anyway.. i got it now...
but can anyone tell me how to change the button event for custom toolbars...

coz in addins we are not specifying which event to consider... by default its taking button.execute as click event

Hello Nathan,

can you please paste code.. I need help in with minimum distance logic.

Is there anyway that we can get min distance in X,Y and Z directions??

Cheers.

# Re: Minimum distance

Create two workpoints in your part "P1" and "P2".

Then the distance between these points can be calculated using MinimumDistance method.

Try this iLogic rule:

D = Measure.MinimumDistance("P1", "P2")

MsgBox(D)

In assembly you may use this method to get the minimal distance between two occurrences.

See Inventor API Help for MeasureTools object description.

# Re: Minimum distance

Creation of pointts will disturb the geometry and structure of the modeled part.

I am looking to get minimum distance from face to workpoint.

Much appriciated for solution.

Thank you.

# Re: Minimum distance

In my previous post I used workpoints only as one possible variant of measured objects.

MeasureTools.GetMinimumDistance method works with many entity types:

Part Face, Edge, Vertex, work features, 2d and 3d sketch entities Assembly FaceProxy, EdgeProxy, VertexProxy, work features and their proxies, 2d and 3d sketch entities and their proxies, ComponentOccurrences and their proxies Drawing DrawingViewCurve, GeometryIntent, 2d sketch entities.

See MeasureTools object detailed description in Inventor API Help.

You need to get the reference to the desired Face to be able to measure the distance to the workpoint.

Which method do you use?

In the following VBA sample I get this reference from the first element in the active assembly  SelectSet object.

The name of component (BOX) and the name of workpoint (P1) are hardcoded.

Change them to appropriate values.

Important note:  in assembly context SelectSet always returns proxy objects.

```Private Sub MinDistance_1()

Dim oAssyDoc As AssemblyDocument
Set oAssyDoc = ThisApplication.ActiveDocument

Dim oAssyDef As AssemblyComponentDefinition
Set oAssyDef = oAssyDoc.ComponentDefinition

'1) get the reference to the workpoint "P1"
'   in the component "BOX"
Dim oOcc As ComponentOccurrence
Set oOcc = oAssyDef.Occurrences.ItemByName("BOX")

Dim oDef As PartComponentDefinition
Set oDef = oOcc.Definition

Dim oWP As WorkPoint
Set oWP = oDef.WorkPoints.Item("P1")

'create work point proxy object
Dim oWPproxy As WorkPointProxy
Call oOcc.CreateGeometryProxy(oWP, oWPproxy)

'2) get the reference to the selected face

Dim oSSet As SelectSet
Set oSSet = oAssyDoc.SelectSet

If oSSet.Count = 0 Then
MsgBox "Select some face"
Exit Sub
End If

Dim oObj As Object
Set oObj = oSSet.Item(1)

If Not (TypeOf oObj Is FaceProxy) Then
MsgBox "Select some face"
Exit Sub
End If

Dim oFaceProxy As FaceProxy
Set oFaceProxy = oObj

'3) Measurements
Dim oMeasureTools As MeasureTools
Set oMeasureTools = ThisApplication.MeasureTools

Dim D As Double ' distance (cm)
D = oMeasureTools.GetMinimumDistance(oFaceProxy, oWPproxy)

MsgBox ("D, cm = " & FormatNumber(D, 3))

End Sub 'MinDistance_1```

# Re: Minimum distance

Just getting into iLogic these days, and I thought it would be a great way for me to update Tooling ball tags with the XYZ coordinate info. I used to have a macro (well, still do), but I figure I could eliminate it completely if I could do the same in iLogic. However, I seem to have run into a snag. Using iLogic's MinimumDistance function, I get the numbers I want, EXCEPT they do not specify if they are positive or negative distances (they are all positive), but the coordinates I put on my tooling ball labels must reflect their actual position in space. So does anyone know how I can find if these numbers should be positive or negative?

Here is what I am using so far:for my rule:

```Parameter("TBLABEL #1 NH:1", "XDIST") = Measure.MinimumDistance("YZ Plane", "TOOLING_BALL_1")
Parameter("TBLABEL #1 NH:1", "YDIST") = Measure.MinimumDistance("XZ Plane", "TOOLING_BALL_1")
Parameter("TBLABEL #1 NH:1", "ZDIST") = Measure.MinimumDistance("XY Plane", "TOOLING_BALL_1")```

In the case of my test environment, all the numbers should be negative, but that will vary.

# Re: Minimum distance

OK, I found another thread that helped me get what I am looking for, although I'm probably cheating by just mulitplying the XYZ values by 10 to get them into millimeters!

Here is what I got now:

```Dim oDoc As Document
oDoc = ThisApplication.ActiveDocument
Dim oWorkPoint As WorkPoint
'set workpoint to TOOLING_BALL_1

oWorkPoint = oDoc.ComponentDefinition.WorkPoints.Item("TOOLING_BALL_1")
Parameter("TBLABEL #1 NH:1", "XDIST")=oWorkPoint.Point.X * 10.0
Parameter("TBLABEL #1 NH:1", "YDIST")=oWorkPoint.Point.Y * 10.0
Parameter("TBLABEL #1 NH:1", "ZDIST")=oWorkPoint.Point.Z * 10.0
Parameter("TBLABEL #1 NH:1", "LABEL") = "TOOLBALL"
Parameter("TBLABEL #1 NH:1", "LABEL_NUM")="1"

oWorkPoint = oDoc.ComponentDefinition.WorkPoints.Item("TOOLING_BALL_2")
Parameter("TBLABEL #2 NH:1", "XDIST")=oWorkPoint.Point.X * 10.0
Parameter("TBLABEL #2 NH:1", "YDIST")=oWorkPoint.Point.Y * 10.0
Parameter("TBLABEL #2 NH:1", "ZDIST")=oWorkPoint.Point.Z * 10.0
Parameter("TBLABEL #2 NH:1", "LABEL") = "TOOLBALL"
Parameter("TBLABEL #2 NH:1", "LABEL_NUM")="2"

oWorkPoint = oDoc.ComponentDefinition.WorkPoints.Item("TOOLING_BALL_3")
Parameter("TBLABEL #3 NH:1", "XDIST")=oWorkPoint.Point.X * 10.0
Parameter("TBLABEL #3 NH:1", "YDIST")=oWorkPoint.Point.Y * 10.0
Parameter("TBLABEL #3 NH:1", "ZDIST")=oWorkPoint.Point.Z * 10.0
Parameter("TBLABEL #3 NH:1", "LABEL") = "TOOLBALL"
Parameter("TBLABEL #3 NH:1", "LABEL_NUM")="3"```
