How to speed up calculations in TBC

Whether it’s General Use or Reporting, we often get asked if there’s a way to speed up calculations in TBC. TBC’s default surface calculation when comparing 2 surfaces is to calculate the difference in between each triangle 12 different ways. This over calculation isn’t necessary in most situations and other software applications certainly don’t do this.

This calculation setting is located in Project Settings / Computations / Surface / Volume Computation. TBC defaults to Track All Triangles. If you change this setting to Do Not Track Breaklines you should see a noticeable difference in speed / performance in calculations. You should also notice a performance difference in running reports.
