- Automatically Optimize Resolved Mode
You can optimize resolved mode automatically. Using this system option improves performance by selectively using lightweight technology when you load components in resolved mode.
- Repairing a Missing Mate Reference
You can repair missing mate references for references to faces, edges, planes, axes, and points.
- Delete Missing Components from a Model (2023 SP1)
You can delete all missing components from a model in the Find References dialog box.
- Additional End Conditions for Cut Features
More end conditions are available for cut features in assemblies.
- Previewing a Replacement Component
You can preview a replacement component in the Replace PropertyManager. You can specify the scope of the replacement.
- Specifying a Color for an Explode Line
You can use a system option to specify an explode color. You can change the color of explode lines in an exploded view.
- Selecting a Configuration for Skipped Instances
You can select This Configuration 
, All Configurations

- Specifying a Default BOM Part Number
In a model, you can select Document Name or Configuration Name as the default Bill of Materials (BOM) part number for new configurations.
- Magnetic Mates
You can suppress magnetic mates and connection points.
- Overriding Calculated Values in a Design Table
When you close a design table that contains manually entered values for $SW-MASS and $SW-COG, SOLIDWORKS prompts you to use either the manually entered values or the values calculated from the model geometry.
- Assembly Visualization
In lightweight mode, SOLIDWORKS calculates more Assembly Visualization columns without setting the lightweight components to resolved.
- Configuration Publisher: Updating a Multiple-Configuration Model
For models that have multiple configurations created with a custom PropertyManager, the PropertyManager icon changes to 
after you manually add, delete, or rename a configuration. Update appears when you right-click PropertyManager.
- Fix and Float Options When Inserting a Component (2023 SP2)
In the Insert Component PropertyManager, you can specify the position of a component as Only fix first component, Fix, or Float.
- Selecting Flexible Subassemblies and Components (2023 SP2)
