All so often people are deleting logos (small jpegs) found in the same folder as exported drawings from Revit to dwg. Other times, admins are moving the entire folder all together, rendering the logos' hyperlinks useless (because the logos filepaths are absolute and Autocad can't handle relative paths instead of absolute).
Also, when the logos filepath is very long, Autocad and/or Windows can't handle it right and doesn't show the logos in the dwg.
So, we have to export all drawings again from Revit to dwg, just to rebuild the logos hyperlinks. That's kinda stupid and time consuming. Tekla is embedding logos directly into dwg. That's the only foolproof method to keep the logos right.
I know Autodesk doesn't advice to embed large pictures in Autocad, but what about the logos ? Logos are small and are bitmaps. Revit and Autocad handles bitmaps the same way.
