Double pitched skylight

Hi community! My first post here 🙂

 

Does anyone have experience with double pitched roof windows/skylight? I did not manage to solve within the built-in library and it is hard to find any bim object online, as these come mainly as rfa. Is there any workaround I am missing or is it just hand modelling here?

 

Thanks

Your attached example is probably more easily modelled in bits. A simple hole in the roof. Either a single plan roof or a pitched beam for the finishing on the inside and maybe a curtainwall element for the skylight.

 

The skylight tool will not be able to span two different roof planes.

Something you can do to model your own dbl pitched skylight like this is to import the best .3d model of it you can find and then if needed, convert it into a morph, delete what you don't want, add to it what you need, save as and object and use that.   But for that specific skylight I would just model it with Archicad elements.

Thanks guys,

I modelled a simple one using morph. I found velux .gsm https://www.bimobject.com/en/velux-c/product/ridgelight double pitched, but not for the slope we have. Other nice products were for revit only.

Skylight Ridge 25 works pretty well to get what you want if you need to tweak it a bit as a morph.  It could be modeled as roofs too for the sake of easy pitch editing ?   https://www.youtube.com/watch?v=uW9ENFqbNGU

the trick is to use a tiny flat roof that can not be seen to place the skylight 🙂 .  Place it on a big flat roof first, then make that roof tiny.  Move the main roof to fit the skylight, then move them together back into the proper location, other wise it is a bit tricky to make it fit.

Wow, thanks Steve. This looks fun 🙂

Unless there are so many skylights that you need them to Marker ID's, I would model those skylights as Beams, even the glass as beams. Easy to change pitch that way.  Your detail marker can reference the manufactures .dwg or .pdf.

EDIT! Sorry! Already found the description below the picture 🙂

 

 

Ok, total rookie here :D...how do I position the skylight ridge along a roof ridge line? It always snaps to the roof plane only. sScreenshot 2021-10-08 at 10.06.31.png

@enjoystick1 You need to create an independent single plane horizontal (0 degree) roof and associate the roof light to that piece of roof to make it work.

@enjoystick1 I am a big fan of the new beam tool. You could create 3 complex profiles e.g. Gable ends, section through glass & section through mullions. The profiles could be either full width or just one side and then mirrored. Form a segmented beam using the three profiles and edit the roof shape to suit the beam on plan.

Depending on requirements you could add other profiles for a more detailed model.

Yeah, that's also true! Thanks a ton 🙂

You could also create the Skylight using the Curtain Wall tool. You could cut a Section through the Roof where the Skylight should be, and then you could place a Curtain Wall in the Section, in which case the Curtain Wall will be composed of two segments and will be extending perpendicularly to the section plane.

Using the Curtain Wall for this has the advantage that you can define a pattern for it so it remains parametric. Plus you can set different profiles or sizes to its various boundary and frame segments.
