Texture Image of Asset

Question:

I have made simple part and assign to one face “Norman – One-Third Running” material from “Autodesk Material Library” . Then I have run VBA sample code “Write out all document appearances API Sample” of API help. The code result does not retrieve texture image. How it can be done ?

Solution:

The texture may be connected to the ColorAssetValue and FloatAssetValue, you can find the two asset values have HasConnectedTexture, but also a texture might also be in the TextureAssetValue. So now there are three asset value object can contain texture info.

• ColorAssetValue
• FloatAssetValue
• TextureAssetValue

In another word, the texture can be in different levels in the asset values, it depends on the type of the asset, like below asset type is Masonry, it has two textures:

Textures are at different locations in different types of asset, however there is not API that tells the type(Note, this is not Asset.AssetType), so we can only iterate all levels of the asset values to get the texture info.

Sub AssetTextureSample()
Dim oDoc As PartDocument
Set oDoc = ThisApplication.ActiveDocument
Dim oAppearance As Asset
For Each oAppearance In oDoc.AppearanceAssets
Dim oColor As ColorAssetValue, oFloat As FloatAssetValue, oTypeTexture As TextureAssetValue
Dim oValue As AssetValue
If oAppearance.HasTexture Then
For Each oValue In oAppearance
'TextureAssetValue
If oValue.ValueType = kAssetValueTextureType Then
Set oTypeTexture = oValue
Dim textureSubValue As AssetValue
For Each textureSubValue In oTypeTexture.value
Select Case textureSubValue.ValueType
Case kAssetValueTypeFilename
Dim filenameValue As FilenameAssetValue
Set filenameValue = textureSubValue
Debug.Print "kAssetValueTextureType " & filenameValue.value
End Select
Next
End If
'ColorAssetValue
If oValue.ValueType = kAssetValueTypeColor Then
Set oColor = oValue
If Not (oColor.ConnectedTexture Is Nothing) Then
Debug.Print "---------------------------"
Debug.Print oAppearance.DisplayName
Dim oTexture As AssetTexture
Set oTexture = oColor.ConnectedTexture
Dim oTextureValue As AssetValue
For Each oTextureValue In oTexture
If oTextureValue.ValueType = kAssetValueTypeFilename Then
Dim oFilename As FilenameAssetValue
Set oFilename = oTextureValue
If oFilename.HasMultipleValues Then
Dim sFiles() As String
sFiles = oFilename.Values
Dim i As Long
For i = 0 To UBound(sFiles)
Debug.Print "kAssetValueTypeColor " & sFiles(i)
Next
Else
Debug.Print "kAssetValueTypeColor " & oFilename.value
End If
End If
Next
End If
End If
' FloatAssetValue
If oValue.ValueType = kAssetValueTypeFloat Then
Set oFloat = oValue
If Not (oFloat.ConnectedTexture Is Nothing) Then
Debug.Print "---------------------------"
Debug.Print oAppearance.DisplayName
Set oTexture = oFloat.ConnectedTexture
For Each oTextureValue In oTexture
If oTextureValue.ValueType = kAssetValueTypeFilename Then
Set oFilename = oTextureValue
If oFilename.HasMultipleValues Then
sFiles = oFilename.Values
For i = 0 To UBound(sFiles)
Debug.Print "kAssetValueTypeFloat " & sFiles(i)
Next
Else
Debug.Print "kAssetValueTypeFloat " & oFilename.value
End If
End If
Next
End If
End If
Next
End If
Next
End Sub
