  • DXF points imported as vertices
  • Overlapping boundary subgrade handling (max, min, average, or sum)
Legacy support was removed. To open VisualFoundation 6.0 or prior projects, use VF 7.0 to upgrade the project-file, then it will open in VF version 8.0 or newer. If needed, contact support to obtain a download link for VF version 7.0.

This version represents a complete "rewrite" behind the scenes, using new technologies for graphics, reporting, UI, and more. There are many fundamental changes from version 6.0, though it read the older file format and the fundamental features are very similar to prior versions. We've upgraded and changed where it made sense for consistency with other IES tools, for ease of operations, for performance, and for greater engineering control.

One of the biggest changes is fully-automated background analysis. Without slowing down you or your system, we take advantage of the fact that 90% or more of your CPU processing power is going to waste. After every change, VisualAnalysis will start working on analysis results and/or design checks. When you are ready to see them, just switch to the Analysis Results or Design view and they will likely already be available. If not, just wait a few seconds and they will appear, you can view progress in the status bar, if you wish, by using a preference setting.
