Some time ago, I used Adobe Reader (the basic one) to view and rotate a 3D model from Autocad. Yes, I know that I can export a Revit model into a DWFX and view it in Design Review, but that requires a ferr Design Review download. Some clients don't have administrator rights, are too lazy, don't have the computer savy to install, etc..., so a PDF 3D model would be nice.


---Is this possible with Revit?

---Is this possible with Autocad?


I have Adobe X Pro where I can enable this if Revit and CAD have the ability to print a 3D PDF.

Being able to convert an Autocad or Revit model to a 3D PDF is so valuable. 3rd party pluging are worthless beacause:

     1)  they need to be installed

     2)  they cost money

     3)  you need administrator priviledges

     4)  time to configure & learn

     5)  clients are not willing to jump through hoops

     6)  fear of installing something new on a company laptop.

With Adobe 9 Extended Pro, it is as easy as:

     1)  exporting from Autocad or Revit to IFC.

     2)  opening up Adobe and importing IFC

     3)  creating PDF and saving

     4)  opening up new PDF and "enabling" so the basic Adobe Reader can have all the "bels & whistles". Then saving again.


I managed to get a copy and it is so worth it and valuable. It's really priceless!!

Just a thought - Bluebeam puts a plug-in right into Revit to create a 3d PDF in 1 click (well 2 if you count saving it).


It works great and I use it all the time and a lot cheaper then Adobe

Image attached showing the plug-in in revit .

If you want the PDF I can email it - too big to put up here.



Since the time I originally wrote this, Bluebeam came out with an add-on to Revit that will create 3D models. I think the problem is solved. It is cheaper than Adobe or Tetra4D...and it doubles as a PDF creator, review, mark-up, and reader. By far, this beats it all

I too would like to see a utility to export to a 3d PDF, but Autodesk seem to just try and push DWF and don't care that 3d PDF is much more universal. I see that Tetra 4D is releasing a 3d pdf converter for Adobe Pro x this month, What I don't understand is the compatibility chart. Does anyone know what tessellation and BREP mean in terms of conversion to 3d PDF?

You used to be able to do this in Revit/AutoCAD, until Autodesk abandoned Open GL in favor of Direct 3D. 


If you have 3ds max there is a work-a-round, for Revit at least. 

1. From Revit export to FBX. 

2. Import that FBX file to 3ds max.

3. Export all that from 3ds max to 3ds (not max). 

4.Open Adobe Pro, drop that 3ds file into the Adobe workspace. 

5. Save your 3D PDF

I called Adobe support and I was told that "Adobe 9 Pro Extended" can import Autocad models but not the latest "Adobe 10 X Pro". Funny though. So I guess I need to go back to my reseller to bitch & moan.Then I can export Revit models to Autocad so Adobe can pick this up.


Can anyone validate this statement?

yes, Adobe are going with a 3rd party plugin (Tetra 4D)  that you will need for Acrobat pro X that will cost you $400. Isn't that nice

Maybe so, but that's version 10 "X Pro". Version 9 "Pro Extended" should do this and it still may be available.


Any confimations?

I do not have Acrobat Pro to verify, but I believe it will open IFC files, correct? I know 9 could -  If so, you can just export your Revit model to IFC to be opened in Acrobat.

Re: 3D PDF

Hi there,


During my online research of CAD users requirements of PDF, I stumbled across this forum and some interesting questions. As CTO at Tetra 4D, and responsible for the roadmap relative to the abilities to support 3D PDF creation questions such as these drive a lot of value relative to the software future direction.


3D PDF Converter for Acrobat X Pro, is the next generation solution for converting 3D CAD data to rich interactive 3D PDF documents. It replaces the capabilities that were available as part of the "Pro Extended" Acrobat 9 product.


With respect to the Autocad products we currently support the IFC format for translation to PDF. 3D PDF Converter also supports, using the native acrobat libraries, DXF, DWG and DWF.


However, Revit is one format that we are very interested in understanding the market need for.

Is this something that would be of value to Revit users?

If so, what would be an acceptable work flow, the author using 3D PDF Converter to create a 3D PDF to send to someone with a free Acrobat Reader, or the ability to send a Revit file to someone with 3D PDF Converter??


If you interested in knowing more about 3D PDF Converter - jump over to

Also - Tessellation is the ability to reduce the polygon count of a model, there by reducing the size of file and increasing visual performance. Obviously it is very complicated, but on the surface you can think of it like compressing a JPG.


B-Rep is a boundary representation of the 3D Definition. It allows the mathematical definition to be defined, associated to the PDF, so that other CAD or CAE system can read in the exact definition.


By having both a tessellated and B-Rep definition, you can create a small file, suitable for high performance visualization, yet still have the mathematical definition, which allows actions like precise measurements to be take of the data.


I hope this helps.
