I am trying to determine the top level group (wall assembly) with my “Add Window” tool as I mouse over it. I know this is probably a very easy piece of code but as I look at the documentation for the InputPoint Class I can’t seem to find the correct method to use to accomplish this. Should I be trying to use the PickHelper Class instead?
This code should point you in the correct direction. Also, onMouseMove might be called many times a second so keep things streamlined.
# save time later by caching the reference to the pick helper for the active_view # when you create the tool def activate @ph = Sketchup.active_model.active_view.pick_helper . . . end def onMouseMove(flags, x, y, view) @ph.do_pick(x, y) my_object = @ph.best_picked # handle adding or removing my_object from the selection array Sketchup.active_model.selection.add(my_object) end
Just a FYI for general readership:
Thank-you, I think I have a better grasp of the PickHelper now, that is the route I will go with.
