Roof tools again

[Anonymous]

Are the roof slabs & roof tools useful for anything other than cosmetics/ "dressing" for elevation?

I ask because when using section tools the roof isn't actually framed in, just kindof sits on top on the outermost exterior wall.

I'm sure that you guys will enlighten me as i'm just using this wrong, otherwise i don't understand why we'd have so much detail within the roof slabs or walls themselves like sheets, insulation, gypsum, etc. but the roof doesnt even correctly attach to plates.

Thanks for your help everyone!

sorry i'm not the brightest in the box 😕

Both are extremely helpful.  You are correct that they might've been improved if they would've either included or worked with a framing system.  I don't think I need to explain why they help though.  When I started as an architect, drafters had to work out the relationships between elevation and plan manually.  Reading a textbook on AutoCAD architecture might help.

The roof tools can be used for more than elevation creation.  It's really up to the user how much detail or style of detail they want in the model in order to  get the point across.  Below are two section styles of the same model.  Dynamic blocks or symbols from the detail palette can also be used to add detail. See <screencast> for an example.  I guess it depends on what you want from the model.

Well i'm definitely doing something wrong, this is what i always end up with -

It looks like you made a standard roof and cut a section which is not wrong. It's a start.   Based on what you are getting from your section, which parts are you wanting to change? As a start you can make a few changes as listed below.

1. Change the section style settings to remove hatch lines.

2. Change the elevation of the roof to -1 if you want a seat-cut.

3. Edit section linework for cleanup.

4. Add additional un-modeled linework as needed for detail.

Robert, you're the governor!

I was worried just dropping the elevation to model a notch was going to be the "wrong way"

I really appreciate your help! 

Thanks again guys

It's part of a much larger discussion: How much detail do you put in your model and how much in standard autocad.
It would be nice if everything was in the model but a large model with every detail can become very large file and become very slow to manipulate as you work.
I've come to a happy medium where the model only includes the big shapes and detail only needed for a section is added over it using standard autocad lines etc, or blocks, or dynamic blocks.  Footings are added in after, as they are not really needed for views.  I do focus on providing 3D coloured rendered images so anything above ground outside is represented in some way and I've found quick ways of adding detail.
The roof is a single object, I can add and offset lines to a section to represent rafter and roof cover. I can add autocad lines or blocks to add battens etc.  I wouldn't model roof strutting or hidden beams generally, easy to add over a section.  Sometimes modelling detail takes more time than it's worth, with little real return and it also means if a client makes changes, you have to remodel a bunch of things that weren't worth modelling in the first place.
I do add ceilings with cornice and floors (slabs) because they impact a rendering from outside (light bleed).

I do use the roof tool over slabs for roofs and I've learnt the heights to 'cut in' to a wall plate but they are overlapping. Since sections are done at same scale (1:100)  as elevations it's not going to be noticable.
I then prepare 2d sections at large scale 1:10 where I try to show the detail accurately, sometimes tracing over a section to get the placements correct.
