Cannot edit roof plane w/o losing dormer

[Crashmo]

I would like to add a cantilevered balcony to a large shed dormer.  Essentially the dormer acts as a room within the second story.  The deck will draw just fine, but anything I do to the roof planes completely eliminates the dormer walls and roof.  I would like to break the roof planes to meet the sides of the balcony so as to not cover the balcony deck.

 

It is an automatic dormer so I get the warning "Cannot build walls for dormer here because other walls are in the way." 

 

Anything I want to change on the rear roof plane results in the entire dormer reverting to the original roof.

 

Any help appreciated.

Consider drawing in your own dormer and not using the automatic ones.

 

With Pro, you have control of the roof.

I think in this situation you should post the plan.

 

Something about the picture ain't right.

If you edit the component parts of a dormer improperly of course you will destroy its usefulness, as a unified object (Dormer Tool) the placement of the dormer is critical. If you really need to edit the dormer it should be "exploded" into its parts ( roof plane, hole in the roof poly line, Walls) and once exploded carefully rearrange  the parts manually until you  get the outcome intended. It is not a difficult process but is exacting and unforgiving when missteps are taken.

David,

 

Thank you for that suggestion.  I didn't think of exploding the dormer because I did not want to edit the dormer.  But... it worked.  Now the main roof no longer cuts through the balcony.

 

Thanks to everyone else--I did consider all of those options.
