Beam intersection using OpenStaad

Mishal Mohanlal — Fri, 05 May 2023 08:07:55 GMT

Hi Guys

I am currently trying to use the IntersectBeams function to intersect a group of beams. The function however continually fails.

Refer to the code below.

Noting that if I use the modelling interface I am able to intersect the beams.

    nbr = []
    print(geometry.IntersectBeams(2,[100,101,102,103,104],0.1,nbr))
    print(nbr)

Inconsistent units

Hi Guys

I am a new to Staad and only really using it through the API interface at the moment.

I have applied a few point loads to a structure however the units are in kNm.

What is the cause of this issue?

Error when opening a new file using OpenStaad and python

Mishal Mohanlal — Wed, 03 May 2023 12:45:38 GMT

Hi Guys

Using the NewSTAADFile function I am able to provide a location and file name for a new .STD file.

For my current case I need to read a file name from excel and then add it to the path so that I have a file location and name to use with the NewSTAADFile function.

This however does not work.

Please refer to my code and the associated error below.

I am using the Pathlib package to develop the path

Can someone please assist?

Loc = r"C:\Users\mishal.mohanlal\Aurecon Group\GDC ERM - General\1 - Projects\000000 - NE REZ substation automation\Python automation\Staad Pro models\\"
Fname = "MM" + ".STD"
File_Path = pathlib.PurePath(Loc,Fname)
print(File_Path)
os.NewSTAADFile(File_Path,4,5)

***ERROR BELOW***

File "c:\Users\mishal.mohanlal\Aurecon Group\GDC ERM - General\1 - Projects\000000 - NE REZ substation automation\Python automation\Substation (R2).py", line 44, in <module>

Python not finding StaadPro.OpenSTAAD

Mishal Mohanlal — Tue, 02 May 2023 09:24:40 GMT

Hi Guys

OpenSTAAD was running last week and now for some reason I am having an issue with the "os = win32com.client.GetActiveObject("StaadPro.OpenSTAAD")" command.

I get the error presented below. For some reason I think that STAAD cannot be found any longer.

Has anyone has a similar issue previously? Or knows how I ca resolve this issue?

os = win32com.client.GetActiveObject("StaadPro.OpenSTAAD")
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "C:\Users\mishal.mohanlal\AppData\Local\Programs\Python\Python311\Lib\site-packages\win32com\client\__init__.py", line 93, in GetActiveObject
