MODELING IN AUTOCAD & IMPORTING TO STAAD PRO
This method is useful for AutoCAD Professional to prepare 2D or 3D Geometry in AutoCAD into STAAD Model.
The following steps will help to import DXF files into STAAD.Pro. Always make a backup copy of your DXF file before proceeding with the following steps.
For Stage 1:
1. Remove all the text, dimension lines, and unwanted views. 2. Need to draw a stick line diagram using simple
elements in the CAD package. If you are drawing a stick model on top of an existing model make sure to use a different layer on top of the existing view in the dxf file. For example, you will need to draw a line representing the centerline of the HSS section. 3. Remove the original elevation not the newly created centerline diagram. Use the Layer on/off feature to delete the elements under the unwanted layer. 4. As a result of steps 1-3, you will be left with a simple stick model of the structure 5. Scale the model to match the import unit system (may or may not be necessary) 6. Save the file as a dxf file and close it. Close the CAD package. 7. Open STAAD.Pro and create a new project. 8. Click on
command menu and select the
option in the
dialog box. 9. Click on the
button. 10. Select the dxf file and click on the
button. 11. The DXF Import dialog box will appear. The axis system in your CAD package will be different from the axis system used in the STAAD.Pro model. The Y-Axis usually is the axis of gravity in STAAD.Pro the Z-Axis is usually the axis of gravity in the CAD products. Hence you need to specify which axis is the axis of gravity in your STAAD.Pro model. If the axis system is the same in the STAAD.Pro model and the dxf file, then select the
option. If the Y- Axis is the axis of gravity in the STAAD.Pro model and Z-Axis is the axis of gravity for the CAD model, select the
