https://community.graphisoft.com/t5/Modeling/PROBLEM-WITH-WALLS/m-p/219208#M118928 thank you for your advice, yes i have different height level. Our teacher at school told us to do the exterior walls lower and on top of that we should use arming with concrete and ceiling in your country it is called wreath. so those walls that are in interior are higher than those exterior walls. <span class="lia-unicode-emoji" title=":confused_face:">😕</span> Sun, 01 Nov 2020 15:48:36 GMT Anonymous 2020-11-01T15:48:36Z https://community.graphisoft.com/t5/Modeling/PROBLEM-WITH-WALLS/m-p/219206#M118926 <DIV class="actalk-migrated-content"><R>Hello everyone, <BR /> i have a problem with my walls in my model.

Or it is possible you have many walls from different levels at the same place into your BIM model.
