Collaboration for Revit and autocad files

Everyone should know that the optimal number of DWG files in your Revit project is less than 1. That being said, it is quite often unavoidable to link dwg files in your Revit project files.

It has been said many times over that you should never import DWG files. Technically linking DWG files is only marginally better than importing DWG files. That is because Revit will 'import' a DWG files if you link it. The only difference is that you will be able to: Reload from, Reload, Unload Import and remove the linked DWG file.

When you want to link in a DWG file you may only do this from a local or network drive. You can't link to the A360 team site. (or any other internet site) If you are working on a Collaboration for Revit project you can link DWG files just like you would normally. Your collaborating team members may get to see a dialogue box when they open the project telling them Revit can't find the linked DWG file.

Consider the following setup. Create a separate Revit project file which you will us to link the DWG files you need. Be sure to link the dwg files with current view only and be sure to place the DWG file on the correct view. After you have done so initiate Collaboration for Revit. This RVT file now gets uploaded with all the DWG files in it. If you link this RVT file into another project file you can make the DWG files visible. (It's good practise to place a linked RVT files on specific workset. I have placed this link on a workset called LINK_DWG) You or any of your collaborating partners will not get the warning: can't find linked DWG files.
To make the DWG files from the linked RVT file visible in the Host file you have to do the following.
Open the view in which you would like to see the DWG file from the linked file. Go to visibility and graphics --> Revit links --> Basics --> set to custom --> and set the linked view.
( in the image you see that I am linking to the view 15-level. Later I realised that it might be better to name the view after the DWG file that I have placed upon it)
Next go to the Import categories and check the DWG file that you want to see

If you click on the plus sign you will be able to turn of layers or apply overrides

The additional benefit of this is that all the main Revit project files stay clean of DWG links / imports. This is good for performance.
If you place the linked RVT file with all the DWG files in it on a specific workset than it's also easy to not load this when you are opening the project by simple not opening this workset. This is good for performance.
If you are collaborating with other companies than you can share the DWG information without you having to send them the DWG files separately.

If you want to have a look at the file send me email and I'll invite you to my hub.
