Color pattern iLogic
You mean something like this?
iLogic (rule):
'Declare array list of appearances to use
Dim sColorList As New ArrayList
'Add appearances to list
sColorList.Add("Anodized - Blue")
sColorList.Add("Forest Green")
sColorList.Add("Magenta")
sColorList.Add("Yellow")
sColorList.Add("Dark Green")
'Set global references
Dim oDoc As PartDocument = ThisDoc.Document
Dim oCompDef As PartComponentDefinition = oDoc.ComponentDefinition
'Set reference to first rectangular pattern
Dim oPattern As RectangularPatternFeature = oCompDef.Features.RectangularPatternFeatures(1)
'Declarations
Dim i As Long
Dim oPatElem As FeaturePatternElement
Dim oFace As Face
Dim oLibAsset As Asset
Dim oLocAsset As Asset
Dim oExtrFeat As PartFeature
'Iterate through each pattern element
For i = 1 To oPattern.PatternElements.Count
'Set reference to asset in library based on name in list
oLibAsset = ThisApplication.AssetLibraries.Item("Autodesk Appearance Library").AppearanceAssets.Item(sColorList(i-1))
'Copy asset to document
Try
oLocAsset = oLibAsset.CopyTo(oDoc)
Catch
oLocAsset = oDoc.AppearanceAssets.Item(sColorList(i-1))
End Try
'Set reference to specific pattern element
oPatElem = oPattern.PatternElements(i)
'Check if first pattern element is to be colored
If oPatElem.Faces.Count = 0 Then
'Get source extrude feature of pattern
oExtrFeat = oCompDef.Features(oPattern.Definition.ParentFeatures(1).name)
'Iterate through all faces of the pattern source feature and color them
For Each oFace In oExtrFeat.Faces
oFace.Appearance = oLocAsset
Next
'Or if other pattern element is to be colored
Else
'Iterate through all faces of the selected pattern element and color them
For Each oFace In oPatElem.Faces
oFace.Appearance = oLocAsset
Next
End If
Next
Please note that:
- I hard-coded the first (and only) pattern in my test model in line 18.
- There's no error handling except for copying the asset to the document.
Many thanks for your answer, but my problem is the following:
I have an extrusion for the load and one for the pallet in the first row and also an extrusion for the load and one for the pallet in the second row. Then I have a pattern for one rack unit in the front (pattern 1) and one in the back (pattern 2). Then I have a pattern for the rack units (pattern 3). What I want to do is color all pallets in one color and all loads in another color.
That's the way I would need it: All loads have one color (for instance green) and all pallets have one color (for instance brown). The whole extrusion should have the color, I only colored the big visible surfaces.
The pallet and the load are two different extrusions (not solids, because I need to mirror and remove the original)
If I color the pattern, pallet and load always have the same color, but they should be different.
Ok it is a bit tricky. Need to pattern as solid, not feature.
Feature will make them same colour.
I seem to be one step behind @Frederick_Law every time on this one 😀
But I think he is correct, in that if you set the color overide on the features to be patterned, then the pattern picks up the colors and you don't need ilogic for this
Here my original solids are colored as shown, and then the patterns are made so that they create new solids ( so I end up with 48) , and each new solid follows the original color of the feature.
