Free CAD Projects – 3D Models & 2D Drawings
Free CAD projects taken from real machine designs, not classroom exercises: a belt conveyor, a mobile gantry crane, a ball screw actuator and six more. Each download includes the editable 3D model and 2D production drawings, so you can study how a working design is modeled and documented, practice on it, or build it.

CAD Practice Projects from Real Machine Designs
Most CAD projects for beginners are simple brackets and blocks. These are complete designs that were made to be built, so they show the things tutorials skip: how an assembly is structured, how weldments and standard parts are handled, how fits and clearances are chosen, and how a full drawing set with a bill of materials is laid out. Open the model, rebuild a part yourself, then compare your result with the original.
Free CAD Projects for Students: a Suggested Learning Path
If you are using student CAD projects to learn, work through them roughly in this order:
- Single parts and small assemblies: the snap-off knife, the load binder hook and the laser sensor mount. Good for part modeling, sketches and simple drawings.
- Mechanisms: the ball screw gripper drive, the rotary separator and the scissor sling. Good for constraints, motion and how moving parts are assembled.
- Complete machines: the belt conveyor with drive and control box, the A-frame gantry crane and the display stand with removable baskets. Good for large assemblies, frames and full production drawing sets.
Free CAD Project Download: What You Get
Each free project comes as a Free Complete Pack: the full 3D package and the full 2D manufacturing package, the same documentation structure as the paid projects. The 3D files are native Autodesk Inventor assemblies with STEP export, and the 2D drawings come as DWG and PDF. Check the 3D model license for how the files may be used.
3D CAD Projects You Can Open in Any CAD System
You do not need Inventor to use these free 3D CAD models. The STEP files open in Fusion 360, SolidWorks, FreeCAD, Solid Edge and most other CAD systems, and the DWG drawings open in AutoCAD, DraftSight and other 2D CAD programs. Working with a model from another system is also good practice in itself: you learn how imported geometry behaves and how to rebuild features around it.
From a Free Project to a Full Build
The free projects show the same modeling and drawing quality as the full catalog. When you are ready for a larger build, see the crane CAD plans, hydraulic press plans, welding jig plans or all DIY workshop equipment plans.
