Here is an example of a simple building with one of the interior walls being set to be load-bearing. Pictured below, is the resulting automatic foundation generated. I think this is why CA is creating walls and footings below some of your interior walls. It may be also that those areas in your screen clip have a different floor level that is lower than the surrounding floor.

The end gable is correct and should remain. See my previous post on this build.

Hi In the file that you posted there were a couple of things that I noticed in the file before I did anything other than open it. 1) The roofs were in manual. CA would not generate any changes to the roof structure. 2) The wall assembly that has exposed framing has stucco on one side and drywall on the other. So I dug into the geometry of the roof and wall as shown in your screen shot Notice that the longer roof does not cover the wall below (that is an attic wall.) Also notice that the shorter roof cuts halfway into the attic roof. So by pulling back the shorter roof to just touch the attic wall the outer stucco layer shows and the framing is hidden. Also pulling out the longer roof, an adequate roof overhang is achieved. Hopefully this helps.

Very similar to Steve's solution. I did this before I noticed that Steve had fixed it. I copied down all the roof pitches, turned on autorebuild roofs, then worked my way around the building adjusting pitches, gable and hip roof settings. I had to fix some ceiling heights and then created the gable for the entrance using a gable wall line. Disabled auto roof build and then adjusted the gable. Kinzler Roof Problem.zip

Doll house views work that way, as do the model slicer tools.

If you post the plan file one of us will more than likely post a fix for the problem.

Would you have a gable at the exterior wall edge? If so you can use a gable line over the entrance wall area, assuming that you have auto rebuild roof enabled.

For sure you should contact tech support to report this.

Although I haven't tried this, you might put a soffit under the stairs and put the light there. Or, you might create a ceiling plane under the underside of the stairs and put the light there,

I exploded the dormer. Then manually adjusted the roof following the suggestions that Eric made. I duplicated this in X-15 and had the same results. Perhaps you should contact tech support and report this as a bug.

This should be easy to do by manually adjusting the roof perimeters. Post a plan and I will have a go at it.

Provided that there is no glass in the door.

I suggest that you post the plan file so that someone may look at what the actual problem is.

In creating an as-built set of plans, the existing basement windows are just under the ground floor sub-floor. This is pretty common in my area so that the first floor can be close to the grade limiting the number of stairs to reach the ground floor, and at the same time saving the cost of window wells. I am perplexed on how to model these that doesn't end up with cutting the floor above. I couldn't think of a way to do this that didn't involve a hole i the platform, then using a material area to repair the hole. Any ideas? 5 Bruntsfield.zip
