Roof type by shapefile attribute

NavidMoghadam

Hi everyone,

I have the roof type as an attribute in my footprint (shapefile attribute table) and I want to assign the roof type directly in the CGA rule, not in the inspector. For example, all my gable roof footprints have ''41'' as the value in that field and I want the CGA rule to generate gable roof for any building footprint with the same value without doing it manually in the inspector.

Thank you

Use a case. This should work..

attr RoofValue = 0

@StartRule
Lot -->
&nbsp;&nbsp; case RoofValue == 41: generateRoofGable
&nbsp;&nbsp; else:&nbsp;generatePyramid

generateRoofGable -->
&nbsp;&nbsp; roofGable(30)
&nbsp;&nbsp; color(1,0,0)

generatePyramid -->
&nbsp;&nbsp; roofPyramid(30)
&nbsp;&nbsp; color(1,0,1)<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Hi Navid

Check here : GIS Diven Building.cga and building footprints

You have to create or to modify a cga file. To see some samples get the Tutorial https://www.arcgis.com/home/item.html?id=1746ca6086dd41a49549541438a50531

You will need to choose one attribute on your shapefile to put the information about the roof type and use something like :

attr Roof_Form = "hip"

Roof -->
   case Roof_Form == "shed"       : ShedRoof
   case Roof_Form == "pyramid"       : PyramidRoof
   case Roof_Form == "gable"       : GableRoof
   case Roof_Form == "hip"           : HipRoof
   case Roof_Form == "half-hip"   : HalfHipRoof
   case Roof_Form == "gablet"       : GabletRoof
   case Roof_Form == "gambrel"       : GambrelRoof
   case Roof_Form == "mansard"       : MansardRoof
   case Roof_Form == "gambrel-flat": GambrelFlatRoof
   case Roof_Form == "mansard-flat": MansardFlatRoof
   case Roof_Form == "vault"       : VaultRoof
   case Roof_Form == "dome"       : DomeRoof
   case Roof_Form == "saltbox"       : SaltboxRoof
   case Roof_Form == "butterfly"   : ButterflyRoof
   else                           : FlatRoof
