Still needs a good bit of work, but this shows what you can do by changing ceiling heights. I also added a wall for the highest gable.

Well done first post. I'd draw the bay in manually. The Bay Window tool is quick, but has many limitations. You will get a foundation under it, so at some point, you will need to turn off auto rebuild foundation and delete the unwanted walls. For the roof, remember ceiling heights control how the roof builds, so you will need to temporarily adjust them until the roof looks good, then turn off auto rebuild roofs., and set the ceiling heights back. The gables over the garage will be a challenge, I believe. Here is the results of a few adjustments.

Did you try replacing the wall as David suggested? Double click (or whatever you do on a Mac) on the section you want to change. Go to Wall Types, pick a unique one and see if it changes.

I imagine that (attic) wall is auto generated by the program. You need to replace it with the correct type -- whatever you used for the exterior wall type.

I'd raise the porch roof up as high as possible and then let the connections on either end fall where they may. I would then suggest the same thing, but cutting the main roof overhang off and connecting a new roof there. I guessed you were in Canada somewhere close to your actual location. Looks like I could walk from the airport , then on to the coast. It feels like Canada here. About 10" of snow on the ground and lows around 5 degrees F (-15 C) predicted over the next few days.

Can you open the item itself? Select it and Control-E. If so, there should be options there. I imagine there are other items on that layer that you do not want to change, so you probably don't want to make a change at the layer level.

When you select them, the layer they are on is displayed in the status bar. They may be on a generic layer with other things you don't want to turn off, so you could try changing the text to be white and very small, for example.

It's neat that there is a family connection with the house. I was wanting to see pictures of the real thing. Here is another idea. I tried not to change much, just rearrange a bit. My thinking on the outside was to maintain an as built look, so looking at the house, the addition looks like part of the original house, and not an add on. Looks like you will have a bit of exposed foundation, and if you wanted to use some rock, that would be the place. If you use the upstairs as bedrooms, I'd encourage you to consider opening them up a bit. Don't know about your location, but here, I'd need to bring them up to code standards for access and egress. It will be less expensive in the long run to do the work along with the addition, rather than wait.

Thanks Bruce. Looks good. Manual roofs take practice. You should be able to auto build this roof too -- just a matter of getting all the settings correct. I'm not generally a fan of dormers, but I think 2 would add something to your front elevation, and give those "bedrooms" on the 2nd floor some more light and space. I'd stay away from sticking rock randomly on the house -- because that's what it will look like. Also consider trying to minimize the garage, maybe painting the door a bit lighter or darker than the siding. The focus should be on the entrance. I'm guessing your addition is the hip roofed space on the left? It really needs a gable roof to match the older part of the house.

What do you want it to look like?

You might send this issue along with your plan file to tech support.

Right click on a roof plane. You will see Display on Floor Above (also Display on Floor Below) down near the bottom of the menu.

Open the cabinet spec dialog. Go to Front. Delete toe kick. Add back a filler if needed.

Is there a 2nd floor living space?

I suggested a soffit because of the way they display in plan view. Soffit on left.

You might post the plan file.

This has been requested but Chief does not seem interested. None of their products will do this. Ideal project for SketchUp.
