Lifting the limitations of Dormer Shed library

[Mike96]

I've got a problem with the native Dormer Shed in Archicad 25 and 28. I think its maximum Shed Roof Pitch value (screenshot) is hardcoded at 35 degrees. This is highly impractical and illogical limitation, and it should be increased to something like 89 deg. Sadly, I can't edit GDL myself, so I'm hoping someone would be able and so kind to try fixing it.

I placed it as skylight but the issue is the same if placed as an object.

PS

Sorry for Polish UI but I don't think this will be a problem.

Attached test model. Should I upload PLA or is PLN enough? Anyone can also start from scratch, it's a super simple example.

Operating system used: Windows 10

@Jaime-airc_digital,

maybe you want to take a look at it? I saw you got some experience with GDL and dormers :]

In 25+ years, I’ve never used the dormer objects vs modeling the dormers structurally/fully.  The objects are cute for demonstrating Archicad but, in my view, have no place in producing meaningful construction documents and data reporting.

[Mike96]

Well, they certainly are not perfect for 2D documentation but sufficient for 3D presentation and that's what I need right now (and pretty often, too). I work with heritage architecture on a daily basis, producing both 2D docs and 3D models, and not gonna lie, these objects speed up roof modeling significantly, until... You need steeper roof.

Why even keep such libraries in database when they have such weird limits imposed? It's not like a feature missing, it's not underdeveloped. I don't know what the author had in mind: "hmmm, no one would surely use a dormer roof above 35 degrees, so let's make it a limit!" ?

Using objects to create complicated construction elements is not always the best decision.

Using a basic approach might take a liitle more time but sure it simulates the real construction with all the BIM advantages.

There is also this by b-prisma for dormers:

Judging by video demo (PDF manual link is broken), I'm not sure this will help me. And I need to be sure before spending money on another object. I've already spent some on objects that didn't help me. Do you use this object personally? Would you recommend is as applicable in my case?

Also, I appreciate y'all telling me what's the best decision / approach and what's not but I've been using Archicad, along with some other modeling programs, for almost a decade and believe me, I know the pros and cons to different workflows.

I don't care that much about 2D drawings or BIM advantages. I mostly produce 3D models, many of which never get turned into documentation or BIM compatibility is not required. In the end of the day, it's easier to manually fix a flat drawing than a model.

"Using a basic approach might take a little more time" already used too much of my time over those years, which wouldn't be a problem if Graphisoft took a little more care in creating their libraries. I see them as great yet not fully explored (I don't wanna say: wasted) potential. They are flawed but still extremely useful in so many cases.

As far as I understand, this is fixable and could be done once for all. One fix and no more annoyance for life.

[Botonis]

If you prepare just 3d models then obviously depending on libary objects sounds logical.

When you create analytical construction layouts, quantity extractions, cost calculations, static frame caclulations, and using strucural detail options, design options, graphic overrides etc. then objects don't always perform as expected....

Different needs, different workflow.

Yes, the limitation is a safeguard, but it can be removed... here is the link to the edited object.

You just need to modify the ranges from the parameter script and the hardcoded reset for the shed angle in the master script.
