I don't think Home Designer or Chief will create the railing using their automated tools. You could with some work, manually create it in Chief. One big advantage of Chief is its various tools you can use to create things from scratch. I just did this curved coffered ceiling in Chief. A bit tedious, but not difficult. You would need a 2nd program like SketchUp to replicate this in Home Designer.

Chief Premier Pro does a good job at roofs. The PolyLine Union tool I referenced above is just a convenience as it saves you from deleting and then extending an existing roof plane.

It's not in Pro. I forget how limited the Home Designer products are. Glad the video was helpful.

That's an auto generated attic wall that spans from the ceiling to the roof. What were you expecting? Raise the deck room ceiling to make it go away.

Not in Home Designer. Google 3D Warehouse for similar symbols.

Go around and use the Join command to join each roof plane edge to the one next to it.

Ceiling Over This Room

Divide the space with a wall. Lower/raise the floor.

Have you considered this? It stays true to the original house, and gives you a few more sq ft in the garage.

Auto roofs may not always work. With Pro, you have manual roof tools. Suggest using them to solve your issue,

You will need to add your own doors to show open like your image above.

Copy/Paste ?

I looks like you have done that on the left side. Have you reviewed your dimension defaults and docs on dimensioning? Like a Point?

Have you watched the roof webinars on the Chief YouTube channel.

Looks like you used a small roof plane over the bumpout. Select the main roof plane, put a break (3 key) where the arrow is and drag the lower edge out.
