M. To generate geometry from a DXF file

This is a utility which allows the geometry (nodes, members, plates, etc.) of a previously created model to be imported and altered.

This feature supports a limited number of CAD entities like Line, 3D-Polyline, and 3D-Face.

If the geometry of a model is created using a drawing program like AutoCAD and saved in a DXF file, it can be imported into STAAD using this utility.

Select Import CAD Models from the Model Type drop-down list.
Either:

Drag-and-drop the Scan DXF icon into the view window.

or
Double-click the Scan DXF icon.

The Open dialog opens.
Select the DXF file you want to use and click Open. The drawing geometry is opened in Structure Wizard.
