Relevant Storey

[DGSketcher]

I have an object which spans multiple stories. If I stipulate a specific range e.g Home & One Storey Up or even All Stories it displays as expected. If I use the Show on Relevant Stories option the object display becomes limited to the Home Storey only. How does GDL determine if an object is "Relevant" to a storey view?

Haha, I know, I know.... (tbh I always use Google to find something, forums search was also trash in the old forum. Remember the infamous "search term is too common"? 😂)

Yes, they are quite old. I think they might even the oldest of the "ac_" ones.

What's funny about this is that these parameters are to be set by the programmer. Most of the other "ac_" params are actually getting set by Archicad while the object is being placed. But I guess they are just commonly reserved for "communication" between the Archicad kernel and GDL, which can go both ways.

Ive wondered what they were for, but never thought to look them up in the gdl manual.  stoked you brought this up, going to make things nice for me lol

Ew... ac_bottomlevel changes the "zero" point of the object, but that's suppose to be my static pivot point...

Sounds like I have run into the save issue as SinceV6...

@Lingwisyer Isn't it just a 2D relevance test? You are just saying to AC that from the object origin continue to display the 2D script if the lower limit is below the floor plan cut plane and the upper limit crosses the storey threshold. I haven’t tested but I assume this would work the same with just a 2D symbol object, the 3D modelling is irrelevant apart from any Project2 use.

Or more specifically that the limits fall within the displayed storey as there is also overhead projection settings to consider.

ac_bottomlevel appears to change the Home Story Offset Value. Or more like the dialogue shows ac_bottomlevel NOT Home Story Offset of the origin. The outcome is that my pivot does not move but as the object rotates, this value changes so instead of being the elevation of my pivot, probably the most important information, it is the lowest point.
