A screen shot to help

Cross section camera I drew a cad triangle the shape of the roof got the length of the short side and subtracted it from the default ceiling height

Check out the edit area tools in the edit menu

I figured out how to share with out email https://drive.google.com/file/d/1-GZqTjLXFhuF6xUMjPHeoKWezez-_L5_/view?usp=drivesdk

Spent a bit more time on your terrain if you still need it let me know maybe private message so in can share the file on google drive as its now 24 meg zipped

Watch a training video on manual roofs then you will not be at the mercy of missing information

On the small gable roof plains you have the base lines on the inside edge of the main layer to me they should be on the outside edge of the walls main layer i the reconnected the roof edges and the stray siding went away See if that is any good 1866557940_RoofwallissueMark Edit.plan

I have it working but file is to big so I put it on google drive https://drive.google.com/file/d/1CoYTpBBTNXRXu6XqFcW3jNzTxGWrYBZN/view?usp=drivesdk It was building walls set to retaining walls elevation data crossing retaining wall

You have uploaded a file that is open so it has no data , save the file close chief and upload again.

See if that is any better i got rid of gable line as it was stopping roof on soak tub room and used Make roof base polyline and tweek it at the problem wall intersection, so now auto roofs will only build to roof base polylines so if you change your model you will need to change roof base polylines BASSETT 2 - PROPOSED.zip

See if that is correct i just added a gable line so auto roof are good others may have a better way BASSETT 2 - PROPOSED.zip

one more

Not substance i did it with a program called genetica as substance could not fix the bad lighting, Genetica has slider to try and equalize the lighting

See if that is good enough

The image you have found is not any good bad lighting and has no grout it will not work you need a image with even lighting and has half grout joint around it edges.

Try and zip or compress the plan or put it on dropbox, google drive or one drive and send them a link, another option is add the material to library from plan materials then export it to your desktop upload it to the forum or send to chief support

Video showing how i fixed error also attached file as in video 2024-03-05 0428.zip

Have a look at that file if it is any good i try and do a video explaining what i did 2024-03-05 0428 Mark Fix.zip

there is only one its shown in my screen shot one elevation region go to the wrong side of the retaining wall

Thanks for the info not sure what is going on on my end with file size jump

I tried your suggestion increasing terrain size that made 7 seconds quicker, did you get a massive file size increase ?
