It is not possible to place external drawings from your BIMcloud library, unless they are objects.
Recommended workflow here would be:
1. Place external drawings with File / External Content / Place External Drawing... command.
2. When you placed the drawing, select it and on the info box (under update type) / in the settings dialog (Identification part, on the bottom after update types), check the option called "Store in the Project".
This command will save your drawings to the project, so other users will be able to see it as well. On the other hand, it is likely that your project size will significantly grow because of stored drawings.
