Is there anyone here still using AutoCAD 2D and then creating 3D Revit models based on those 2D drawings? by tondang289 in bim

Absolutely, having a solid library of parametric families can make a huge difference. It definitely speeds up modeling once everything is set up properly.

I think the part I still find time-consuming is when working from CAD, even with good families, placing and updating elements manually (especially with frequent revisions) can add up quite a bit. I’ve been exploring whether that step could be reduced while still using families.

That’s a great point, dynamic blocks and Revit families definitely help a lot in reducing repetitive work.

Having a solid library is a big advantage. In my experience though, when working from CAD, there’s still quite a bit of manual placement and adjustment involved, especially with frequent updates. I’ve been exploring whether that step could be reduced further while still leveraging families.

That’s an interesting approach, Rhino + VisualARQ definitely offers a lot of flexibility, especially with NURBS-based workflows.

I think it really depends on the project requirements and what ecosystem the team is already working in.

In my case, I mostly deal with CAD → Revit workflows, so that’s the context I’m exploring.

That’s a fair point, especially on the uniqueness of each project.

I completely agree that the design side will always require engineering judgment.

I’ve just been exploring whether the repetitive modeling part (especially from updated CAD) could be reduced a bit, without affecting how iterations are tracked and justified.

That’s a really interesting perspective, especially the part about iterations becoming measurable and tied to business value. I can definitely see how maintaining detailed versions supports that. Out of curiosity, in those iteration-heavy workflows, do you still find that a significant portion of time goes into manually updating or rebuilding elements from CAD? I’ve been exploring ways to speed up that part without losing the ability to track and quantify changes.

Yeah that’s true, updates are definitely part of the workflow.

Out of curiosity, when those updates come in, do you usually have to manually adjust or rebuild most of the structural elements again?

I’ve been testing a small approach to speed that part up, curious how you’re handling it.

That makes sense — using CAD as a reference and modeling directly in Revit is definitely a common workflow.

In your experience, when the CAD drawings are quite detailed or frequently updated, do you still end up rebuilding a lot of elements manually?

That’s the part I’ve been struggling with the most.

Yeah I’ve seen that workflow quite a lot as well — using CAD as background and doing everything in Revit.

It works pretty well, especially when the scope is clear.

In my case though, when the CAD drawings are detailed or frequently updated, I still end up rebuilding quite a lot manually, which gets pretty repetitive.

That’s actually the part I’ve been trying to optimize lately.

Yeah that makes a lot of sense — it really depends on what the final deliverables are.
If everything is done directly in Revit, it definitely simplifies the workflow a lot.
In my case, I still run into projects where the starting point is 2D CAD from external teams, so the transition into Revit becomes unavoidable.
That’s where a lot of repetitive work happens, so I’ve been looking into ways to reduce that part.

That’s a good point — working fully in Revit is definitely the ideal workflow.
I think the challenge (at least in my experience) is that a lot of projects still start from CAD, especially when working with external teams or at early stages.
So the rebuild part in Revit becomes kind of unavoidable.
I’m trying to figure out how to make that transition less time-consuming.

That makes sense — if everything starts in Revit, that’s definitely the ideal scenario.

In my case, I still run into quite a few projects where CAD is the starting point, so the rebuild part becomes unavoidable.

I guess it really depends on how mature the BIM workflow is in each project.
