Hello, im new in using Teddy, now iam planning to model a continuous beam with varying cross-section by using sofimshc and sofiload.
My ideal is similar to what we can do in Sofiplus,
First, I create the Axis and its geometry by using GAX and GAXC
Then, I choose the station in the axis and create the line GAXP and attach it to my cross-section.
I think the problem is that the station can not have two cross sections at the same position, so I tried to make tiny gaps between them, which caused discontinuity and instability. How can I fix that. Thank you.

Hello, I’m also thinking about the structure line to connect 2 nodes, but it seems like that structure line SLN doesn’t support 2 cross-sections like Sofiplus. Thank you for your help.
According to the syntax, I found a command using the structure line. However, my structural line is divided into elements, each of which starts with cross-sections 101 and 102. What I want is a structure line with a start point and an end point, then the mesh will be divided into elements. Thank you for your help. Syntax: Beams with linearly varying sections can be defined by entering two section numbers separated by a dot at NCS (i.e. ’1.2’ ).
