Can you make hole from object?

Hi, is there any extension, that will switch your object into "hole, and if you group it with something, it will make hole to the other object? There is function on this in autocad, but i need it in sketchup too.

Thank you for your time.

You can use the Solid tools with a solid object for the hole. Show us an example model where you want to do this.

I want to do front, top and side of the car. But i dont know how to make it together. I have top already.

SketchUp has no concept of “negative space”, so a hole can’t be an object per se. But you can use solid tools to subtract one solid object from another, leaving a hole in the latter.
