[API] Traverse an Assembly and Print off minRange Location for Each Part

[lemensk]

When you are tranversing through an assembly, how can you create a list with the part name and its GLOBAL minRange value?  How would you use proxies to accompolish this?

Thank you,

Hi,

If you access the range in the assembly context, you can use ComponentOccurrence.RangeBox without proxy because this has been transformed in the assembly context.

[lemensk]

Mr. Liang,

Isn't your comment a 'half' truth?  Before I posted the question, I had operating code that extracted Rangebox.  However, my model had sub-assemblies and one particular sub-assembly was rotated 90degrees to the Global Assembly axis; so the 'x' minRange was the actually the Global 'z' value.

I beleive I can get around this by utilizing a proxy, but I was hoping for a simplified/error-proof technique.

Thank you,

Have you tried something like this? I've used this method for similar situations.

ComponentOccurrence myOccurance;
foreach(SurfaceBody body in myOccurance.SurfaceBodies)
{
   if (body is SurfaceBodyProxy)
   {
      SurfaceBodyProxy bodyProxy = (SurfaceBodyProxy)body;
      SurfaceBody NativeBody = bodyProxy.NativeObject;
      Box bodyRange = NativeBody.RangeBox;
      //whatever logic you need with the range box
   }
}

Hi Kenny,

The RangeBox is a rectangular box that is guaranteed to enclose this object. I tested with the attached part, sub-**** and top-****, placing the occurrences with different rotations. The RangeBox looks well to me. Their locations are in the context of the top assembly The code is as below. 

Or I misunderstood your question?

Sub getPartParam()

 Dim oAssDoc As AssemblyDocument
 Set oAssDoc = ThisApplication.ActiveDocument
 
  Dim localAsset As Asset
  Set localAsset = oAssDoc.Assets.Item("Clear")

 Dim oCompDef As ComponentDefinition
 Set oCompDef = oAssDoc.ComponentDefinition
        
 Dim oTransientBRep As TransientBRep
 Set oTransientBRep = ThisApplication.TransientBRep

On Error Resume Next
Dim oClientGraphics As ClientGraphics
Set oClientGraphics = oCompDef.ClientGraphicsCollection.Item("Sample3DGraphicsID")
If Err.Number = 0 Then
    On Error GoTo 0
    oClientGraphics.Delete
  
    ThisApplication.ActiveView.Update
    
      Err.Clear
    Exit Sub
    
 End If
   
  Set oClientGraphics = oCompDef.ClientGraphicsCollection.Add("Sample3DGraphicsID")
  
  Dim oSurfacesNode As GraphicsNode
  Set oSurfacesNode = oClientGraphics.AddNode(1)
  
  oSurfacesNode.Appearance = localAsset
 
    Dim oOcc As ComponentOccurrence
    For Each oOcc In oAssDoc.ComponentDefinition.Occurrences
        Dim oRB As Box
        Set oRB = oOcc.RangeBox
        
         Dim oBody As SurfaceBody
         Set oBody = oTransientBRep.CreateSolidBlock(oRB.Copy())
        
      ' Create client graphics based on the transient body
        Dim oSurfaceGraphics As SurfaceGraphics
        Set oSurfaceGraphics = oSurfacesNode.AddSurfaceGraphics(oBody)
      
Next

oSurfacesNode.Appearance = localAsset
ThisApplication.ActiveView.Update
End Sub

I am trying to extract part locations.  Here is my model:

(IMAGE1)

You will notice that I have (6) posts, both comprised of Angle 1:1 and Angle 1:2.  Here is the result I get when I print off the parts MinRange and MaxRange Properties:

(IMAGE2)

As you will notice, they are all identical.  I understand your code in the context that the Min and MaxRange values provided by Occurrences of an Assembly all have the same datum, but when I try to access parts in a sub-assembly (i.e., a face of one of your cube) I only get the min/max values that pertain to it locally (i.e. x,y,z values pertaining to the cube origin, not the assembly origin).  Granted, I have created a coorolation between locaiton of a subassembly to the main assembly and add the difference between the two to the min/max range values, but this all falls apart when the subassembly itself has a different axis orientation then the main assembly.

I was hoping to use proxies, but I'm having trouble  at generating a vector between the global origin and a parts min/max range values.

-thanks, Ken

Hi Ken,

You should try to modify Xiao's code to make it work for your assembly and if it does not work as you need it then show us how you modified it.

I think you are retrieving the data in context of the subassembly you activated - i.e. "Support 2:1" -, but what you seem to want is the locaion in context of the topmost assembly.

Using proxies is not more complicated than getting the information in a different context and then doing transformations on them: http://adndevblog.typepad.com/manufacturing/2013/07/occurrences-contexts-definitions-proxies.html

I hope this helps.

What it is supposed to do it print off (2) points for each part, the beginging of a member and the end of the member.

What would make this REALLY easy is if there is code out there to 'destory' and assembly and 'float' all the parts to the surface (i.e. one level).  Heck, I wouldn't even mind if it created a 10 MG file and took 2 days for run time

[adam.nagy]

Hi,

I think that Xiao's code is pretty close to what you want. I think you just want to go down to the leaf occuurrences, the actual parts.

You just need to modify the following part in the getPartParam function from this:
For Each oOcc In oAssDoc.ComponentDefinition.Occurrences

to this:

For Each oOcc In oAssDoc.ComponentDefinition.Occurrences.AllLeafOccurrences

Note: you also need to add the "Clear" appearance style to the document in the "Appearance Browser" palette before running the code.

Cheers,

Below is the answer to my question.  Surprised how hard it was to get such simple code:

'CODE START ---------------------------------

Sub printParts()
   Dim inventDoc As Inventor.AssemblyDocument
   Dim deltaX, deltaY, deltaZ, avgX, avgY, avgZ, minX, minY, minZ, maxX, maxY, maxZ As Double
   Dim fileName, strg As String

   Dim partOccur As Inventor.ComponentOccurrence

   Set inventDoc = ThisApplication.ActiveDocument
   fileName = inventDoc.DisplayName

   For Each partOccur In inventDoc.ComponentDefinition.Occurrences.AllLeafOccurrences   'For each part included in the assembly
       strg = partOccur.Name & ";" & partOccur.RangeBox.minPoint.X & ";" & partOccur.RangeBox.minPoint.Y & _

                 ";" & partOccur.RangeBox.minPoint.Z

      Open "C:\Temp\" & fileName & ".txt" For Append As #1 'Open txt file and Append
      Print #1, strg                                                                         'Print String
      Close #1                                                                                'Close txt file
   Next
   
End Sub

'CODE STOP ---------------------------------

[lemensk]

How does "Appearance Browser" compromise code?

[adam.nagy]

What do you mean exactly?

[lemensk]

Quote: "Note: you also need to add the "Clear" appearance style to the document in the "Appearance Browser" palette before running the code."

I don't access the Appearance Brower palette at all; would I NEED to do something with the Appearance Brower or fear unreliable/contaminated data from Leaf Occurrences?
