CONTROLLING THE VISIBILITY AND GRAPHICS OF A LINKED DWG IN REVIT

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.
