I would like to change the layers in a drawing based on a part's Appearance. I have found iLogic code to do it based on the part's material but then the physical properties of the part would not be correct. On the same layer some parts are plastic some steel and some aluminum. My end goal is to comply with national CAD standards and the layering convention established by the Army Corps. Ideally the code would be able to also tell the difference between line types and assign different layers to them (E-POWR-PANL and E-POWR-PANL-HIDDEN)
The code I am using is below, it works but only gets me part of the way.
Sub Main drawDoc = TryCast(ThisDoc.Document, DrawingDocument) If (drawDoc Is Nothing) Then MessageBox.Show("This rule can only be run in a drawing,", "iLogic") Return End If ChangeLayerOfOccurrenceCurves() End Sub Private drawDoc As DrawingDocument Public Sub ChangeLayerOfOccurrenceCurves() ' Process the occurrences, wrapping it in a transaction so the ' entire process can be undone with a single undo operation. Dim trans As Transaction trans = ThisApplication.TransactionManager.StartTransaction(drawDoc, "Drawing Layers by Materials") Try For Each dSheet As Sheet In drawDoc.Sheets For Each drawView As DrawingView In dSheet.DrawingViews ' Call the recursive function that does all the work. Dim docDesc As DocumentDescriptor docDesc = drawView.ReferencedDocumentDescriptor If (docDesc Is Nothing) Then Continue For If (docDesc.ReferencedDocumentType <> DocumentTypeEnum.kAssemblyDocumentObject) Then Continue For Dim asmDef As AssemblyComponentDefinition asmDef = docDesc.ReferencedDocument.ComponentDefinition Call ProcessOccurrences(drawView, asmDef.Occurrences) Next Next Catch ex As Exception trans.Abort() Throw ex End Try trans.End() End Sub Private Sub ProcessOccurrences(ByVal drawView As DrawingView, _ ByVal Occurrences As ComponentOccurrences) ' Iterate through the current collection of occurrences. Dim occ As ComponentOccurrence For Each occ In Occurrences If (occ.Suppressed) Then Continue For If (occ.Definition Is Nothing) Then Continue For ' Check to see if this occurrence is a part or assembly. If occ.DefinitionDocumentType = DocumentTypeEnum.kPartDocumentObject Then ' ** It's a part so get the material Dim subDoc As Document = occ.Definition.Document If (subDoc Is Nothing) Then Continue For Dim partDoc As PartDocument = subDoc Dim materialName = partDoc.ComponentDefinition.Material.Name ' Get the TransientsObjects object to use later. Dim transObjs As TransientObjects transObjs = ThisApplication.TransientObjects ' Verify that a layer exists for this material. Dim layers As LayersEnumerator layers = drawDoc.StylesManager.Layers On Error Resume Next Dim newLayer As Layer newLayer = layers.Item(materialName) If Err.Number <> 0 Then On Error Goto 0 ' Copy an arbitrary layer giving it the name ' of the material. newLayer = layers.Item(1).Copy(materialName) ' Set the attributes of the layer to use the color, ' have a solid line type, and a specific width. ' newLayer.Color = newColor newLayer.LineType = LineTypeEnum.kContinuousLineType 'newLayer.LineWeight = 0.02 End If On Error Goto 0 ' Get all of the curves associated with this occurrence. On Error Resume Next Dim drawcurves As DrawingCurvesEnumerator drawcurves = drawView.DrawingCurves(occ) If Err.Number = 0 Then On Error Goto 0 ' Create an empty collection. Dim objColl As ObjectCollection objColl = transObjs.CreateObjectCollection() ' Add the curve segments to the collection. Dim drawCurve As DrawingCurve For Each drawCurve In drawcurves Dim segment As DrawingCurveSegment For Each segment In drawCurve.Segments objColl.Add(segment) Next Next ' Change the layer of all of the segments. Call drawView.Parent.ChangeLayer(objColl, newLayer) End If On Error Goto 0 Else ' It's an assembly so process its contents. Call ProcessOccurrences(drawView, occ.SubOccurrences) End If Next End Sub
