How do I create symmetry in a SOLIDWORKS assembly?

With this SOLIDWORKS tutorial, discover how to create symmetry in an assembly: follow our expert's technique!

Initial situation

We have constrained the left-hand side of this assembly on SOLIDWORKS and would like to save time by doing the same on the other side.

Objective

Create foot symmetry in the assembly:

Steps to follow

Tip : Make sure you create parts with centered planes to avoid adding extra planes.

  • After assembling the left part, go to the Assemble -> Linear Repeat Components -> Symmetrical Components tab.

  • Select the plane of symmetry, then the component(s) to be symmetrized. In our case, the plane of symmetry is the front plane.

  • To access other position options, click on the blue arrow :

  • Selecting the orientation of parts to be copied symmetrically :

To create a new symmetrical part, use this icon :

In our case, the simple copy of the part and the 1st orientation is the right one:
