Question:
I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
Answer:
In the SHAPE‑THIN stand-alone program, it is not possible to calculate the c/t-field for rounded elements entered in the cross-section. If you replace all arc parts in this cross-section, calculate the cross-section, save it, and import it into RFEM again, the design will be possible.
