There are trapezoids in the axles due to the land, as far as I understand, idecad does not like the trapezoids very much, on top of that, we couldn't get out of the problem when a reverse beam was made. The beams on the 1 axis will be reverse beams, but the program keeps giving errors. "Exceeded maximum margin, there are objects with insufficient cross-section or not conforming to the rules" and it gives B problems on columns. We tried everything possible, changed the column sizes, changed the orientation. It's okay when we make a straight beam, but we have to make a reverse beam. We are using the 5.511 version of İdecad, the project is being solved in the demo of the latest version, is there a problem with the version? Good work.
