Excel VBA to Generate Joint Coordinates and Member Incidences for STAAD Text Editor using Building Dimensions As User Input

Hi,

Is there anyone who knows how to develop an Excel Spreadsheet that asks for building dimensions (geometry); and translate these dimensions into joint coordinates, and possibly member incidences to copy them over to STAAD Editor. The number of joints (and members) should be able to change depending on the size of the building. (Although, I'm starting on the idea of a simple building, i.e. repeated over a number of bays)

Also, I'm hoping in the future to be able to draw this into a CAD software (using the same joint coordinate system).

Does anyone have experience in this area?

Please help.

Thank you
