Inventor iLogic: creating assembly by using imates with iLogic coding

[Anonymous]

Hello,

 I would like to create assembly by using iLogic codification. refer below code I used method to create an assembly - by using iMates constraint.

 The below code is worked well, but whenever I run the rule, assembly components occurred multiple times, which I would like to avoid.

can somebody give me solution to control the component occurrence in the assembly. I want only one time occurrence of each part in assembly.

there are total three parts in assembly.

Also I have attached jpg file for multiple component instance in assembly, while running rule each time with the below iLogic code.

Dim oAsmCompDef As AssemblyComponentDefinition

oMatrix = ThisApplication.TransientGeometry.CreateMatrix
oMatrix.SetTranslation(ThisApplication.TransientGeometry.CreateVector(0,0,0))
' Place the first occurrence.
Dim oOcc1 As ComponentOccurrence
oOcc1 = oAsmCompDef.Occurrences.Add("C:\Data\GMS\OHH BSP iLogic Generator\Volute Casing\1.5x3x10-Case-OHH_E1204500533.ipt", oMatrix)
' Place the second occurrence, but use iMates for its placement. This is' equivalent to "Use iMate" check box on the "Place Component" dialog.
oMatrix.Cell(1, 4) = 1
Dim oOcc2 As ComponentOccurrence
oOccEnumerator = oAsmCompDef.Occurrences.AddUsingiMates("C:\Data\GMS\OHH BSP iLogic Generator\Casing Cover\04-Cover-OHH_E1204501642.ipt", False)
' Since the 'PlaceAllMatching' flag was specified as False, we can be' sure that just one ComponentOccurrence was returned in the enumerator.
Dim oOcc3 As ComponentOccurrence
oOccEnumerator1 = oAsmCompDef.Occurrences.AddUsingiMates("C:\Data\GMS\OHH BSP iLogic Generator\Bearing Housing\3C-OHH-Bearing.ipt", False)


' oOcc1 = oOccEnumerator.Item(1)

Hi,

What inventor version are you using?

Inventor 2019 ilogic contains Managed components, which should help you.

Hi,

You Said:

"The below code is worked well, but whenever I run the rule, assembly components occurred multiple times, which I would like to avoid."

I think you must learn about iMate matching name first.

Example:

in Comp1, have 3 iMate

1. C1XY, matching to C2XY

2. C1XZ, matching to C2XZ

3. C1YZ, matching to C2YZ

so in Comp2, set iMate to:

1. C2XY, matching to C1XY

2. C2XZ, matching to C1XZ

3. C2YZ, matching to C1YZ

now in Comp3, set iMate to? Comp1 or Comp2?

Note: if 1 iMate in error or constrainst was no same type in another component imate, I will throw error, and will place multiple component.
