Lighting fixture object - cutting ceiling hole with SEO

[matjashka]

Hello AC experts,

I have created an object representing a recessed light -- see attachment (3D section). In order to cut the appropriate hole in the ceiling soffit, I need to use an additional cylinder to do SEO and later hide its layer.

Is it possible to include an "invisible" solid within the GDL object itself, so I could just use the object as the SEO operator? Or is it possible to automatically cut the hole without having to resort to SEO at all?

Thanks a lot!

If your object is to be placed in a roof, you can make it as a skylight object that will automatically cut your hole. However, if you are placing the object in a slab, this will not work (there is not solution in that case of which I am aware).

Looking for a similar solution for AC14 Library Lights. Using the Recessed Flourescent for example, when subtracting downward, only some of the elements from the part subtract the ceiling (ie. the lamps), so I am assuming the others (ie. the housing) were not actually solids to begin with. So how can I add something to this part that will subtract out a rectangle from the ceiling and will change if I change the size of the fixture?

Thanks

(I was looking at the thread upside down!)

I second Kevin's question. What kind of solution can we use with Library Recessed Lamps?
Do we need to write GDL code or use hard to mantain SEO in order to have automatic holes generated in dropped ceilings when using any kind of recessed lighting?
