ilogic Can't find coordinates of geometryintent

Anonymous · ‎10-07-2019

Hi all,

I am trying to create i kind of autoballoon function.

I found that it is pretty hard to move the leaderpoitn that has the arrow on it.

but now i want to use the location where the balloon leader is starting to relocate the balloons.

The startpoint of the leader is created using the 'creategeometryintent' function.

for this function i use a curve as input, and the output is a point2D.

now the problem is that when i want to read the coordinates point, but when i put this in a messagebox i get an error.

also when i create a paramter as a double and write the coordinate to this, it wont work.

can someone explain why i cannot read the coordinates of this point?

this code can be run from any drawing with at least 4 views in it, so feel free to try.

Dim oDrawing As DrawingDocument = ThisApplication.ActiveDocument	
Dim oSheet As Sheet = oDrawing.ActiveSheet
Dim oView As DrawingView = oSheet.DrawingViews.Item(4)
Dim oReferDoc As AssemblyDocument = oView.ReferencedDocumentDescriptor.ReferencedDocument
Dim oAssyDef As AssemblyComponentDefinition = oReferDoc.ComponentDefinition
Dim Occ As ComponentOccurrence
Dim oCurve As DrawingCurve
	For Each Occ In oAssyDef.Occurrences

Okay, So for intereseted people i have an update.

apparently the geometryintent is empty.

when checking the code in VBA the it is empty trhough the entire code.

so how the balloon can connect to a line is very strange.

Also i found out that a balloon doesnt strat at the arrow, but at the balloon(circle),

This is something different then when you want to place them manually.

I Also tried moving the rootnode of the balloon using a prefixed point2D.

I don't get any errors when doing this, but it also doesn't move anything.

How is it not possible to modify anything to a balloon when you have already placed them.

so i have two options that both don't work (in red):

1: read the point where the balloon is connected to the part, and then give it a leaderpoint accordingly

2: read the last leadernode of the balloon and then move the rootnode accordingly

is there any option to do this in code or is this so deep into the program that it is not possible?

Kind regards,

hi in your code where you try to get the GeometryIntent, i dont see a property/eNum to tell inventor wich point on the curve you want to use. therefor you need to use the enum: "PointIntentEnum". Pay attension that not all types of curves have the same points. for example a line does not have a centerpoint (that is for circular curves) but does have a mid point.

you could try to replace the line:

Dim oGeometryIntent As GeometryIntent = oSheet.CreateGeometryIntent(oCurve)

with:

    Dim geoType = oCurve.Segments.Item(1).GeometryType
    Dim oGeometryIntent As GeometryIntent
    If (geoType = Curve2dTypeEnum.kLineSegmentCurve2d) Then
        oGeometryIntent = sheet.CreateGeometryIntent(oCurve, PointIntentEnum.kStartPointIntent)
    ElseIf (geoType = Curve2dTypeEnum.kCircleCurve2d) Then
        oGeometryIntent = sheet.CreateGeometryIntent(oCurve, PointIntentEnum.kCircularLeftPointIntent)
    End If

for your situation you might want to change the PointIntentEnum.?????? to something else. See help for all options.

(disclamer: i did not have time to try this out but expect that it would work.)

Thanks for the answer!

I didn't know i could specify a certain type of point to the geometryintent.

I also found out how to move the balloon around the sheet.

It is not possible moving the balloon with a X and Y coordinate seperate, but you have to assign a point2D to the position, something like this:

Dim Point As Point2d = oTG.CreatePoint2d(6, 10)
oBalloon.Leader.AllNodes.Item(1).Position = Point

i will post my code here if i got it working functionally

kind regards,

so for everyone interested in an autoballoon function. the code i have so far works.

Only thing to modify is that the leaders can intersect each other, so that is something to improve.

the code is created with the intention to only balloon the iso view that is view 4.
