Jeremy shows how you can review a DWG file to determine if the source entities were Text or Labels in Revit. This principle extends further, as he describes:
The differing TypedValue 11 is consistently -2000300 for a text and -2000280 for a label element. What does this mean? Well, is actually quite easy. On seeing these large negative numbers in this specific range, an experienced Revit developer will quickly suspect built-in category or parameter enumeration values. You can check what they actually represent in the Visual Studio debugger, by jumping to the definition of these enumerations and searching for the specific values. Looking back at an ancient blog post on the DWG and DXF export Xdata specification confirms that these numbers do indeed represent the built-in category of the source element and thus can be used to distinguish the two.
You may have noticed that when you export a DWG file, Revit temporarily creates PAT files in the export folder, and then it deletes them, just leaving DWG and PCP files.
To recover the deleted PAT files, you can simply use the program Recuva!
I’m not sure how well this works for network shares or NAS devices, but it should definitely work if you export the DWG to a local drive and immediately recover the PAT files (before doing anything else).
From IMAGINiT Technologies Support Blog: We can add a modifier to the export dialog box for the items we want to adjust, make sure that you also do this to the sub-categories of the element also, and select the Phase Created modifier and add it to the list, in the separator space, add the separator type you want to use…this will give us something similar to the following in the cad file: A-DOOR-Existing
A well known limitation of current Revit versions is that you cannot easily transfer a Legend View between projects.
However, you can do the following with Legend Views:
Save to Project as Image (just right-click on the Legend View in the Project Browser – you will probably have to open or activate the view before this command will ungray itself)
Export the View as an Image
Export the View as a DWG
If you are going to export the view as an Image, I recommend a minimum DPI setting of 150. You can then import this image to another file. If you Save to Project as Image, you can just copy-paste the image between open projects, or use the Save to New File command on the actual Rendering view itself. Obviously, you need to manually update this image whenever the Legend changes.
If you Export as a DWG, you could then Link that DWG into other projects. When you want to globally update the Legend View, you could re-export the Legend from the original RVT project and over-write the Legend DWG you exported and linked earlier. You would probably have to tweak the visibility settings a bit to make this Legend-export-link method to work effectively.
