Hello,
I am using your spreadsheet utility version 6.2. When I try to set the materials for a Uniaxial Stiffened Panel, using *GroupMaterial, if I only set a Top Face material, i.e. code 1, this works correctly, however, if I then set a Web material, code 2, the Top Face material is removed and all materials are added to the Web material.
Top face and core material are set correctly for Unstiffened Plate/Sandwich Panel Family.
Regards,
Ruben
