I started drawing a log house made up of logs of four different lengths, see attached image and model. I made each of the four different log types a component. The problem now is that SketchUp will not allow me to push door and window openings through these components. I tried making each log a unique component, but that didn’t help. I can push an opening through the center of a log, but the opening cannot intersect the edges, so I cannot get an opening that spans over multiple logs.
A detail you should know about: the native solid tools convert target components into groups following the operation. If you want to reuse them, you will need to make new components from them (Edit->Make Component, or equivalent on right-click context menu).
