AutoCAD 2010 and Revit Architecture

gator to revit_1Your probably wondering why I'm writing about AutoCAD 2010 on a Revit blog. It's a valid point. Well the Autodesk 2010 portfolio was announced last  Friday with fanfare and a global webcast. If you haven't seen it, its worth taking a look, because you'd get a sneak peak of Revit Architecture 2010 as well as the rest of the new 2010 Autodesk AEC portfolio. :-). If you haven't take a look here.

I've been fortunate enough to have had the AutoCAD 2010 beta version on my laptop for sometime now and I have to say I have been very impressed with what's new. There are some cracking features in this release and the Revit development guys should take note, because there are some nice touches which should be in Revit!! If you want a complete run down of all the new features in AutoCAD 2010 take a look at Heidi Hewetts video examples, which can be found here.


Ok, I have to say that I haven't really used AutoCAD in anger for a number of years. I generally use it now as a translation tool which sits along side Revit. AutoCAD is still a very powerful tool, even if its still just considered a CAD programme that draws lines arcs and circles by some. Saying that, anybody who attended the design symposium session on the Monday at AU 2008 you may have a different view! I generally don't get that excited about using AutoCAD, but I have to say, that this is the first version that has made me smile whilst using it.

So what will AutoCAD 2010 mean for the Revit user? Fundamentally in my view, the most important feature is the introduction of freeform modelling within AutoCAD. As many of you have seen, Revit Architecture 2010's freeform capabilities have been completely overhauled as well. With both AutoCAD and Revit now having these sort of capabilities this will only enhance the tools available to the design architect.

And the reason why I believe this is the case?

Convert to solid! This tool alone will change your workflow for ever.


It will mean that you can create complex forms in AutoCAD as meshes, convert them to a solids, save the file and then load this into a Revit mass family. Then use the building maker tools, convert this into building components. This is nothing new, as you've always been able to do this workflow from AutoCAD, but the ability to work with a mesh inside AutoCAD and convert these meshes to solids, completes the weak link in this workflow. There have been others ways to achieve this, but you had to resort to third party applications to do the translation. Now its all in the same box.

Take a look at this example............

I quickly did this pancake shape in AutoCAD 2010 using the new mesh tools and then converted to solid and saved the DWG.


I then imported this DWG into a mass family and then loaded this into a project. I was then able to skin the mass with walls and curtain wall as well as get the area of the floors plates.

Ok, it won't win any awards but as a quick design exercise, this is just amazing.On a side note this form was brought into Revit Architecture 2009 and it only took me 30 minutes from inception in AutoCAD until completed renders in Revit.

Hi David! This is very interesting. May I link to your blog? By the way, I am Revit Bimmer - revitbimmer.blogspot.com.

Last comment today, I promise. Okay, alright, I just need to use Autocad 2010 and "Convert to Solid" to generate useful 3d masses that can be used in Revit. My head is revited today. TGIF.

Thank you for giving me hope for someway to generate dumb mass models for use in Revit. If you could answer the million pound question, can you import a Sketchup dumb box into Autocad 2010 and spit out a mesh that can be imported into Revit? Sorry for so many questions, I am quite desperate and mad to understand how to use 3d masses in Revit.

HI! I am a beginner. Starting building design school this coming semester. I want to start teaching myself how to use autocad (as I'm slow at tech stuff and need to practice a lot to get anywhere).
My question is- do I need both autocad and Revit? can I just skip straight to Revit if I've never done any computer design ever?
I tried finding info online but there doesn't seem to be anything re the relationship between the two.
Any info would be a big help.

I made a model in sketchup, exported it to cad in .dxf format. Then i imported it to revit 09 in dxf format. Created a mass out of it. but im not able to paint the surfaces at all. Any help?
