Bi-directional shape/attribute communication
Hi folks,
An interesting by-product of my little experiments from this thread ... thanks Cheryl !
Minimum distance based on axis / world orientation ?
With a bit of hacking I managed to get different shapes and rules to talk to each other (passing level numbers in this case) with just a single Attribute Connection Link - shapeID.
This is just a simple proof of concept where;
- Initial slide (everything separate) shows each podium's and tower's number of levels.
- Podiums (red text) report on total number of levels - itself plus all towers placed on top of it.
- Towers (blue text) report on total number of levels - themselves plus all towers placed on top of the same common podium.
So essentially podiums communicate one of their attributes to the towers, and towers communicate one of their attributes to the podiums.
Podiums and Towers have different rule files applied, with only a single Connect Attribute link applied to both - a unique shapeID. They are not linked in any other way nor do they share common attribute names etc.
It's all handled via occlusion queries.
Heya David,
I'm so glad you like/ appreciate this.
For a second there I thought that maybe I created something that's easily achieved in other ways in CE 
It's a little clunky, but let me just clean it up and comment things and then it's all yours.
With a small addition from Esri to occlusion queries (not sure if it's possible however) this could be way more efficient, neater and easier to manage. For us it was to enable simple communication between podiums and towers, and to report on the building (with separate shapes and rule files) as a whole. I'm sure you'll think of way more interesting things to do with this.
Hi Tim,
Glad you like it. It's still very much a hack but a good and useful one
I have an intense week or two coming up but I'll see if I can shoot you something across after that.
Cheers.
