Is It Possible to Convert a 2D CAD Drawing to a 3D BIM File?

Yes it is! 

2D_to_3D_ConversionLet’s talk first about just what it means to go from 2D CAD to 3D BIM.  A 2D CAD file is generated using lines in layers and if you draw  plans, elevations, and sections in a traditional CAD application (like AutoCAD, for instance)  and need to make any design changes, you have change each sheet manually.   

 BIM software addresses this problem by letting the user draw objects (for instance “walls”), instead of just symbolic 2D lines that represent walls.  By designing this way, the building is 'virtually constructed', in 3D with material information and sometimes even the cost of building materials built in.  When it comes to making a design change, you change the object, and the software does all of the relevant revisions automatically.   So, if you change the position of a window in the wall, all of the plans, sections, and elevations change accordingly. 

So, what do you do when you have 2D CAD files that you want to incorporate into your 3D BIM files?

2D to 3D Conversion Technology

2D to 3D conversion technology exists, but the problem is that most design and build firms are focused on current projects that affect the bottom line today, leaving little time for architects and designers to convert 2D CAD legacy drawings into new 3D BIM formats.   Yet some design and build firms are not only accomplishing the conversion of their 2D CAD drawings, but are also excelling in top-line and bottom-line measures with today’s projects. 

How are they accomplishing this? 

Most 3D modeling systems offer features that help manage the accuracy and completeness of 2D to 3D conversion. However, the accuracy of conversion seems to be of major concern, and generally requires hands on time for QC and some manual change.  Therefore, many design and build firms have discovered that outsourcing their 2D to 3D conversion of legacy drawings can insure accuracy, while helping them to make the most of their design staff and saving money in the process.  Often the ROI of outsourcing far outweighs the loss of productivity occurred when using their own staff.

Successful outsource projects always start with a qualified outsourcing firm.  Look for a firm that employs  professional engineers and architects that are qualified to perform any 2D - 3D conversion, whether an architectural 2D - 3D conversion, or a manufacturing drawing 2D - 3D conversion.  Look for a firm that is able to convert hardcopy documents into any 3D CAD program such as Revit, Solid Works, Catia, or other 3D programs, as well as being able to convert 2D CAD drawings into 3D BIM.   Using an outsource conversion firm that is familiar with all aspects of conversion helps to ensure that they are professionals and that your job will be done right. 

Finally, make sure that they are willing and able to perform the 2D to 3D conversion according to your specifications and that they guarantee results.

Convert 2D to 3D

2D drawings are quickly fading away as a memory of the past in the modern design world. The upside of the 3D model provides many more opportunities and advantages and is the staple moving forward in industry today. While some companies will still have some remnants of days past with some 2D CAD designs still in their systems, the technology, and the pace that it moves going forward, will make 3D Cad design the standard. This is why it makes sense to update your system using the Cad conversion service to ensure you do not get left behind in the technological times.
Another advantage to upgrading is that if you have a 3D model of your product, that very same 3D model can be used in the manufacturing process during production. When it comes to deciding on whether to upgrade or not, you should also know that the visual concept that solid modeling provides during the concept of new products will be extremely useful in rapid prototyping of your product.

The most sought after service in the engineering industry is 2D to 3D Cad conversion. This conversion can help you use images for slides, view masters, anaglyphs, forms of stereo viewing, and polarized stereo presentations.
The 2D to 3D Cad conversion then conforms to all aspects of the project such ll the way down to the constructed as fitted status. The conversion services are there to assist you into converting the older 2D models into solid 3D models. Models can come in a variety of file formats and can be converted using any Cad conversion software.
Some of the advantages of using 2D to 3D Cad conversion services are that the dimensions are shown using a separate layer to show dimensions, and block fixture entities to allow for more detailed visuals. All of the latest standards are utilized help develop Cad projects during the conversion process. These capabilities allow the execution of 3D projects to be completed using a vast system of applications and software.
When you go throughout with the Cad conversion to the upgraded 3D version, you are essentially enabling yourself to store all of your files in a much more efficient and organized system. At the same time you will have much more flexibility and increased productivity. This will also ensure you stability of consistence and quality.
