Mark 6.1

Release date: 2/27/2022

Build number: 22.01.15


  • Added ability to use geometric tolerances for 1D RSS, 1D worst case, 1D Monte Carlo, 1D/2D/3D worst case, and 1D/2D/3D Monte Carlo tolerance analysis by allowing dimensions to be negative.
  • Added tolerance limits to 1D Monte Carlo and 1D/2D/3D Monte Carlo tolerance analysis to truncate dimensions.
  • Added ability to vary alpha and beta angles within a range in 1D/2D/3D worst case tolerance analysis.
  • Added ability to treat alpha and beta angles as random variables in 1D/2D/3D Monte Carlo tolerance analysis.
  • Changed 1D/2D/3D worst case tolerance analysis to treat each dimension as a uniformly distributed random variable.
  • Added ability to find min/max deltas in 1D/2D/3D worst case tolerance analysis.

Mark 6.2

Release date: 6/13/2022

Build number: 22.06.29


  • Added acceleration to unit conversion tool.
  • Added liters/min to flow rate in unit conversion tool.
  • 1D Monte Carlo & 1D/2D/3D Monte Carlo tools: When using the normal distribution, the mean must lie within the upper and lower limits (if they exist).  This avoids sampling that may not have a feasible value resulting in an infinite loop condition.
  • Bug fix in beam diagrams.  When a point load or support was exactly at the midpoint of an increment, would cause array out of range error.
  • Fixed form formatting issues.

Mark 7

Release date: 7/5/2023

Build number: 23.01.22


  • Added bonus tolerance calculator.
  • Added coolant calculator.
  • Added angular velocity to unit conversion tool.
