Component origin as inference point

[Mark ADDS]

Is this possible / does it exist?
When I drag a component into a drawing the component's origin is the point of insertion. Once it is inserted, however, the component's origin point seems to no longer be available as an inference point. Am I correct about this?
Thanks,
Mark

Yes, you would need to place a construction point at the origin point to have a point for the move tool to infer.

Or if you've added that component then just use your component library to bring in a new instance and delete the existing one if it is placed incorrectly.

Thanks Rich.
I see no native capacity for a permanent construction (guide) point. Is that correct? When I create one w the tape measure tool, or by drawing a circle and then deleting it (as suggested elsewhere), there is nothing (no "point") selectable or that shows up as an entity.
Thanks,
Mark

I use a plugin, Pen Tools+, to draw points.

Not sure if SketchUp does it natively?

There are several tools to draw cpoints [aka guide-points] - including Rich's excellent PenTools.
http://sketchucation.com/pluginstore?pln=Pen_Tools
and
http://sketchucation.com/pluginstore?pln=tt_guide_tools

This simple snippet pasted into the Ruby Console adds a cpoint at all selected component-instances' insertion points.
Naturally, you'll need to have Guides set to be visible to see these cpoints...

Sketchup.active_model.selection.grep( Sketchup;;ComponentInstance ).each{|e| e.parent.entities.add_cpoint( e.transformation.origin ) }
