By clicking Service Packs and Fixes, then Revit Products, I discovered this little gem:

Autodesk CAD- and BIM- Standard Tool for Revit | Revit Products | Autodesk Knowledge Network
The tool provides extended functionalities of DWG and DXF export in addition to Revit´s “out of the box” Export. Some examples are:

  • Define *.dwt template for export
  • Implement layer standard
  • Assign objects and components (e.g. wall layers) to AutoCAD layers
  • Include material information automatically to layer names
  • Assign categories, families and even types to AutoCAD layers
  • Create blocks with attributes from tags
  • Replace tags or symbols by pre-defined blocks with in the *.dwt template
  • Process doors and windows with ÖNORM tags to DWG

There is also the ability to convert polylines from DWG files linked to a Revit project to space boundaries and rooms.

I thought I got in a loop today:

  1. Export DWG
  2. Expand All
  3. Select all rows
  4. Try to delete the number in the Color ID box
  5. This warning will come up:

You have to press Close for every selected row (could be hundreds) – quickest way is to hold down the Enter key until the warning goes away.

Originally I thought this was a looping bug, but it is just Revit being overly thorough 🙂

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.

The Building Coder: DWG Issues and Various Other Updates

I previously posted a way to generate PAT files from an exported DWG file.  One of the comments to that post gives a great alternative method – so unique it actually made me smile.

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).

Pretty tricky huh?

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

Revit au Quotidien has picked up a few mildly scary issues when exporting to DWG from Revit 2013, one seems to be related to dimensions with Text Below, the other to EQ display of actual dimensions.

Have you been experiencing any of these issues?

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:

  1. 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)
  2. Export the View as an Image
  3. 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.

Hope some of these ideas are useful to you!

You can make certain layers export as non printable layers when exporting from Revit 2012 to AutoCAD DWG or DXF files.

First, you need to set the following checkbox in the Modify DWG/DXF Export Setup dialog box:

Make layers containing the following text non plottable NPLT

Then, make a line style and map its layer to a layer name containing the text ‘NPLT’:

After the file has been exported, you will see that the layer has been set to non printable in the AutoCAD Layer Manager:
