Every so often, you may still need to get the linework from an AutoCRAPfile to show up in your Revit views. I know. It’s sad, but true.
I am fully in the camp of not needing ACAD to do drafting. I know there are a LOT of folks out there who swear by this process, but I don’t buy it. Time to throw off the crutches, I say!
Once in a blue moon, you may need to get access to ACAD linework in your Revit model. Our rule of thumb is that 99.99% you need to make sure that you are LINKING the .dwg file and not IMPORTING it.
Importing will suck all the linework from the .dwg file and put it into your Revit file, adding each layer as a linetype which can cause chaos and confusion.
Linking the file will give you the classic link “onion skin” effect, where the contents of the .dwg can be seen in your Revit model, but not touched. Changes to the .dwg can be reflected in the link. And you can control the appearance (linetype, lineweight, color) of different layers from the linked .dwg by going to the view’s Visibilit Graphics.
LINK, do not IMPORT your .dwgs and your Revit file will be much happier for it.
Fun fact: Revit even when you link in a .dwg, Revit “imports” the contents of the file into your model, it just keeps it in a nice “quarantine”. This is why a linked .dwg will still appear in your model, even when Revit warns you that it can’t find the .dwg file. It’s also why linking in a .dwg file causes your Revit model to bloat up like me at a donut store!
