s new or that it was not active in my interface before…
