Interpolated sections

Hello,
I have a project in which I use Teddy to link Sofistik with Excel. I read structural points and lines from Excel with Teddy, but I have a problem with meshing. I can’t automatically generate interpolated sections like the export option in Sofiplus. What is the solution?
Thank you in advance.

Maybe you need to run interpolation of Cross Sections.
