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

You are the best! Thank you so much, your fix is gonna save me some real headache (hopefully, for other users too). And sorry for calling you personally. I hope it didn't take you too much time!

Hi Mike96,

No it's not theory that work like this in my Archicad. The images are real screen consecutive shots.

Not sure which library update you are using in AC28, but I am on Update 1 and the maximum pitch is limited to 5 less than the roof pitch.

Are you placing this object on the roof with the sky light tool rather than just as an object?

It should then automatically read the roof pitch and adjust to suit.

I'll second Karls sentiment.
the only time I've used the dormer parts was for a place holder for an eyebrow attic vent in an as-built model. These kinds of parts fall in the same vein as the stairs, railings, curtain walls, and in many cases doors and windows. They work, when 'good enough' is the target. 
In residential work, I have both sides of the spectrum. For spec home/tract home projects, where I need to get from preliminary design to permit docs in under 20 hours, good enough is all they get from me. But I work with architects doing $x000/sq ft homes... and good/close enough is NEVER going to cut it; even at early design.

Barry, as I already said, I tried both, knowing that skylight is the way to go.

Tested in Archicad POL + INT, from 25 to 29 (3000). In all instances pitch is limited to 35 deg, no matter how I place the dormer.

Everybody here just sayin how it SHOULD behave, but has anyone actually tested themselves?

Only Jaime took time to recognize the issue and actually fix it, although I believe GS should do it themselves.

Honestly, I think at this point, this thread is going nowhere, with people posting opinions about what is better workflow, instead of focusing on the matter of the problem. I marked it solved already.

When I place the dormer with the sky light tool, the shed roof pitch is limited to 5° less than the actual main roof pitch that you are placing it in.

So please make sure you are using the sky light tool and not the object tool to place the skylight.

I also see it is locked at 35° when using the object tool.

Using the skylight tool, it will also cut a hole in the roof automatically and it will be associated with the roof, automatically reading the roof pitch and adjusting the allowable settings to suit.

If you use the object tool to place it, this will not happen.

Trust me, I think after using Archicad for nearly 30 years, I know what I am talking about.

Most of the time anyway. 😉

I am using the AUS version, but I can not imagine it is any different to the POL version in this regard.

It certainly is no different to the INT version.

Well, there is the object in the file you shared at 50 degrees... I cannot think of anything way something could limit it externally... @Jaime-airc_digital, did you actually manage to replicate the issue?

In the Original Post;

Yellow shows it placed as a skylight tool-selected and editable.

Green shows it as an embedded object

Blue shows that there are no other linked libraries.

I remember that when I moved from Archicad 22 to Archicad 25 there was a change in the way the Roof angle was treated in the skylight tool.

I had to change the approach to get the angles to work correctly on 2D symbols because "ac_roofang" no longer worked in the parameters script.

The Dormer Shed i managed to download was found on  BIM Components, was an Archicad 16 version from 2012, so it will require code changes to work post Archicad 23.

when Archicad 25 rolled out I had to ditch the "ac_roofang" variable because it always returned the default "40°" when dealing with parameter calculations i.e. values calculations.

when I test "Dormer Shed 25" placed as a skylight placed in a 70° roof

although the range says "-1 to 65" for my 70° test roof, when you type in the value "60" it reverts back to the default "40 - 5"  = "35"

keeps popping back to 35.

Today it is repeatable;

Although when I did the same test on Friday with the "Dormer Shed 25" i thought it worked with the slope of 65 being input, but today it didn't...

This is almost as annoying as the Photoshop 3.0 bug which crashed on Mac every time you edited brush sizes on even days of odd months in 1998...drove me crazy...then in 1999 the bug magically went away...

P.S. it was for the 2D symbol for skylights with Light shafts attached(the Velux range of skylights) i discovered the problem...

The problem I had was for the light shaft calculation for the top edge of the ceiling, and the position for cutting the ceiling slab edge on the upper edge of the light shaft need the roof angle to calculate it.

I need it to calculate the upper edge angle of the ceiling slab cut based on the roof angle & the Light-shaft angle & the ceiling angle (calculated by dragging nodes in section)

cut the hole in the ceiling slab based on the hotspots/hotlines of the orange shape, had to edit the angle of the edge of the slab so the lining would pass through.

and in section the light shaft is a perfect match for the ceiling hole

To clarify my post a little.

Even when placing with the skylight tool, the default shed roof pitch will be limited to 35° when you look at the settings before you place the skylight.

But once placed on a roof and it is associated, it will read the roof pitch and allow a shed roof pitch up to 5° less than the actual roof pitch.
