I am told from a CAD user that they can import the final model from another file into their current model, as a reference file, a lightweight version that will also update should the source be altered.
example…create an engine in one file and import it into the aircraft assembly file , change the engine size in the engine file and it updates in the aircraft assembly file.
Furthermore it might be useful not to bring in all the layers associated with the engine model, making even more busy the existing layers palette. Imagine the layers in there after wings , tailfin, undercarriage etc are all introduced.
I also wonder about effect on file size, having seen file size go from a few Mb to 70Mb just with a few semi spherical gulleys created from block instances of spheres.
Would the reference file overcome such ?
