Yes,O.K, I phrased incorrectly. I want to use a warehouse model(that someone else made). Export a specific angle in 2D. Do a full blown photoshop painting over it. Present it to the director.Is this legal?
That sounds like it's OK. Your limitation is not to pass on such warehouse models 'for money' [either as they are, or combined into your own models - at least without very very extensive changes to their form]***. However, using them as the basis of your own 2d imagery seems uncontentious. Selling an image isn't selling the object [unless of course it's substantially an image already - like a 'texture'!]. BUT you ought to read the terms of the warehouse to satisfy yourself.
Even if you are quite sure that there is no issue, then it might be polite to inform [ask?] that SKP's author of your intentions... Put yourself in their position - if you were to put your own model into the warehouse, with unfettered download etc, then would you expect others to be limited in using it, other than you'd be miffed if they sold your work as it it were their own...
***Models obtained from elsewhere will often have different limitations - e.g. FormFonts and similar providers say you shouldn't pass on their models to others at all, evenly freely, also you can often only reuse them while you are still paying the annual 'license'; but again using your own 2d images of these models is not seen as contentious.
