Autodesk Revit材质转换为标准材质Stardard的方法

在讲autodesk Revit  模型文件转换为VRML（.wrl）过程中发现，材质丢失了。因为导出为wrl的材质是不能识别autodesk的材质。所以只能将autodesk材质转换为标准材质。

手动修改吧太复杂了，所以重新写了一个 转换 函数。将所有材质，包括多维子材质转换为标准材质。问题解决。

fn  converMat obj =(
colorSrc=color 200 200 200
try(
colorSrc=obj.Material.Generic_Color
)
catch()
try(
colorSrc=obj.Material.Concrete_Color
)
catch()
try(
colorSrc=obj.Material.Wall_Paint_Color
)
catch()
try(
colorSrc=obj.Material.Ceramic_Color
)
catch()
try(
colorSrc=obj.Material.diff_color
)
catch()

try(
colorSrc=obj.Material.Masonry_Color
)
catch()
try(
colorSrc=obj.Material.Metallic_Paint_Color
)
catch()
print colorSrc

obj.Material=Standardmaterial ()
obj.Material.Ambient =colorSrc
obj.Material.Diffuse = colorSrc

   )




   for obj in selection do

   (
print obj.material





if (obj.Material != undefined and Classof obj.Material == StandardMaterial)then
(

)

else if(obj.Material != undefined and Classof obj.Material == MultiMaterial)then
(
num=1
for  subMat in obj.Material do(


if(Classof subMat==Autodesk_Material) then (
colorSrc=color 200 200 200
try(
colorSrc=subMat.Generic_Color
)
catch()

try(
colorSrc=subMat.Concrete_Color
)
catch()

try(
colorSrc=subMat.Wall_Paint_Color
)
catch()

try(
colorSrc=subMat.Ceramic_Color
)
catch()

try(
colorSrc=subMat.diff_color
)
catch()

try(
colorSrc=subMat.Masonry_Color
)
catch()

try(
colorSrc=subMat.Metallic_Paint_Color
)
catch()

print colorSrc

obj.Material[num]=Standardmaterial ()
obj.Material[num].Ambient =colorSrc
obj.Material[num].Diffuse = colorSrc
)


num=num+1  


)



)

else if(obj.Material != undefined  and Classof obj.Material==Autodesk_Material)then
(
converMat(obj)



)
