I am using a PCB layout program for circuit board design and export the 3D information for import into a mechanical CAD application as my standard design flow. I am considering a permanent move to Sketchup and have been trying to make the two CAD apps work together, to no avail.
There are 3 main issues that don’t make it easy to go to Sketchup.
1 - The PCB CAD software I am using is not very flexible with what is produced in the DXF output; so I have to use what it gives me (as everybody does). Its numeric base is in nanometers or something ridiculously small.
2 - No matter what Import Units I select with Sketchup it comes in HUGE. For instance, 1.750" = 145833’ 4". I have had it up to 884,000,000’.
3 - With the smallest import size (1.750" = 145833’ 4"), when I Scale the object down, I can only go to 1’ 5", and no smaller. This seems like a numeric limitation for the Scale feature in Sketchup.
If Sketchup could import micrometers or nanometers I could probably Scale it down to the correct size. At current, I do not have a good design flow path to get my 3D PCB’s into Sketchup to design around or validate a higher level assembly. I would prefer not to write/run a script to convert the DXF units, or run it through another CAD program to have a better starting scale units.
Any help to resolve would be appreciated. Thanks -Jeff
