HELLO; I ADDED 1 FLOOR IN AN EXISTING PROJECT. (I LOCKED ALL OF THE REINFORCEMENTS BEFORE ADDITIONAL, THEN I COPYED A FLOOR AND I LEFT THE REINFORCEMENTS ON THE FLOOR I JUST ADDED) WHEN I MADE A 10% CG PERFORMANCE ANALYSIS, SOME CURTAINS WERE CRISPY CURTAINS. HOWEVER, WHEN I LOOKED AT THE CURTAINS, THERE WAS NO SITUATION OF ANY INSUFFICIENCY IN THE REINFORCEMENTS. FIRST, IS IT NORMAL FOR THE REINFORCEMENTS TO BE TROUBLE-FREE ON CURTAINS THAT ARE BRILLIANT IN PERFORMANCE? HOW CAN I FIX THIS SITUATION? SHOULD I DO STRENGTHENING?
