I keep encountering this problem in Sketch Up Make.
My 3D design program have pre-defined library items such as cabinet doors and furniture etc.
I need to export them to Sketch up Make (free version, not Sketch Up Pro) in order to modify them.
So I exported them as Collada file format.
Once I’m in Sketch up make, I imported these items as Collada file (I selected ‘Merge Coplanar faces’) and draw circle or rectangle shapes onto them.
Then I tried using push/pull tool on these circles or rectangles to create holes into the imported objects.
But I kept getting a protrusion of the circles or rectangles into these imported objects.
Please see screen shots.

Can anyone please help me?
I even tried “select all” and then click "Intersect faces’ and ‘with model’ or ‘with selection’ and then erase the circle or rectangle but it still does not work.
