Trouble adding "dormer"

[David J. Potter]

You would be better served to think of it as a gable end as opposed to a dormer, the dormer tool will not be found to be workable to construct this. It is just a steep gable roof under which you have a room addition.

You either automatically or manually draw your gable roof. Then find out what the "ridge" height of the main roof is via its dialog box - ridge input box (find out what that value is).

The by manually applying that ridge value to your gable roof planes will determine the resulting pitch of those roofs.

Once those roof planes are properly located (height and pitch), you then finish your design of the room underneath those roofs. Since you have Pro with its manual roof tools, this is easily done.

By "easily done", I mean having precise dimensions applied to the virtual model, then having the precise locations of and settings to roof planes one can then plan and model such spaces. It is an exacting and methodical process done with a certainty of how each of the tools and objects are designed to work to arrive at a precision result. This arrived at by through study followed by methodical practice.

I appreciate that you have provided photos and screen shots but as Jon has pointed out, there is still too much missing pertinent data missing to offer precise instructions (roof pitch of the existing house, full view photos of the existing house, an understanding of the house equal to yours (you have been there and we have not). No one understands this project better than you do and a few lines of text and photos does not equal what you understand.
