If you want to place your own CAD block to the Catalog, fill in the data (sections 1./2./3.) and submit it with the 'OK' button. To upload blocks you have to be. There's a section on LISP development. You could use the AutoCAD LISP. Advance Steel Shapes insertion by AutoLISP.

Hi, I understand that you would want to know how to create a beam with a specific section using LISP commands. Best And Fairest Software Informer on this page. First of all I would want to reinforce the recommendations from previous comments: - I would highly recommend you to use AS API (COM or.NET) and / or Dynamo for your applications. My opinion is that it is way more beneficial to spend your time and energy using the current supported developing tools, than walking on a path that it not supported from several versions. You could use the AutoCAD LISP, but you will be able to call only the current implemented AS commands.

There are not many parameters that are available directly, to be used in the command line or in AutoCAD LISP. For example, you cannot indicate a specific section to be used when create a beam. The Advance Steel Visual Lisp is not supported anymore, as far as I am aware.

So it is not helpful in your case. If you want more than just create a beam, we get back to AS API or Dynamo. Best regards, Emy.
