Or am I just going to have to get used to the fact that nothing does both well, and have to learn two different products ?
SketchUp was designed as an architectural modeler, it is not a CAD program at all. Certainly not as any sort of parametric mechanical design tool.

That it has been bent, twisted, stretched, banged on and otherwise mangled... and STILL works great for a number of purposes, is a tribute to the the original developers for making it capable of accepting third-party plugins and to the user base that has done so.

Had it been developed by Apple for example, everyone would be screwed. (I wouldn't have pissed on Steve Jobs if he were on fire while he was still alive by the way. )

Having run a laser for a while I can just recommend that you do cutting directly from a 2D drawing of the cut files.

Converting the 3D sketchup file for output to DXF isn't hard, it's just that if there is an issue it involves a lot of steps to fix it.

The other issue is it is difficult in Sketchup to see exactly what is send to the laser for cutting unless you view it as a 2D file from another program.

If you are working directly from the 2D cad program it is a couple of mouse clicks to fix and WYSIWYG.

Yes, you can draw in 2D, it is just difficult to get files sent to the laser correctly from sketchup.

So, you draw, export a file, hope it is translated correctly, and cut. If not correct, then you have to do the sequence again.

Easier to export to a 2D program that uses the format directly and send to the laser.
