Three Levels Available

Just enough features to get your job done right. The free-trial is the 'Advanced level'. If you buy a lower-level you may upgrade to a higher level for the difference in price. Compare the 3 Levels. Compare with other IES Products.

  1. Analysis-only in 2D and 3D (no Design View window)
  2. *with Design: adds code checks, member sizing
  3. **Advanced with Design: adds meshed-areas, nonlinear, time-history, and more.

Design Checks & Building Codes*

  • Smart and flexible setup: bracing, deflection checks, size constraints
  • Updated! Steel AISC 360-10 or CSA S16-14 Design for frame and truss members *
  • Updated! Concrete ACI 318-11 Design of Beams, Columns, Flat Slabs (ACI)*
