Emergency roof help needed

[dave.buckley]

Guys having major difficulty creating the roof in the attached image. The image is from google earth and is the only reference i have to work from

really struggling, i may be able to get heights of slopes etc if needed

i just don't know where to start as i am relatively new to revit, i believe i may need to start with footprint roof and also slope arrows, but i don't know how to use slope arrows properly and also where i would put them, as i am not an architect and my architectural terminology is severly lacking. i am learning tho

any help is much appreciated. i also have the revit file if anybody needs it

Dave:
Draw the big roof at the bottom as a square. Let's pretend north is up.
Each sketch line of the roof represents the roof boundary in plan- the footprint.
The east and west lines control the roof's pitch. Select those and you will be able to check a box for "Defines Slope". Once that box is checked, you can set the slope. Use "8" for 8:12 slope. Do this for east and west sketch lines, then click "Finish Roof".
Make the roofs perpendicular to this first roof in the same manner. For the hipped portion, you will have "Defines Slope" checked for the north, east and south walls. I would maintain a constant slope to begin with, for instance 8:12.
To join the south roof to the middle roof, there is a special command called "Join/Unjoin Roof". The sequencing is pretty straightforward. You click the edge of one roof, then another, and the roofs will join.
Good luck. After you've done these three, hopefully your confidence will give you a boost to tackle the dormers.

cheers for that, however i think i've made a pretty good stab at it.

this is by no means correct but all the slopes are in the correct places. only problem i am having is getting the two roofs that are highlighted to cut together. the join roofs tool will not work

then once i have done that bit right, i need to get the right overhang amounts for each part of the roof

lol... So i know its not your design, since its already built, but uh... Hows the water getting out of that vallye on the roof? Or are you modeling it because its rotting away? :)

[dave.buckley]

its actually our office building and my bos has asked me to model the offices, its an old house that has been built for years yes :)

but all he gave me was the google earth image.

not the simplest/easiest/best design i must agree :) not that i know anything about designing roofs
