IPT - 2D Sketch - Scale

[MattH_Work]

Has the scale command within an IPT 2D sketch been exposed to the API, if so are there any examples?

If not, I appreciate I can start the command through code via

oCommandMgr.ControlDefinitions.Item("SketchScaleCmd")
Call oControlDef.Execute


But how would I go about selecting all the geometry in my sketch in a way that the Scale command would see it as pre selected when the command starts?
(I can add the geometry to a selection set and/or a highlight set, but the scale command opens with the 'Red' select arrow, it does not see my geometry)

Typical, discovered comma in the wrong place just after posting, but...

I can now preselect my geometry, fire the scale command and have the selection accepted, but I have to give a base point, any idea on automating this (in my case, the base point can be anything, any geometry, origin point etc)

Cheers
