Hi Kris,
Bricksmith automatically converts '\' to the Mac path separator. You
never need to manually edit Official or Unofficial part files to make them work in Bricksmith.
There is a help page in Bricksmith which explains how to correctly install Unofficial parts. It's a simple procedure. Please follow the directions under
Help > Getting More Parts, and look under
"The Easy Way". Here's the relevant exerpt:
- Download the complete archive of parts in the tracker.
- Rename the downloaded folder "ldrawunf" to "Unofficial"
- Move the folder to LDraw/Unofficial
If you encounter any errors after using this method, it means you didn't put the Unofficial folder in the right place.
Thanks,
Allen
