Code for noise cancelling screen with overhang

AleksanderAStysiak

Hi 

I need to create a model for Hamborg style Noise cancelling screen. 
Im struggling with creating an angled geometry on top of extruded wall. 

Any advice on how to add the orange marked extension to the green extruded wall?

I would like to be able to control the angle. Screen are usually several meters long.

No worries, here's an alternative compatible with the 2023.0 version:

 

/*
 * File:    screen_with_overhang.cga
 * Created: 30/04/2024
 * Author:  Patrick Fontes
 
 # This rule assumes you have the wall footprint as the initial shape
 
*/

version "2023.0"

attr screenHeight = 6
attr overhangAngle = 45
attr overhangLength = 1
attr edgeIndex = 0 //this determines the edge from where the overhang hinges 

@StartRule
Screen -->
	extrude(screenHeight)
	comp(f){side: ScreenSides. | top: OverhangHinge}
	
OverhangHinge -->
	roofShed(overhangAngle, edgeIndex)
	comp(f){aslant: OverhangExtension | side : ScreenSides. | top: OverhangExtension}
	
OverhangExtension -->
	extrude(overhangLength)

 

Cheers.
