My clients would like to have their home have a roof similar to this:  image.thumb.png.0bab7c7b60c917084928c461a4a27433.png image.thumb.png.e2c030b570446f241db2ae6183a42c2d.pngimage.thumb.png.fdd3a6a53db098a96b7a59d16e053f14.pngimage.thumb.png.2235db68ffb3c6675c5a86959efa0a21.png

 

Problem is this house seems to be "L" shaped and theirs is extremely zigzagged to try to fit it onto a pie shaped lot and still have all the amenities they want.  Here is what theirs looks like. I will be removing the hip roof on the deck as it is supposed to be replaced with a concrete slab roof.  and the roof deck will be over the master bedroom area instead of to the front of the house.  

 

Here is a picture of the plan and elevation I was able to come up with.... and I have attached the x11 plan.  Anyone have suggestions???

The roof on the picture with the parapet walls is very simple to do, here's one way to do it

  • You can add another floor and remove all the typical things from the room settings, make it the height you need, four feet or less.
  • Put a roof over the new room, but stop the gable ends at the interior gable end walls, this will leave the two gable walls free
  • Lower the entire roof baseline to the desired height, this will drop the roof and extend the end gable walls, but they will be flat top
  • Copy and paste in place the roof you created, open it and change the surface and structure to the lowest dimension possible, use air gap for material
  • Uncheck all the framing stuff, fascias, gutters, etc.
  • Select the air gap roof and raise the baseline to the desired height of the parapets (this roof should be invisible in 3D) Change the line type so it is light and hide it in a layer.
  • Pull the end gable sections of the air gap roof past the two end gable walls, this will cut the flat walls to the shape of the air gap roof and it will create any attic walls needed.
  • Add a wall on the center of the roof ridge, now, the roof will stop the wall from passing through. (This is done on the new floor you created)
  • No room definition, no locate, balloon and attic checks on wall settings.
  • Pull the main roof to butt to the sides of the new wall so it passes through.
  • Raising or lowering the air gap roof will allow you to work the parapet height.

The flat roof can be done with another floor, make the walls railings, no ceiling and drop the height as needed.

(Roof planes can also be set to 0 for flat roofs)

Complex roofs and framing can be done in layers, creating one roof plane over the next adjusting settings for each one, manipulating the framing for each roof plane to create the trellis components.

Thanks for the great info Jorge!  With the given zigzag shape of building is this something that is able to be done where the outcome will look like the clients desired pictures?  If so, which walls would you make the gable parapet walls?  I am assuming there would have to be at least 3- 2 parallel with each other and  another perpendicular????

If your clients are really looking for a reproduction of the Modern twist to Dutch Caribbean Colonial featured at Ally's Beach you should probably first spend a serious amount of time learning the programming side behind the execution- even above trying to mechanically make it work in Chief.  Take it for what its worth, but you cannot "apply" this style to a design to get the outcome comparable to the examples.
