Modelling principles
Following terminology is used in the software:
- Profile - pre-defined shape of cross-section from default database (e.g. hot-rolled steel profile). The geometry cannot be modified.
- Shape - general closed polygon with assigned material
- Opening - general closed polygon without assigned material, any opening has to be inside of one shape or profile. No overlapping is permitted.
Modelling principles
Following rules have to be respected when modelling a cross-section:
- The number of particular objects is not limited
- The objects (profiles, shapes, openings) cannot intersect or overlap each other
- Any contact of two objects should be done from outer edge, the contact from inner edge may cause incorrect results.
- The profile material has to respect the database sorting (e.g. for profile IPE200, it is possible to select only steel grades, not concrete strength classes). This limitation is valid only for profiles, it is possible to convert profile into shape and change the material.
- It is not necessary to insert opening in cases, where one shape or profile is inserted into another one (e.g. steel I-profile in concrete column).
