Complex roof

[archkre]

Where can I find a good tutorial on a complex roof, with multiple bond beam heights, mixture of hip/gable/dormers, like the homebuilders like to make to kill us, please?

Thank you

Don't know of any good tutorials, may I suggest just using extruded polylines and the 3d solids editing tools such as union and slice. Then to lighten the face count delete faces.

 

Start with the main (common roof) and draw polyline slab section/s and extrude. Continue on to the dormer type roofs and extrude past the common roof and do a 3d slice using 3 points from the common roof slab to create the valley cuts (intersections). You can use the polylines to modify the walls creating gables and the proper wall to roof intersections. The hip roofs can be created from a common roof (triangular section) merely by drawing a polyline at the proper pitch from one bottom edge of a roof face, then using the 3d slice with 3 points, 2 pts from the polyline and one from the far pt of the common roof face. Then just delete the bottom face of the solid.

 

Using the roof & slabs on a complex roof system can be quite challenging, usally the best option is just to go for solids or 3d faces.

 

 

Hope this is of some assistance.

Thank you very much, but I am trying to speed up this roof generation process thru adt2004 roof-slabs features.

Thru coventional modeling , roof generation is taking long hours, almost 50% of the total modeling time, including environment.

My target is to decrease that incidence to a 20%,..will I be able?

For very fast speed, use Desktop or Sketchup. Export gemoetry - done. You can loft an overhang (eave) profile in Max later on to get more detail.
