Good work"YasinTezel":1342jtoy" said:Hi The screen you defined does not meet the 1/6 screen aspect ratio condition, therefore the headline region has not been created. The screen you defined looks like 25x146. When you make 25x150cm and the TBDY 7.5.2.1. conditions are met, the headline region is created. Independent of the regulations If you want to interfere with the header areas. The header area dimensions can be edited in the Rebar tab of the curtain settings. If you change the size, remove the Rebar locks before analysis.
