Yes. I see your problem. The first thing I would do is ask your CNC workshop if they use any of the CAM software from the Vectric Suite (Cut 2D Pro/VCarve/Aspire).
If the answer is yes, then you can utilise Vectric’s very powerful vector import function which will directly import SketchUp files. In other words, you would simply provide the CNC workshop with a SketchUp file.
You have to structure your SketchUp models in an unorthodox manner and there is a bit of a learning curve associated. Dig into this thread and it should get you going.
If not, then, short of manually arranging your parts in a nice row, you are stuck using this script in order to create your DWG/DXF output file. You might like to try the following tip though:
- Go through your assembled model and locate any inverted components.
- Paint just the inverted ones a wild colour like bright orange.
- Execute your script to layout the components. (noting all the components scales have been reset).
- Simply go through and re-invert the bright orange ones.
Crude, I know, but this should only take a minute or two and is preferable to the manual layout method!
