How i fixed i just selected the gable attic walls then just auto re built them and the side triangle walls i had to pullback the lower roof plains as chief stops walls below roof plains

See if that is getting better i think may have setup your exterior walls wrong unless i am missing some thing to me they should be a single wall unit Also that small image is a bit to small to see Barndominium.zip

No problems for me amd desktop and laptop both good

upload your file you will most likely get a fix

open this plan i have put some instructions in it to follow Sloping Block 2.plan

Here is chief file with cad in it to help with showing house position Sloping Block.plan

the hatched box is a copy of your terrain is that how you would place your house or if not can you explain

Are you using x7 or have forgot to update your signature in chief talk

Ceiling height needs match

Would that be close enough if so it is just using railing panel from core catalog and the hand rail can be set to what ever you want

try this file i put the roof at 25 pitch Huis_mei_2021.plan

Have look at this file see if it is on the right track Huis_mei_2021.plan

Have a look at this file it is working a lot better i added a terrain break set retaining walls to default top and bottom heights and tweeked the terrain data to help 24wc_left_7ft_exp2.plan

When i was looking at your file i noticed you had terrain data on top of terrain data there is a elevation region in front of garage if you keep the elevation region and remove the elevation lines in the same space as your elevation region buy doing a complete break and deleting the over lapping data your terrain will behave much better you should never have multiple elevation data in the same space
