Recursive tower has extra walls

LoringTupper — Mon, 20 Jan 2014 19:26:45 GMT

I've got a CGA rule that creates a building that has a pedestal and 2 towers on top of the pedestal. The towers are set back from the edge of the pedestal and then extruded, they look okay as well except that duplicate walls are created that extend from the edge of the pedestal, as in the image below:

[ATTACH=CONFIG]30640[/ATTACH]

the code I used is below, can anyone tell me what I did to cause this phenomenon?

Pedestal -->  extrude(world.y, ((Num_Pedestal_Floors * Upperfloor_Height) + (Groundfloor_Height - Upperfloor_Height)))  PedBuildingVolume3D  PedBuildingVolume3D -->  case (Groundfloor_Height != (Num_Pedestal_Floors * Upperfloor_Height) + (Groundfloor_Height -

So I've solved the extra wall issue but now I've got duplicate towers, one set that is extruding from the top floor of the pedestal but also a set that extrudes from the top of the first floor of the pedestal. I thought that the split only effected the current polygon?

The model now looks like the following:

the code now looks like this:

Hi !

You still have an awful amout of code duplicated. I'm sure you can still erase lots of that. Especially in relation to those reports.

I know it's difficult to track this down ..

This here may help you if you've not seen it already :

Also, make absolutely sure you use the Model Hierarchy to track these things down.

Check here :

Let me know how you progress !

Thanks for the feedback Matt.
I did manage to solve the problem, I was missing a component operation when I branched from the pedestal to the towers.

As for the duplicate code, I'm not sure how I can clean it up, I'm dealing with a report that requires that I report on the 4 floor use types as well as having the ability to independently modify the floor use makeup of the pedestal and each of the 2 towers.

Re: Recursive tower has extra walls

MatthiasBuehler1 — Thu, 23 Jan 2014 13:12:45 GMT

Ok..

well, if you need a lot of such precise control, the code may get a bit complicated.

But in general, I'd try to never copy rule calls, e.g. like for reporting.

e.g. instead of calling the report rule from within every case statement, just call it once in the next rule.

What may help is to create so-called generic attributes. That way, you can pass everything down without rule parameters and can work with less case statements.

Pumping all geometries and all volumes through the same logic streamlines the code a lot..

A lot of theory.. sorry. 🙂

I'd like to help you out with coding this more properly, but I'm swamped with work right now .. 😞

a bit cooler/more automatted reporting :
Note that this automatically accumulates the totals in Vol & GFA too.

Reporting -->     report("Vol." + myUsageAttribute, geometry.volume)     report("GFA." + myUsageAttribute, geometry.area(bottom))

Re: Recursive tower has extra walls

LoringTupper — Tue, 28 Jan 2014 20:49:04 GMT

Thanks for the tip Matt. Using attributes for the report items does indeed clean up 3/4 of the code I had be using for reporting. This is something I'll use from now on and, if I get a chance, I'll go back to previous rule files and clean them up as well.
Thanks again, good tip!
