Create highly structured and detailed assemblies with built-in standard hardware and parts from other Documents. Employ top-down assembly design and assembly motion, along with automatic sizing and insertion of standard fasteners.

Linked Documents

Insert parts, subassemblies, surfaces and sketches from the current Document or from other Documents, linked to a specific version or revision. Linked Documents make it easy to share standard company parts or approved supplier parts to all designers at once. Version and revision updates are flagged everywhere a linked Document is used, giving the designer the option to update to the latest or not.


Capture positional or complex kinematic relationships with a single high-level Mate feature, significantly reducing the time and effort required to build complex assemblies. Add relations between Mates to create gear, screw, rack and pinion, cam and linear motion behavior. Define precise positioning, offsets, motion limits and animations. Pattern parts by incremental distance or by geometric shape recognition.

In-Context Design

Design parts in the context of a higher level assembly and manage updates when necessary. Onshape's unique take on in-context design captures a snapshot of the assembly and enables any part to reference any other in the assembly. This enables parts with motion to reference others as they move ensuring correct fit and clearances. References are never lost or broken so parts always update in a predictable manner.

Standard Content

Insert standard hardware from a built-in library provided by Onshape and available to all users. Add company specific metadata to each fastener for correct Bill of Materials data. Fasteners automatically size based on the selected hole and insert into the correct position. Easily build stacks of fasteners on-the-fly or add to existing stacks which automatically adjust their positions to accommodate new hardware.

"As our company grows, Onshape has made it so much easier for me to manage our different engineering groups and review their progress in real time."

"I haven’t used a file-based CAD system yet that hasn’t crashed on me, especially in the concept-generation stage. I’ve never lost work in Onshape and I never have to remember to hit the save button. At this point, it would be a struggle to return to our old CAD system."
