In your opinion, what is the futur of 2D drafting?

Hi there,
I recently asked myself a lot of questions about the usefulness of 2D in 2022. With the democratization of BIM and the evolution of 3D, I wonder what place does 2D drawing take today? who is it for? and how do you imagine 2D in 10 years?

I know that there are trades which do not necessarily need BIM, and which are content with Autocad, but who are these people? are they many?

Have a lovely week!

I work for an architecture/structural engineering firm.  3D in Architecture and Revit has its place for presentation and analysis of complex projects in the design phase but when it comes down to generating the drawings for permitting and construction they are, for the most part, useless.  2D is necessary for the fully dimensioned plans and details in a project and I don't see that changing.

Then how are all these firms that are using 3D models generating drawings?

 

I couldn't disagree more. "Useless" is a pretty strong word for a lot of work put into, not only the geometric modeling but also adding the information to our models.

 

I can tell you that most are not converting 3D models to 2D drawings. We are annotating and dimensioning 3D models for documentation at the design and fabrication levels. Sure, there are "2D" views of the 3D model but the model itself is still 3D. The information may be presented in a 2D format but definitely still viewing the 3D model.

Drafting is a breeze and Revit doesn't always work the way you think it should.

2D drafting is a dying art. 

 

Tablets and laptops are becoming more and more useful on the job site. Supervisors and foremen are utilizing these devices to access multiple 3D models for clarification and/or additional information not included in the drawing set(s).

 

BIM does not negate the usefulness of AutoCAD. AutoCAD can be a part of the BIM process and will probably continue to be used for 3D modeling. 

 

Using Revit doesn't automatically mean that one is doing BIM. It can be used for spatial coordination without the information aspect.

@safaesouna1 There is no magic single correct answer: as of November 2022 this CAD world of ours (and not just AEC either) still relies on both to "get the job done".

Your question is too broad. That's all.

Multi-discipline A/E firm here. We utilize both 3d and 2d platforms for our projects, and the decision on which one would be better is on a project-by-project basis, with probably 80% company-wide being done in Revit (not including our Civil dept., of course), and we're at about 50% Revit/Autocad in my department.

Ours is typically a somewhat conservative industry, and we're located in a conservative part of the country (meaning we're not the first to jump on new tech, etc., like they would be on the coasts). However, one huge difference that came about in 2021 and has continued into and through 2022 is the more widespread use of the actual model in construction of projects.

Prior to 2021 the models were used mostly for visualization and coordination, etc., with the 2d plan sets being the sole vehicle of use during construction. But 2021 brought on much more emphasis on the use of the actual model during construction, and in a few cases so far is beginning to take the place of drawings... specifically when we'd normally create a new drawing/detail from already existing information, we're seeing more of a directive to "look in the model", instead of creating those additional drawings/details.

So even here it's slowly becoming more common to rely on the models and less on the 2d plan sets.

(edit: For some reason it won't allow me to put empty lines between my paragraphs.. lol)

I think 2d drafting will always have its place. But that usage will be dwindling in the largest parts of the industry, especially as contractors get more and more up to speed on doing all their stuff in/with 3d

2d doesn't mean just Autocad, and 3d doesn't mean just Revit. I know companies that do 3d in Autocad (and have for many years) and some that do 2d in Revit as well. But, especially on small projects (and / or legacy projects), I think 2d cadding will continue to be the tool of choice for many years.

For more than 50% of the drawings, 2D is enough. On site the 're still working with paper plans, so even if you draw in 3D, you need to print 2D views ! So you spend much time to draw in 3D and "yes" you detect clashes (sometimes) and after you print a 2D view.  🐵
