Lately i've found myself quickly mocking up companies logos for conceptual work to put on a building design, throw on a tennancy etc for renders or revit live use.
Generally it produces a much better product to create a face-based family or similar and do a few quick extrusions over a .jpg than to insert the logo as a decal.
If there was a colour picker tool, and potentially an option to create a generic material based on the selection it would be much more efficient than also dropping the logo into paint/photoshop for the RGB values.
