UVs are scaled drastically when importing from Solidworks. When comparing it to an Engine Cube and adding a texture to it you can see the difference in UV scaling. The texture will need to scaled to 0.02 (UTiling, VTiling) to match that of an Engine Cube.
This has been reported and tested in 4.20 (4.20E3). This has been reproduced in 4.19.2 (0.182).
Results: UVs are scaled drastically up
Expected: UVs are scaled normally
