Part Design

Onshape delivers collaborative parametric modeling methods for solid, surface, frame, and sheet metal part designs.

What is a parametric design?

Parametric design is a process that enables the expression of parameters and rule-defining relationships among design elements. It's widely used in engineering and design, allowing for the rapid generation and modification of complex geometries and structures. This design method hinges on the principle that changing a parameter updates the design automatically, thereby enhancing efficiency and versatility in the design process. This is taken a step further with the Onshape “Part Studio” approach, where part relationships can be made in a cohesive and flexible manner.

Part Studio Benefits

Onshape's Part Studios environment enhances parametric design, enabling the creation and editing of parts, surfaces, and sketches. It simplifies early design stages by using a single parametric history for reliable part relationships, facilitating top-down design. Parts from Part Studios integrate seamlessly into assemblies, BOMs, Release Management, and more.

Parts may be exported to standard formats like Parasolid, ACIS, STEP, STEP AP242, IGES, SOLIDWORKS, Collada, Rhino, JT, PVZ, and GLTF. In addition, OBJ and STL formats are available, but not recommended if further design work is required.

Yes, you can import non-CAD files like PDFs and images. Onshape handles them the same way as it does with imported CAD files. When you import from the Documents page, the imported file is placed in a new Document. When you import from within a Document, the imported file is placed in a tab within the Document.

Data from most systems import via a universal format like ACIS, JT, STEP, IGES, Parasolid, OBJ, or STL. For AutoCAD solids, the best import format is ACIS, and all 2D data is imported to DWG or DXF. If importing a single design from SOLDIWORKS, it is recommended to save the part as a Parasolid (.x_t). If you're importing a SOLIDWORKS assembly, use the Pack & Go tool.

Yes! Often times, users may need to use mathematical operations to generate curves. Onshape can generate equation-driven curves using a publicly available custom feature.

Yes, you can! Most any CAD system can export sketches to DWG or DXF files. These can then be imported into Onshape to reuse legacy sketch data.

Yes. The mouse settings for Rotate, Constrained Rotate, Pan, and Zoom can be set to mimic those found in SOLIDWORKS, NX 10, Creo, and AutoCAD. Learn more here.
