Create basic assemblies or go big with fully defined and documented models containing thousands of parts.

Quickly define relationships between parts using a variety of constraints to build your design.

Leverage patterns for repetitive tasks like fastener insertion or even core design components. Create mirror features that result in other-handed versions of parts or assemblies.

Combine several parts into a single body, subtract a model from a blank to create a mold, and more.

Replace a component with another automatically with options to skip instances.

Make exploded views for documentation and even interactive assembly/disassembly guides using 3D PDF.

Create cuts or holes through several parts at once, ensuring alignment of holes.

Find where parts overlap early in the design process so issues can be addressed prior to manufacturing. Highlight overlapping volumes and wireframe all parts that don't overlap for fast analysis.

Once constrained, drag components around in the assembly to see how they will move in the real world. Test mechanism movements, range of motion, and more.

A nested design structure brings order and repeatability to the design process. Create smaller building blocks and combine them together into a finished product.

Control dimensions and other parameters across multiple parts from a single, global design file. Cascade changes instantly across many parts as the design updates.
