Search intent around Fusion 360 SolidWorks import is usually pretty specific: someone has a .sldprt or .sldasm file, they are already sitting in Fusion, and they do not want to break concentration by bouncing out to a separate export chain.
The CADExchange Fusion add-in is built for that exact moment. It adds a native Fusion command that signs into your CADExchange account, uploads the SolidWorks source, tracks the conversion, downloads the STEP result, and inserts it into the active design.
1. What the Fusion Add-In Actually Changes
The main value is not just file conversion. It is the fact that the whole workflow stays inside Fusion: sign in, pick the file, attach references if needed, convert, and insert. That is much cleaner than manually exporting, downloading, and importing with no visibility into entitlement or monthly usage.
2. Supported Workflow
- Install the Fusion 360 add-in.
- Open Solid > Insert > Insert SolidWorks File via CADExchange.
- Sign in with your CADExchange account.
- Select a .sldprt or .sldasm file.
- Attach a support ZIP when the source is an assembly.
- Click Convert and Insert.
3. Why Assemblies Need More Care
Single parts are usually straightforward. Assemblies are where import workflows break down, because a top-level .sldasm references other parts and subassemblies. If those referenced files are not packaged correctly, the converter may fail or return an incomplete result.
If assembly work is the main use case, go straight to the Fusion 360 SLDASM import guide.
4. Included Usage Inside Fusion
The add-in uses the plugin API bucket for fusion_addin clients. That means the usage story is separate from generic browser uploads: CADExchange Pro is $10.00/year and includes 60 Fusion conversions per month before wallet credits kick in.
If pricing is the main decision point, read the Fusion add-in pricing guide.
5. When This Workflow Makes the Most Sense
- You already work in Fusion all day and want SolidWorks import to feel native.
- You need a repeatable team workflow with one account, one billing story, and one conversion backend.
- You often receive supplier parts or archived SolidWorks models and need them inserted quickly.
