Can we import Solidworks file in Photoshop?
it does have a 3D option but does not have sldprt, sldasm or prt extension when inserting a file.
PS can open .obj and .3ds. if you can export your SW model to these format then you will be able to import them in PS CS4 or later.
there is another way to do this but you have to download an add-in from Labs Collada to export your files to DAE format which can be opened with PS.
