Assign component occurrence to variable

Anonymous — Sun, 16 Nov 2014 09:51:21 GMT

Hi,

I'm trying with vb.net to assign a virtual component to a variable. The following code creates the virtual component "Assembly" if it doesn't exists :

Dim _asmCompDef As AssemblyComponentDefinition
_asmCompDef = _doc.ComponentDefinition

Dim identity As Matrix
identity = _invApp.TransientGeometry.CreateMatrix

Dim occs As ComponentOccurrence
occs = _asmCompDef.Occurrences.AddVirtual("Assembly", identity)

I don't know how to assign this virtual component to a variable.

This code creates an error :

Dim existingOcc As ComponentOccurrence
existingOcc = _asmCompDef.Occurrences.Item("Assembly")

Hi,

The best thing is always to test things in VBA. There you would have got a Type mismatch error that could have pointed you in the right direction.

Item() expects a Long input parameter. You could use ItemByName instead, but that as well will also need the occurrence counter too, i.e. "Assembly:1"

I hope this helps,
