When companies are looking for CAD services, one of the first questions they often ask is: which software do you use?
It is a reasonable question. If your team works in Fusion 360, you might assume you need a CAD supplier who also uses Fusion 360. If your factory works in AutoCAD, you might assume your designer needs to work in AutoCAD too.
In most cases, this assumption is incorrect. And understanding why can save you a lot of unnecessary searching.
How Modern CAD Files Actually Work
In modern CAD, the fundamental unit of exchange is not a proprietary file format tied to a specific software package. It is a neutral exchange format that any major CAD platform can read, write, and work with.
The most commonly used exchange formats are STEP (Standard for the Exchange of Product model data) and IGES (Initial Graphics Exchange Specification). Both formats capture the full 3D geometry of a part or assembly in a way that is software-independent.
This means that a model created in SolidWorks can be exported as a STEP file and opened in Fusion 360, Onshape, or any other major CAD platform. A design started in Onshape can be exported and refined in SolidWorks. A 2D drawing produced in AutoCAD can be exported as a DXF or DWG file and opened in virtually any other CAD or drawing tool.
The data transfers. The platform is just the tool used to work with it.
What This Means for You
When you are looking for a CAD supplier, the platform they work in is much less important than the quality of their work and their manufacturing experience. What matters is that they can deliver the files you need, in the format your team or factory requires.
If your team uses Fusion 360, your CAD supplier does not need to use Fusion 360. They need to be able to deliver a STEP file or a Fusion 360-compatible format that your team can work with. If your factory needs DXF drawings, your CAD supplier needs to be able to produce DXF drawings: regardless of which platform they use to create them.
The practical question to ask a CAD supplier is not which software do you use, but what formats can you deliver: and can you demonstrate that your deliverables are compatible with my workflow?
When Platform Does Matter
There are situations where the specific platform used is relevant. If you are looking for a CAD partner to work directly inside your team’s shared environment: for example, contributing to a shared Onshape workspace or working within a specific PLM system: then platform compatibility becomes a real requirement.
Similarly, if you are using parametric design features or complex assemblies that rely on specific software functionality, there may be cases where a STEP file does not capture everything you need without some rework at the other end.
These are real but relatively narrow cases. For the majority of product development and CAD support work, platform compatibility is not the constraint it is often assumed to be.
How Pro-Dev Handles This
Our CAD team is experienced across SolidWorks, Onshape, Fusion 360, AutoCAD, and other platforms. We work with clients in whatever format their workflow requires, and we deliver files in STEP, IGES, DXF, DWG, PDF, and native formats as needed.
If you are a manufacturer working in AutoCAD and want to see what your product would look like as a 3D model, we can build it and deliver it in a format your team can open. If you are an engineering firm that works in SolidWorks and needs overflow capacity, we can work within your file structure. If you simply need a set of drawings and do not care about the software, we handle that too.
The platform is not the barrier. Reach out and we will work out what format your project needs.
