iLogic Mating a Component to Assembly Workplane

[felix.cortes5K3Y2]

Hey forum,

I am trying to constrain a part to an assembly relative to a work plane on the assembly using the API but I cannot manage to do it. I need to mate a part with a plane to an assembly plane. I know there is a sample on the programming/API section but that's to mate to another part, which is not what I am trying to do

Here's what I have written so far:

Dim oAsm As AssemblyDocument = ThisApplication.ActiveDocumento
Dim oAsmComp As AssemblyComponentDefinition = oAsm.ComponentDefinition
Dim oOcc As ComponentOccurrence = oAsmComp.Occurrences.Item(1)
Dim oPC As PartComponentDefinition = oOcc.Definition

Dim oWP As WorkPlane = oPC.WorkPlanes.Item(3)
Dim oWPProxy As WorkPlaneProxy
	oOcc.CreateGeometryProxy(oWP, oWPProxy)
	
Dim oAsmWP As WorkPlane
'''???? confused here
''' I think i need to make a proxy for this oAsmWP
''' Just not sure since CreateGeometryProxy is a class from oOcc

oAsmComp.Constraints.AddFlushConstraint(oWPProxy, oAsmWP, "")
	

Thanks!

Felix

First of all, You dont need to create a proxy if you are using planes or any work entities from assembly itself, the proxy is required only if you are using something with occurrences.

Try this rule and see if this helps.

Dim oAsm As AssemblyDocument = ThisApplication.ActiveDocument
Dim oAsmComp As AssemblyComponentDefinition = oAsm.ComponentDefinition
Dim oOcc As ComponentOccurrence = oAsmComp.Occurrences.Item(1)
Dim oDC As PartDocument = oOcc.Definition.Document
Dim oPC As PartComponentDefinition = oDC.ComponentDefinition

Dim oWP As WorkPlane = oPC.WorkPlanes.Item(3)
Dim oWPProxy As WorkPlaneProxy
	oOcc.CreateGeometryProxy(oWP, oWPProxy)
	
Dim oAsmWP As WorkPlane = oAsmComp.WorkPlanes.Item(3) ' You have to define the workplane with which you want to constrain.
oAsmComp.Constraints.AddFlushConstraint(oAsmWP,oWPProxy,"0")
