SEO using door as operator and slab as target

[Durval]

Is it possible?
I'd like to insert a sliding door with a sill/frame bellow the level of the floor, that is, the sill elevation is smaller than zero.
Tried to set a SEO, having the door as operator and the slab as target of a subtraction, but it seems AC9 didn't like my operator (the door). If I select the wall as operator, the subtraction works, but only outside the range where the door was inserted...

You should be able to have the door sill with a negative height, and could use a slab or wall ( on a layer turned off) as your operator?

Yes, I could, but I'd rather avoid having to create another element for each door I insert, only for the solid operation to work.
Actually, the ideal solution would be if there was a way to make the GDL script of the door to perform the subtraction on the slab. But I don't know how, and if, this could be done.
A reasonable solution would be if the door itself could act as operator on the slab. Other object types can work as operators. Why doors can't?

Durval,

Try this: IF glob_context=43 THEN
"any SCRIPT THAT GENERATE 3D SHAPE AS OPERATOR"
ELSE
"ACTUAL DOOR 3D SCRIPT"
ENDIF

I'm afraid I didn't grasp your suggestion.
Just to test, I added the following lines in the very beginning of the door's 3d script:

 IF glob_context= 43 THEN  
   BLOCK 1, 1, 1  
ELSE  
!(actual 3d script)  
ENDIF  

Then I selected the wall in which that door was inserted, and set it as an operator (if I select only the door, AC doesn't allow it to be an operator), and the slab as target. But the BLOCK didn't show up, neither the slab was cut.

This is still very much an ongoing need!

I'm not fully fluent in technical English terms, but I'll give this a shot.

If you have your subfloor as a composite (either seperate or part of the structural floor) set as 'finish', if your doors touch the top of the subfloor, it will fill up the opening. Assuming the wall with the door is touch the structural floor.

If you have set up a sill option with the door, that is not thicker than the wall that 'hosts' the door, you should be able to see that sill just fine in sections. If the sill is supposed to also cut the structural floor, that seems to me that it would be something that can't actually be built that way.

Thanks Erwin.

A representation of the attached is the desired outcome.

However, in section, merely dropping the sill below the wall and into the slab does not result in a clean outcome. Sill and jamb flanges often do poke beyond wall width as well.

This method also does not form the associative rebates in the slab edge that should appear in the IFC structural elements model (i.e with windows turned off) that is exported to the structural engineer (for larger projects)
