Routing Routing is available in SOLIDWORKS® Premium and SOLIDWORKS Ultimate. Contents Redesigned Routing Tooltips (2025 SP2) The tooltips in the SOLIDWORKS Routing interface are redesigned to improve clarity and usability. When you hover over a wire, cable, or harness, the updated tooltips display key details in a logical order. Support for Clip Assemblies and Clip Parts in the Routing Component Wizard (2025 SP2) The Routing Component Wizard supports both clip assemblies and clip parts, allowing you to define and configure assemblies as routing components. The basic requirements for both types are the same and the steps to create them in the Routing Library Manager follow the same process. Improving Performance in Flattened Harness Assembly Edits (2025 SP1) The editing tools in the Edit Flattened Route PropertyManager perform faster, enhancing your experience for editing flattened harness configurations. Create a Flattened Drawing with Cleaner Output The following updates in flattened drawings provide cleaner output and improved workflow: Customizing Slack Percentages in the Route Properties and Route Segment PropertyManagers In the Route Properties and the Route Segment Properties PropertyManagers, you can define a custom value for the Slack Percentage for individual route segments. This value overrides the slack percentage specified in Tools > Options > System Options > Routing . Enhancing Pipe and Tube Modifications When you edit a route assembly containing pipes and tubes, the SOLIDWORKS Routing software modifies existing components instead of creating new virtual components.
