All,
I know everyone is getting tired of hearing from me about roofs, but I just can seem to figure it out in Revit. In ADT2006 I can adjust the individual roof planes to get exactly what I need, same thing in Chief Architect.
I am trying to learn Revit and am practicing on a couple of "canned" designs. These designs are popular styles here in the Atlanta market. I have attached a rendering of a current practice project that I am struggling with.
Can someone tell me what is the best method to creating a roof like that attached:
1. Should I do roof by footprint, by face, etc.?
2. Should I use slope arrows?
3. Should I draw the roof in ADT and bring it in?
Thanks for everyones patience while I learn this last aspect of Revit.
DJ Landreneau

one thing to consider is:
Highlight the roof in question.
Select the edit button in the header bar above the drawing.
roof outline should turn purple.
You can then select the appropriate line and edit it through the properties dialogue box.
You can pick "pitch" "height from plate", etc.
Also look for the roof tutorials: there's one that calls itself the "must knows"

Based on what you are saying it sounds like I need to create multiple roofs for this type of construction. I have been creating one roof by picking all the exterior walls on the house.

actually you should be able to create roof by footprint or however you choose to do so.
and then use the edit tool like i described to modify individual roof plans.
Atleast i haven't had any problems doing so.

there's also an opening tool under the modeling tool bar that you can use to further modify your roof in terms of taking chunks out with messing with your ridge lines

Here is the East Elevation from the house I'm working on. How do you get the roof to pitch up higher. The ridge at the left in the circle should be higher and the ridge at the right should join into the hip.

Hey djnadreneau,
Yeah I feel your pain regarding the roots, they are a little akward. The first thing to avoid in my opinion: picking walls to determine the boundary. We've found that sketching is always the ticket, regardless of whether you're drawing ceilings, roofs or whatever.
We find that complex roofs will inevitably be made from more than one structure, then anything is possible. You can join roofs that overlap and align the surface patterns on each face to each other to appear to be continuious.
ICON: When you say that you usually only need a single footprint to make roofs, have you mamanged to overlap them (like when one roof extends over another, like the gables-within-gables on djnadreneau's first pic)?

True I don't always use only a single footprint.
I also use multiple roofs for the gable in gable you referenced as well as roofs at different plate heights.
I'd just like to say that I've only worked on about fifteen roofs so far and none have been what you might call real complex. So I still have a lot to learn about the subject. I've gotten by so far with selecting walls and manipulating the roof planes and heels through edit and properties.

HISDIRT,
Other than trial and error how do you go about figuring how to break up the different roof parts?

ICON: But you are right, the bulk of your roof does tend to consist of the one footprint.
djlandreneau:
haha, there are other ways to learn Revit other than trial and error? Unfortunately this is pretty much it... basically go as far as you can with one footprint untill it stops acting as you want it (ie, wont slope correct, or you cant specify an accurate plate height), then supplement with additional roofs.
If you could post a roof plan, people on here can draw over it what the foor sketch (complete with purple lines) should look like, which will solve all the problems. 'Export the current view' and post the .jpg up here (like you've done previously) and we'll sort you out.
Does anyone have better advice than this? If there is an invincible method of Revit roofing that you know of, let us know...

hi djlandreneau,
this mini-clip from DGCAD on roofs may help shed some light on the subject
also if you have the revit subcription, under the Autodesk University 2005 material there is posting that deals with creating all roof types.

Here is the first floor plan.
I purchased the DGCAD tutorials, but unfortunately all of the tutorials, DGCAD and others, only cover simple roofs.

djlandreneau:
I also downloaded the dgcad videos and talked to dg about
how there weren't any instruction on doing complicated roofs.
He did this special mini-clip of my design in for VARYING-ROOF-PLATES
If this video doesn't answer all your questions maybe you can e-mail
him like I did since you bought the videos.
