Its been a sad day. Every time I hear that a project that has begun to be completed start drifting to AutoCad, I see a funnel with a dead end street going straight to AutoCad. Once you break off part of the Revit workflow to AutoCad, I see a gaping wound that may as well surrended and be all AutoCad.

The benefit of working in Revit is the coordinated nature of the project set. For reasons of limited Revit trained and experienced staff, a principal managing the project I am working on has decided to produce wall sections in AutoCad neairng 50% DD. I see the time invested in getting the Revit model to 50% DD in Revit down the drain.

Exterior details, and curtainwall elevations develop from wall sections. By moving to AutoCad to produce wall sections at 50% DD, I see a project being cut in half. It may as well be all AutoCad if the information being developed in AutoCad is not to be coordinated back to Revit.

Has anyone experienced success with a Revit / AutoCad hybrid project?

On one of our initial projects, we did a split.  As you said, you loose many of the advatages of REVIT and actually create problems in REVIT that were the same as in CAD.

Why would you want to do wall sections in CAD if you have the envelope modeled?  Much easier in REVIT...  

Details in CAD ?  .... maybe if you don't have the staff - That's all !

I agree with WWHUB. If at all possible I try to do everything in the Revit programs. I did a small tenant buildout project completely in Revit and I was able to create every plan, section, and detail except one. The one I had to draw in autocad was an Isometric view and even then I only used Autocad for the lines. I know it is very frustrating not to be able to use the program for the entire project. I have had to deal with that also. Good Luck!

I was able to sell doint the wall sections in Revit. I'm reallyn not the one making the decisions. If I was producing all of the drawings, I would do it all in Revit, but when it comes down to it, not everyone, particularly older more technically skilled architects know Revit.

So yes, its frustrating and its inevitably up to the Revit "evangelists" in each office to sell Revit to  those making the decisions.

This is one of the benefits  of doing an IDP project that is contracted as BIM. You cannot go to Autocad due to the terms of the contract, so you have to solve it in Revit. I have been involved in a few Revit projects that we're abandoned to Autocad...the IDP project was really the one that elevated my firm far into BIM because they had no choice.

 If your firm has an exterior technical architect who is old, maybe he, or she is barley getting by with autocad your in a fix. This is actually a common problem with older staff. Even at a firm like ARUP, there are alot of engineers who can't even cad- they still hand draw everything.

             Having it in the contract really helps push everyone.

Why doesn't reivt have the simple autocad commands that we know and love. [ 1 2 ]
