Converting PDF to CAD has become an integral part of CAD designing for design technicians over the years, and we’ve really come to appreciate the simple ability to convert PDF files to either a 2D or 3D CAD file.
You’ll find that converting a PDF to a CAD file helps a lot when we’re under a tight schedule and takes some of the design burdens off our shoulders, making the design process a whole lot easier.

Why’s This Conversion Necessary
We’ve established earlier that PDF to CAD conversion makes the design process a lot easier and builds an effective collaboration between designers in various locations.
Seeing that the need for downloading really-large files are completely eliminated, PDF files can be easily shared either with clients or with colleagues and designers can be certain that the integrity of their designs remain intact because they cannot be altered in this file format.
Converting your designs to PDFs makes it really easy for CAD developers to upload their designs online and also makes it easier for us to have a sample of your work that can either be viewed in our phones without the need for a hard drive.
PDFs became the preferred format for this conversion because of how well the data transferred through them is displayed the same way across any device. Having a PDF become even handier when the original CAD design is misplaced or isn’t readily available.
Almost every computer can access Portable Document Formats and because PDFs cannot be easily edited and were carefully designed to display both raster and vector graphics uniformly across all devices, it became the best option when the need to convert CAD designs became necessary.
First Things First
Before we delve deeper, we’d first need to understand that in converting PDFs to CAD, we simply convert the PDF file into the native file format of whatever CAD software you’re using and in case you don’t have any, you should checkout SolidFace, it’s a rising star in the CAD world.
Converting CAD to PDF
It’s no longer news that we can easily convert our 2D or 3D drawings to PDFs, and the best way of achieving this has always been with the use of the CAD software installed on your computer. But just in case you don’t have any, there are a lot of online CAD conversion tools that would make this conversion effortlessly and some of them might even send the converted file to your email.
But there are so many conversion tools out there that it might be quite difficult to find the right one for you. Just bear in mind that your preferred converter must be able to provide extra layers of security by applying watermarks over your designs, it should also allow you to add a password over your PDF so that nobody can access your file if they don’t have a password.
Check out this great guide that will show you everything involved in converting from CAD to PDF.
What Your PDF Might Contain
Let’s take a look at what a regular PDF file with CAD designs will contain in its pages:
- It might contain some texts spread across the page.
- It might contain several 2D or 3D designs although it’s worth noting that we obtain a better result when we convert 2D designs to CAD.
- The PDF might also contain several vector or raster images.
When Converting PDF to CAD, Look Out for These
After carrying out the conversion, PDFs, in general, begin to display some unwanted traits like an inability to accurately transform curves and arcs into CAD arcs. So any circle in a PDF file is usually represented as short circular interconnecting lines. Trust me; you do not want to have this happen to you at any point in your design because you’d have to create them all from scratch.
Despite the fact that a raster image will display uniformly across all devices when it’s converted to a PDF file, it doesn’t always maintain that uniformity when it’s converted back to a CAD format. So you have to keep your eyes open and use a great converter if you don’t have any CAD software.
In converting PDF files to CAD, you’ll not only need to worry about your circles and arcs being misrepresented, because line width and line type is something that also gets misrepresented when we try to convert. More than half the times, lines will end up thinner than expected, longer or shorter than indicated by the PDF file and so it’s really important to crosscheck the converted file once your conversion is complete.
Working with texts also become tricky in your newly converted CAD design –mostly if you didn’t use a top-notch converter– because the texts in the PDF might not be accurately reassembled and you’ll either end up with words that split at the wrong place or words that don’t make much sense.
Converting PDF to CAD
The two methods that clearly stand out when it comes to converting PDF to CAD is:
The Manual Tracing method where you use any software of your choosing to trace out all the lines, the shapes and also every single text you want to convert into a vector image.
Sadly, I’ve tried it once, and it’s safe to say this tedious method should only be used when you’re really desperate and don’t have access to any CAD software or online converters.
The Automatic Tracing method takes the stress of manually tracing the PDF off your shoulders. Instead, these conversion softwares quickly detects the lines, edges, texts, does the tracing and under a few seconds, it converts your PDF into a vector image that can then be saved as a DXF (Drawing Exchange Format) which can then be opened by any CAD software of your choice.
When using online converters, its best to consider the security standing of that site to avoid granting access to malware.
There are a lot of online converters out there and it might be quite a hassle to get the right one for you. So here are a few online PDF to CAD converters that’ll get the job done flawlessly.

What’s the Best PDF to CAD Converter?
It’s also preferable to use SolidFace for all your conversions. It offers great support and coverage for a whole lot of CAD formats.
It’s true that there are lots of converters out there, and in a case where you’re in a situation where your CAD software isn’t close and you need to convert a PDF fast, you can find great converters both online and offline.
Although some are paid and others are free, whatever converter you intend to choose must be able to recognize and reassemble text accurately, it must possess vector and raster image editing so you can improve the quality of your PDF before converting.
Don’t also forget to use a converter that can deliver true CAD arcs. You do not want to spend your whole day recreating those arcs and curves. As an aside, your ideal converter must also support multi-page PDFs and batch conversions.
Are PDF to CAD Conversions only for Architectural Designs?
No. PDF to CAD conversions can find lots of applications with PDFs containing electrical designs, piping systems, mechanical parts design, it even works excellently well for maps and sketches.
But it appears to be a lot easier to convert a PDF file with 2D architectural designs to a CAD format. From here, the architect could decide to make it a 3D design.
Is it Possible to Convert 3D PDF to CAD?
Normally, CAD technicians would rather work with 2D PDF files and convert them to a CAD format of their choice, because the process of converting 3D PDFs to CAD involves a lot of sketching. This means that the PDFs 3D drawing needs to be fully dimensioned.
It is indeed possible to convert 3D PDFs to CAD, but it can only be done with the use of special 3D PDF converters. One of them being: Tetra4D. With the Tetra4D software, you can be able to create a 3D PDF that is secure and supports full 3D interaction. But the major catch with this is that you’ll have to use Tetra4D while creating the 3D PDF and also while converting the 3D PDF to CAD.
Can 2D converters also Convert 3D PDFs to CAD?
Although there are several online and offline 2D to CAD converters out there, most of them don’t give us the result we want when we try to use them for 3D to CAD conversions because all 3D designs have with a lot of intricacies and peculiarities that complicates the conversion process and so is impossible for 2D converters to capture.
