I would send this into support as you getting problems with this file one they might be able to spot the problem and it might just by tied to a bug in x18

If I delete the curve part of the roof the problems goes away, as a fix could the curved portion be done with a molding polyline you would be missing ridge capping so may not be suitable, hopefully others will have a better solution

See if that is this heading in the right direction its still a bit rough and need some fixing but no point if its not what you want. You had a heap of floor platform holes that was giving chief trouble that needed to be deleted and few other little problems 515040722_silobarnhouse mark edit.plan

You could try exterior room molding polyline

Have you looked at the new feature in x18

When you install x18 it will ask you do you want to import your user libarys toolbars setting just select the things to import

That was it i just never had the roof pulled to the roof to pulled to the other side of the wall thanks

Shane I see you got that model working better than me how did you get roof cuts wall below to work i tried and made the wall disappear, what is your secret ?

See if this is any good in the attached file 1057885320_36_deanwood_circle-MOSTCURRENT_auto_save_bak.plan

Something else i put together electrical symbols Electrical Au.calibz

Bonus librarys

I would auto build the orignal end section while turning of roof in newer middle section then manual build roof planes in the newer section job done.

Have a look at this file a bit of guess work auto roofs are turned on those front gables need to be manual I think after you turn of auto roofs 1884941697_Untitled2 Mark edit.plan
