What's the best way to model curve roof

Hi, Everyone. I was modeling curve roofs using mesh method as shown in below picture, but there were some issues such as mesh node control, inside shape control and structure. So I'm seeking help to find the better solution. Thanks

Try shell tool if roof is not convenient.

Shell tool is the answer.

i'm not sure if this is what you want to achieve.

as others have said, the revolved shell is the best bet. You can use the same composite as your main roof body. You may need to place some dedicated operators (use simple planar morphs for this) and trim with solid element operations to get them to join cleanly to the main roof body.

the shell tool should give cleaner curves, rather than the more segmented appearance of the "curved" roof solution... even though a framed roof would be segmented when built, most wouldn't want to see those lines.

white material is using shell tool. yes you can remove the lines, if removing lines is just the issue when you render the model the lines would not be shown.

it really depends on how you want to show your drawings like the 2d representation of the model in plans etc. like @4dProof said the plans might be used for construction therefore contractor might need how the roof is being segmented.

There are lots of ways to do this but in end what do you want to achieve?

Hi, thank you very much. I am not skilled on shell tools, I will try
