For files created with SolidWorks version 2013 or earlier, you can use configurable equations unless:
- The model has design tables.
- One or more equations are suppressed in one of the configurations.
- The model has two or more equations with the same name, for example D2@Sketch1.
To use configurable equations with one of these existing files:
- Remove conflicts by performing the following actions:
- Delete design tables.
- Remove suppressed equations.
- Ensure that each equation has a unique name.
- Save the file with SolidWorks version 2014 or later, and re-open the file.
