Key Benefits for Structural Engineers

Easy to use menu

Model & Loading

Build your models with confidence.

  • Sketch, Import, Generate, or Copy & Paste
  • Work with beams, columns, areas instead of low level FEA
  • Easily create and edit frames, trusses, tanks, towers, or whatever!

Apply loads to meet your code requirements.

  • Point & click loading to one or many objects
  • Simple and flexible load cases
  • Optional, custimizable, and automatic building-code load combinations

Sktech models graphicallyAnalysis & Results

Get fast, and powerful FEA results.

  • 64-bit, muli-threaded, sparse matrix, validated solver
  • Static, Dynamic, P-Delta, Direct Analysis, Time-History, and more.
  • Automatic statics-checks and basic validations prevent careless mistakes

Understand your structure's behavior.

  • Graphical display of displacements, forces, stresses, and reactions
  • Detailed member and plate graphs
  • Double-click for detailed textual reports

Visualize deflections and forcesDesign & Report

Checks for steel, wood, concrete, cold-formed, and aluminum.

  • Member for checks with AISC, NDS, ACI, NAS/AISI, and ADM, and more.
  • You control bracing, size constraints, and other design parameters
  • Fast unity-checks, with optional member-size or detail optimizations
  • Concise reports with checks, intermediate values, and code-references

Create reports to document your project.

  • Reporting is a breeze with drag & drop simplicity and WYSIWYG viewing
  • Save your customized reports with projects or as templates for future use
  • Copy and Paste graphics into reports
  • Print reports, or export to Clipboard, or Save to standard file formats

Drill down to the numbers

Three VA Levels Available

Just enough features to get your job done right. Compare the 3 Levels, or view the detailed feature list on this page.

  1. Simple (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.
