Creating Basic Parts In Onshape

Entering the 3rd Dimension

Once you’ve gotten a good grasp of sketching, we can exit out of the sketch environment and move onto creating 3D objects in the features environment. Onshape allows for two main types of modeling, solid-body, and surface. The method covered in this document is solid-body modeling, which is needed to create most shapes.

It’s important to remember that the approach to 3D modeling, like sketching, varies between person to person. There is no “correct way” to model, but there are more efficient ways that eliminate the number of operations, decreasing clutter and making your model easier to edit.


By default Onshape provides 3 basic reference planes: the top, front, and right. These planes help define the 3D environment, but you aren’t limited to only them. Onshape also allows you to create your own reference planes from the 3 basic planes or from faces of existing parts.

The Path and The Profile

Many solid-body modelling features will require both a path and a profile. The profile is the sketch or flat surface that you will be extruding. The path is a line or axis that guides the profile’s extrusion.

Profile and Path Before In this image, the profile is the square and the path is the line drawn in a circular path.

Profile and Path After After the revolve function is used, the resulting part looks like this.
