Product design collaboration is important for your product. That means it’s important for your customers. And it’s important for your design teams, too. So, why not make it user-centric, and simple?

Let Designers work together from anywhere, anytime on any size assembly. Make design collaboration easy for your teams, invite key stakeholders into the discussion, and see the positive effects ripple across your product lifecycle.

SOLIDWORKS 2021 brings a slew of improvements, new features and tools that are all driven by user experience – with collaboration in mind.

So, let’s take a look at some of the most exciting updates available with SOLIDWORKS 2021.

Detailing Mode

Detailing Mode enables users to open drawings containing large assemblies, lots of sheets, many configurations or resource intensive views in seconds. Enhancements to this mode include:

  • Improved drawing creation performance
  • Improvements to adding hole callouts, editing existing dimensions and annotations, and adding detail, break, and crop views


SOLIDWORKS Assemblies consist of many components, either parts or other assemblies, called subassemblies. This core tool has several key functionality improvements in SOLIDWORKS 2021.

  • Export interference detection reports with images to Microsoft Excel
  • Use Change mate alignments on edit to warn you when mate changes result in errors that can be avoided by flipping the alignment of the edited mate
  • Automatically resolve lightweight components on expanding the Feature Manager node.
  • Save defeatured models as configurations, change between full and simplified versions, and mimic other configurations
  • Benefit from improvements for design tables, exploded views, mates, and mirror and pattern features
  • Open, save, and close assemblies with significant performance improvements
  • Use curve length in chain patterns along paths, not chord length
  • Detect and report circular references

Model Display

  • Work with improved performance of occlusion culling, silhouette edges and drawings, and quick configuration switches

User Interface

  • Pick colours for appearances from external applications
  • Search for tools on Shortcut Bars and Commands tabs in the Customize dialog box
  • Display translated feature names in the Feature Manager design tree

Parts and Features

  • Use Redo for more than 60 features and tools in parts
  • Add edge flanges on nonplanar tangent edges in sheet metal parts and flatten complex flanges
  • Add and evaluate equations in file properties and cut list properties
  • Transfer part-level materials when you insert or mirror a part, derived component part, or mirrored component part
