Solidworks vs Fusion 360: Key Differences and When to Use Each

Solidworks is a powerful, professional-grade CAD software mainly used for complex mechanical design with strong offline capabilities, while Fusion 360 is a cloud-based CAD/CAM tool that integrates design, engineering, and manufacturing workflows with easier collaboration. Solidworks suits large companies needing advanced features, whereas Fusion 360 is ideal for startups and hobbyists seeking flexibility and cloud access.

Quick Comparison

Here is a quick side-by-side comparison of Solidworks and Fusion 360 based on key factors.

Feature	Solidworks	Fusion 360
Platform	Desktop (Windows)	Cloud-based with desktop app
Pricing Model	Subscription, higher cost	Subscription, more affordable
User Level	Professional engineers	Hobbyists to professionals
Collaboration	Limited cloud tools	Strong cloud collaboration
CAM Integration	Separate modules	Built-in CAM and simulation
Offline Access	Full offline use	Requires internet for full features

Key Differences

Solidworks is a mature CAD software focused on detailed mechanical design and engineering. It runs primarily on Windows desktops and offers extensive offline capabilities, making it reliable for large projects without internet dependency. Its interface and tools are designed for professional engineers who need advanced simulation, detailed assemblies, and precise control.

Fusion 360 is a modern, cloud-based CAD/CAM platform that combines design, engineering, and manufacturing in one tool. It supports real-time collaboration through the cloud, allowing teams to work together easily from anywhere. Fusion 360 also integrates CAM and simulation features directly, which simplifies workflows for product development and manufacturing.

While Solidworks requires separate add-ons for CAM and simulation, Fusion 360 includes these features natively. Fusion 360’s subscription pricing is generally more accessible for startups and hobbyists, whereas Solidworks targets larger companies with a higher cost and more complex licensing.

Code Comparison

Here is how you create a simple 3D box model in Solidworks using its API (VBA):

vba

Sub CreateBox()
    Dim swApp As Object
    Dim Part As Object
    Dim boolstatus As Boolean
    Dim longstatus As Long, longwarnings As Long

    Set swApp = Application.SldWorks
    Set Part = swApp.NewPart

    boolstatus = Part.Extension.SelectByID2("Front Plane", "PLANE", 0, 0, 0, False, 0, Nothing, 0)
    Part.SketchManager.InsertSketch True
    Part.SketchManager.CreateCenterRectangle 0, 0, 0, 0.05, 0.05, 0
    Part.FeatureManager.FeatureExtrusion2 True, False, False, 0, 0, 0.1, 0.1, False, False, False, False, 0, 0, False, False, False, False, True, True, True, 0, 0, False
    Part.ClearSelection2 True
End Sub

Output

Creates a 100mm x 100mm x 100mm box in Solidworks

Fusion 360 Equivalent

Here is how you create the same 3D box model in Fusion 360 using its Python API:

python

import adsk.core, adsk.fusion, adsk.cam, traceback

def run(context):
    app = adsk.core.Application.get()
    ui = app.userInterface
    try:
        design = app.activeProduct
        rootComp = design.rootComponent

        sketches = rootComp.sketches
        xyPlane = rootComp.xYConstructionPlane
        sketch = sketches.add(xyPlane)

        rect = sketch.sketchCurves.sketchLines.addCenterPointRectangle(adsk.core.Point3D.create(0, 0, 0), adsk.core.Point3D.create(5, 5, 0))

        prof = sketch.profiles.item(0)

        extrudes = rootComp.features.extrudeFeatures
        extInput = extrudes.createInput(prof, adsk.fusion.FeatureOperations.NewBodyFeatureOperation)
        distance = adsk.core.ValueInput.createByReal(10)
        extInput.setDistanceExtent(False, distance)
        extrude = extrudes.add(extInput)

    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Output

Creates a 100mm x 100mm x 100mm box in Fusion 360
