2D drawings are replaced by 3D models?1/31
Recently I have heard the news that 2D drawings are replaced by 3D models? but I don't accept, It still plays a prominent role in designing the industrial projects and it has its own reasons for it. 2D is the best option to choose when you are facing tight deadline and designs needed are a single component or a single part as basic geometries are easy to generate using 2D CAD tools.We use only 2D drawings for our projects.
2d drawings will never go away,,we will always need shop drawings, and assembly sheets,,cut lists,,ect,,,2d line work will be here forever
I would think that what you heard is more a question of the creation of models/assemblies in a "3D modeling" environment and not the replacement of "2D drawings".
In a "3D modeling" environment, one can define component thicknesses, etc and all the relationships between the various parts that make up an assembly/model - and even make things "parametric" in some applications.
The production of "2D drawings" (assembly and component views) from these "3D models" will always have a place in many areas of engineering and production. So, "2D drawings" are not history.
This may seem like semantics...
What I think will disappear will be 2D Drawings created from scratch, and not derived from a 3D model.
When revision occurs, if the 2D drawings are derived from a 3D model, the integrity of the entire drawing set remains intact. Revisions with 2D only rely on the draftsman to catch all the relationships and update them manually...This will and should go away in my opinion.
Sections are awesome in 3d. Good point Gary.
Doing the original work in 3D parametric makes changes much safer. Revisions for the shop drawings printed in 2D from the 3D model, including the sections are a mouse click away.
And often times now you can have your 2D outputs referenced from the 3D model so when you make a change you make it once in the 3D and then update the reverence model in the 2D shops supplied to the customer. It all gets corrected instantly.
I have utmost respect for those who would have to manually remember to go back and update every elevation and plan veiw, as well as their respective detail and section drawings, manually. I cant even fathom how hard that is/was.
Not everything needs a 3d view, so no 2d drawings will not be replaced by 3d completely.
I can only relate to my experience.
3d can be a tough sell though. Some companies would prefer to use Auto Cad light... convinced of their "beliefs", i.e. group think...
This has been the biggest question posed most often by shop owners and project managers. Probably the biggest misunderstanding is that when a commitment is made to switch to "3D", with every job (cabinets, millwork etc.), data libraries are generated for hardware, materials and machining routines (to name a few). I see so many projects with cascades of changes these days and updating 2D plans and elevations is a huge amount of work - and a major source of layout errors.
Hi Rufus, long time no hear
Do you mean that the model should be modeled from the bottom up?
Thanks that is a good way to do it.
I haven't used SW since 2002+, I'm sure the new version would be mind blowing.
Do you get a single spread sheet from the assembly?
What do you use for cnc data?
Is it possible to get csvs out SW?
We are working with many clients who still needs the drawings in 2D. other type of drafting or designs i.e. 3D modelling is helpful for the analysis. But when it comes to mapping or drawing layouts or architectural plans, 2D drafting is the best option as it gives better ides about layouts. I work with many clients from land surveying industry and they all want drawings in 2D only. have a look at the all sorts of 2d services opted by clients.
There are factors that underlie 2D-3D drafting employment-most of which are centered in business models and project complexities. Unfortunately for the pencil drafters, the day came where they set the pencil down and started CAD or did something else; with the onslaught of automation likewise with CAD-in due time we will be 3D CAM drafters or do something else. Until then, hopefully small business survives!
