From the frame to the fixing
A focused workspace for engineers, detailers and fabrication teams. Work with members, connections and drawing views in the context of the whole model.
Place beams, columns and braces using steel profiles. Work with grids, snapping and member properties to develop the frame.
Work with baseplates, end plates, fin plates, bolts and welds. Inspect how the parts sit together in three dimensions.
Create general arrangement and assembly drawings, with dimensions, marks and schedules for review.
Work across your devices
Save your work as Staxis project files in a location you choose. Put a project in iCloud Drive when you want to continue on your Mac or iPad. Close it on one device before editing it on another: simultaneous multi-user editing is not included. Trade Insight does not receive your project through this workflow.
