Does SolidWorks Use Multi-Threading…..Yes!

Article by Chris Briand, CSWE updated January 31, 2011


One of the most common questions we receive is in regard to how SolidWorks uses processors that support Multi-Threading and if Multi-Threading should be enabled via a computers BIOS or not.

In addition to the well known advantages with Simulation and Rendering, other operations within SolidWorks that can take advantage of Multi-Threading include:

  • File Open
  • File Save
  • File Conversion
  • Boolean
  • Silhouettes
  • Line generation
  • Mass properties
  • Body check
  • User Interface Activities (dialog box interaction, redraw, etc…)
  • The Swbgproc.exe process which silently updates HLR drawing views to High quality from draft.

In prior releases with older P4 class machines it was suggested that Hyper-threading be disabled in the BIOS to streamline performance. With modern “Nahalem” processors (Core i3, i5 & i7) this additional step is not required.
