Prismatic Member Design

Hi Team,

I have some bracings which I have defined as a Rectangular Section (Steel S275) of size 35x4 mm. In the output, I could not get the design of those members. The Warning is like "MEMBER   104-DESIGN NOT PERFORMED WITH PRISMATIC PROPERTIES".

I tried replacing these into Dutch Plate Sections (35x4 mm). In this case, the design was being done in SS6 software but not in Connect Edition (Especially for Torsion checks using EURO Code).

I really like to use STAAD PRO but I do not like to analyze in staad and design manually for bigger projects.

Is there any way to get it done Through Connect Edition? SS6 Edition is very slow, hence i do not prefer that for bigger models.

Awaiting for a valuable response.
