Linking DWGs is appropriate where external consultant information must be incorporated into drawings produced from Revit.

All external CAD references should be Linked, never Loaded.

LINKING DWGS

1. Open Revit and select the desired View you wish to link the DWG into.
   
2. From the Ribbon, click Insert > Link CAD
   
3. From the Link CAD Formats dialogue, select the DWG. Note: Only use the Current View option if you have no intentions of viewing the DWG in other views.
   
   Review the linking options and click OK.
4. The DWG will be linked into the Revit file. Note: If the DWG is not visible in the view then reopen the DWG in AutoCAD, ensure that all layers are visible and unfreeze any if required. Remove any unnecessary lines, hatching, annotation and blocks and then perform a purge and audit of the file. Save it and perform the steps above again.

CONTROLING VISBILITY AND GRAPHICS

1. From the View select Properties > Graphics > Visibility/Graphics Overrides click Edit.
   
2. Within the Visibility/Graphics Overrides dialogue, navigate to the Imported Categories tab. Click on the DWG Plus (+) button to expand the Categories.
   
   
3. Select the appropriate categories and click Override. Note: DWG layers are translated to Revit Categories.
   
4. Within the Line Graphics dialogue, select the desired weight, colour and pattern. Click OK.
   
5. Within the Visibility/Graphics Overrides dialogue select the appropriate categories. Click the Visibility Tick button to turn them off. Click OK.
   
6. Check that the DWG graphics have been overridden as expected. Note: Layer conventions and usage must be strictly followed in CAD software to ensure graphic overrides behave as expected.

ADDITONAL NOTES

1. Utilising View Templates is an efficient method for controlling DWG overrides in multiple views. This is an identical method to controlling native Revit model elements, such as Doors.
2. Do no use Override Graphics in View functionality to control visibility or graphics.

In an ideal world, no one would use CAD, ever. Sadly, we don’t live in that world yet so we have to deal with consultants and friends that send us CAD files we have to integrate in Revit. A lot of people don’t really know what they are doing when they import CAD into Revit, resulting in chaos and poor management. Following these tips should help you avoid a lot of problems.

1- PREPARE CAD FILES

Any CAD files linked into Revit must follow a careful process:

1- Bind XRefs: Xrefs can cause problems. Open the Xref dialog box and bind them all, preventing duplicate layers.

2- Run "Purge": This removes unused layers, linetypes, blocks, etc.

3- Run "Setbylayer": All lines settings should be set to layers, ignoring any color, linetype or lineweight overrides. Use the Setbylayer command to quickly resolve this problem.

4- Freeze Useless Layers: Freeze all layers not required in Revit.

5- Save A Copy: Keep the original DWG file just in case. Save the modified file in a Revit "CAD Links" subfolder.

2- USE LINK CAD, NOT IMPORT CAD

Now that your DWG file is ready, you can bring it to Revit. You will notice that there is two options to bring the DWG file: Import and Link. Avoid using Import CAD. It makes your model heavier, causing performance issues. Link CAD is better: it loads the latest version of the DWG each time you open Revit and is more efficient to manage the files.

3- USE THESE LINKED CAD FILES SETTINGS

You have many settings to adjust when linking a DWG file. Use the settings below for the best results:

Activate Current View Only: If left unchecked, the DWG file will appear in all views of the model. In most cases, it is better to import to a single view only.

Colors: Black and White: The default setting is Colors, but you should change that to Black and White. It provides better visibility.

Layers: Visible: By default, all CAD layers will be imported. Set the option to Visible, which means layers that are hidden or frozen in AutoCAD won't be imported.

Positioning: The best way to position DWG file is usually to use Manual - Center option. The Auto - Origin to Origin can also be useful if the CAD file is synched with the Revit model.

4- USE QUERY TOOL TO HIDE CAD LAYERS

Select a DWG file inside your Revit Model. In the contextual tab, you will find the Query tool. Click a line inside the DWG, then use Hide or Delete to make the layer invisible.
