Revit LT - Custom Roof

[bchaney0927]

Hello Mentors and Colleagues,

I like using Revit LT.  It gets the job done for about 99.999999999999^99% of the things I want to do.  

After about probably 5 years with it, I'm hitting a snag with an idea that I have for a custom roof, and I am wondering if you have any ideas better than the cumbersome fiddle-faddle  of linking a v8 skp and going back and forth whenever some adjustment is necessary.  (in the long run might be worth it, but for now...)

*forum won't let me attach* Roof Experiment.skp = just the roof its self

*forum won't let me attach* Roof Experiment 1.skp = exploded massing model

Roof Experiment.rvt = 2019 rvt with revit walls and linked skp for the roof.  Walls are customized for alignment with the skp roof. 

Right now, it looks like the thing to do is link the skp "roof experiment" and manually align things.  The trouble I see is that it isn't a roof entity/category/whatever in the Revit model.  I'm not sure why that might be an issue, maybe something like trying to add an elevator headhouse or plumbing vents or skylights (probably the big one, skylights)

So, it would be great to hear ideas from all of you.  I'm sure there's some kind of slap-the-forehead thing that I'm missing, but that's a fun thing about discussion forums, right?

Thanks!

Why not create the roof using Revit geometry (e.g. using the Roof tool)?  

[loboarch]

That roof falls into the .1% of things you can't get done with Revit LT. This can be done with not too much trouble in Revit with slab shape editing or in a pinch could for sure be done in massing or in-place modeling. All of those are tools you don't have access to in Revit LT.

What happens if you open a Revit Project with a Roof By Mass Face in it?   Are you unable to manipulate it? 

[loboarch]

The roof planes get shape handles but are otherwise pretty much "dead" elements. So you could change the extents of the slabs but little else.

Do you have the roof opening tool in Revit LT?

I was able to get close by making two separate roofs and using the Roof Opening tool. you might have more luck if you understand the angle better than I do
