Can one create a user defined grid system in STAAD.Pro?
Yes, a user defined grid system can be created. You need to go to Geometry menu and select Grids -> Beam Grid. Snap Node/Beam window will appear:
Click on the Create button and this window will appear:
You will need to provide a Grid name, select Grid type (Linear, Radial or Irregular) and set various other options. Once this is done, click OK and created Grid name will appear in the list. Check the box near it to activate that Grid.
As new grids are added or modified, the information is stored in the STAAD.Pro data folder with a GRD extension that allows other STAAD files to re-use these defined grids.
You can also import Grids from the DXF file or Grids previously defined in another STAAD.Pro model by clicking on the Import button. The latter import option opens a browse dialog box to identify a GRD file created by the Snap Node Grid tool. Note that GRD files are only created by STAAD.Pro 2007 (or later).
More information can be found in the STAAD.Pro Help (go to Help -> Contents) chapter AD.2007-1001.1.2 Enhanced Grid Tool.
