Is there a way to import someone else's project into your own template? I know you can go into a 3D view ang copy & paste, but I was hoping to try a more "professional" approach. I on't like the creator's units, font, titleblocks, methods, etc...
You can automatically move over project standards and some types using the Manage > Transfer Project Standards tool. Just have both project files open in the same session.
For specific component families, you should first [from their project] R > Save As > Library > Family. Save the families you would like to use in your project. Then simply [from your project] Insert > Load Family.
Lastly, you can copy & paste content as another approach. I hope this information helps!
