The SOLIDWORKS Symmetry check utility allows you to evaluate a part or assembly for symmetry. It can also be used to split a part into the smallest repeatable symmetrical body, which is useful when running a simulation analysis.
Manual face check evaluates the current configuration of the part for symmetry. If you are working with a weldment or other multi-body part, you will need to select the body to evaluate, as the check will only evaluate a single body.
Once you have selected a body (if applicable), define the plane used for symmetry and run the check. The symmetry plane can be defined by the following:
Once complete, the analysis will group all faces by Unique, Symmetric, or Asymmetric and further categorizes them into subgroups.
The Unique faces are grouped based on which side of the symmetry plane it lies.
Colors are applied to all faces according to their group. These colors can be modified under color settings before or after the check has been run.
If you would like to run a different check, select recheck to clear your selections and start the process over.
This option is not available in multi-body parts. If there is symmetry, the model will show the different splits available, allowing you to divide the part into a smaller symmetric portion. If there is no symmetry, you will receive a message alerting you that no symmetry was found. The part shown below can either be split in half or quartered.
Choose the body to keep and select split part. A split feature will be added to the feature tree as well as the plane(s) needed to split the part.
Define the plane used for symmetry, determine if you want subassemblies to be treated as single components and run the check.
Once the check has been run, the components are categorized as either Symmetric or Asymmetric, and colors are applied according to the color settings.
The assembly below is a combination of weldments and single body parts therefore, the frame's components are not evaluated and show as asymmetric.
