roof issue

Anonymous

hi guys,

have been banging my head off the desk all day trying to figure out to make a curved pitch roof,however the roof tool just doesnt seem to be capable of what i am asking.

essentially i want to put a pitch roof on a semi circular building.....the best picture i could find to demonstrate is this picture (see attached). The shape of the descending seat is essentialy what i want the roof to do in my model.

the problem is that the pitch is not straight, it must adapt to match the curvature of the wall....anyone know how to accomplish this?

You don't need to use a "Roof" for a roof like this.

Try the Profiler to make the roof. Use SEO to fit the walls to it.

Options:

1. Curved profiled wall (best)

2. Segmented roof pitches (wedge shapes in an arc)

3. Write a library part (only worthwhile if you need to add special functions/behaviors and have plenty of time on your hands)

right another of my rather newbish questions:

i want to trim a wall to roof height but it is being intersected by two roofs and i want it to trim to the higher one and not the lower one-can this be done or do i have to redraw the lower roof after trimming?

Select the upper roof and the wall together and trim. Since you are not selecting the lower wall the program knows you only want to trim the higher one.
