Roof edge + attached wall

Hello.

I've been struggling with a best practice for my roof issue.

What it should be.

The insulation part of the roof is between the limestone walls. The rooftile still has a little overlap which makes the roof edge slim.

How I did this: by creating seperate roofs. The insulation part are 3 seperate roofs. The tiles are a roof on it's own.

Problems I bump into: the roofs are not 'locked', a change in the insulation thickness doesn't mean the tiles move along. Furthermore aligning these roofs is difficult

What would be great.

If I could make only 1 rotf footprint which has

-the insulation part,

-thin roofegde

-limestone are cut out so stop after the insulation part.

What happens if I do this right now.

- limestone is attached to bottom part of roofpackage.

- roofedge is not slim. Insulation doesn't stop.

My question:

How do you do this?

You bring up an interesting questions and one that I struggled with when working in production. Here’s how I approach it.

Can the budget of the project allow you to create multiple roof elements that make up the whole?
If you create the roof as one element with several layers in its structure why can’t your detail to explain how it all works?

If the answer to 1 is yes, then model away, but you may have to add constrains on dimension to make sure the whole thing works as a unit and looks good in your drawings.

If the answer to 2 is you don’t want to do this, then I think you are over engineering your model. Keep in mind that you will not see any of your roof details at smaller scales, so all your hard work will be for nothing. I typically say “Let your details do the talking” but I have in the past models up each element and combined as a whole, but only on smaller projects. Did you consider using the conceptual massing tool, perhaps your results will look better, assuming its looks that count.

In any event I hope this was useful and thanks for postings
