Is it possible to add overhang to a pyramid roof and a shed Overhang?

Question

Hi all.

Is it possible to add overhang to a pyramid roof and a shed roof?

Like the overhang attribute in a Gable roof and  Hip roof.

Any suggestions?

Here's some ancient code I wrote once to make a "true" overhang, unfortunately it only works properly for buildings with equal width and depth due to the trig used to calculate the y-offset. You could always eyeball it, though. Or just change it to have a floating "tent" hovering close above the structure. attr overHang = 5 attr roofAngle = 30 @StartRule Lot --> extrude(1) s(20,10,20) center(xz) comp(f){top: Roof RoofOverhang| all: NIL.} Roof --> roofPyramid(roofAngle) RoofOverhang --> s(scope.sx+overHang*2, scope.sy+overHang*2,'1) roofPyramid(roofAngle) center(xz) split(y){overHang*tan(roofAngle): Overhang | ~1: NIL} Overhang --> t(0,-(overHang)*tan(roofAngle),0) comp(f){top: styleOverhang | bottom: NIL}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

This isn't always perfect, but it's a trick I use and works well - I scale up the roofplane and then center it. /** * File: Geonet_Overhang.cga * Created: 27 Sep 2017 15:58:51 GMT * Author: Devin Lavigne */ version "2017.0" #THIS IS A PERCENTAGE @Range(1.0,2.0) attr overHang=1 @Range("Shed","Pyramid") attr roofStyle = "Shed" @StartRule Generate--> extrude(10) comp(f) {top:RoofPlane | side:Wall} RoofPlane--> s('1*overHang,'1*overHang,'1) center(xy) BuildRoof BuildRoof--> case roofStyle=="Shed": roofShed(10) else: roofPyramid(40) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
