Determine if Drawing Dimension is Broken

Maxim-CADman77 — Sat, 18 Apr 2020 16:36:25 GMT

I'd like to know the way to determine if particular Drawing Dimension is Broken.

I mean those dimensions crossing View-Break sign like this:

For now I don't even see any simple way to get the name of a DrawingView the Dimension belongs to.

Inventor itself can determine it (judging by the display option in dimension style settings):

Hi @Maxim-CADman77 ,

You should be able to identify such dimension lines by querying the (Get/Set) ShowBreakSymbol() boolean on the DimensionStyle Object as documented here.

Let me know in case of any further questions.

Edit: I might have misinterpreted the question. You don't necessarily need to know which view the dimensions belong to but rather the position of their GeometryIntents in relation to the Start and End Point of the Break Operation in addition to their orientation. That way you should be able to determine whether ShowBreakSymbol() should be true or not.

Does that approach make sense and is easy enough to implement?

I believe this is related only to dimension style but not particular dimensionns.

Hi @Maxim-CADman77 ,

Ah I see what you mean.

Within the Dimension you can only query and change the property via the dimensions' "Style" and changes would be made to the style itself.

If you do have the requirement to set the BreakSymbol per Dimension, I believe it would be best to log it on the IdeaStation.

I'd rather prefer some (even tricky) workaround within next several days than ideal solution several years later.

@Maxim-CADman77,

Try below VBA code to identify broken dimension in drawing.

Sub Select_Broken_Dimension() Dim oDoc As DrawingDocument Set oDoc = ThisApplication.ActiveDocument Dim oSheet As Sheet Set oSheet = oDoc.ActiveSheet Dim oDimension As DrawingDimension For Each oDimension In oSheet.DrawingDimensions Dim d As Double d = distance(oDimension.DimensionLine.StartPoint.Y, oDimension.DimensionLine.StartPoint.X, oDimension.DimensionLine.EndPoint.Y, oDimension.DimensionLine.EndPoint.X) d = d / 10 If d <> oDimension.ModelValue Then Call oDoc.SelectSet.Select(oDimension) End If Next End Sub Function distance(ya As Double, xa As Double, yb As Double, xB As Double) distance = Sqr((ya - yb) ^ 2 + (xa - xB) ^ 2) End Function

Please feel free to contact if there are any queries.

Thanks and regards,

This is good idea!

But still needs adding some analysis of the Drawing View.

I mean it doesn't take to consideration DrawingView Scale value (works as expected only for dimensions belong to 1:1 Scaled Views).

PS: I believe it's also worth to compare rounded values, like:

If Round(d,8) <> Round(oDD.ModelValue,8) Then

@Maxim-CADman77,

Please provide non confidential sample drawings (different scale) to test the feasibility.

Thanks and regards,

I believe you don't need another sample.

Just change Drawing View Scale value to something different from "10:1".

Then to keep it working as expected you'll need to change accordingly the hard-coced multiplier in line

 d = d / 10

For Dimension that belongs to 5:1 Scaled View:
d = d/5

For Dimension that belongs to 1:2 Scaled View:

d = d*2

...etc.

I still hope it is possible to get scale multiplier of the parent view for each dimension...

I'm attaching a sample set of model and drwing with several broken dimensions on several views with different scale.

I still hope somebody will help me to make VS (View Scale) variable an accosiative.

My current code is:

Sub Main Dim oIDW As DrawingDocument = ThisApplication.ActiveDocument Dim oSh As Sheet = oIDW.ActiveSheet Dim oDD As DrawingDimension Dim MsgMody As String Dim VS As Double ' View Scale For Each oDD In oSh.DrawingDimensions MsgBody &= oDD.Text.Text ' MsgBody &= oDD.ModelValue VS = 1/2 ' !!!! Dim d As Double = OnIDWdistMM(oDD.DimensionLine.StartPoint.Y, oDD.DimensionLine.StartPoint.X, oDD.DimensionLine.EndPoint.Y, oDD.DimensionLine.EndPoint.X) / VS MsgBody &= " (" & Round(d,3) & ")" ' If Round(d,8) <> Round(10*oDD.ModelValue,8) Then MsgBody &= " - BROKEN !!!" MsgBody &= vbCrLf Next MsgBox(MsgBody,,"Dimensions' Break status:") End Sub Function OnIDWdistMM(ya As Double, xa As Double, yb As Double, xB As Double) OnIDWdistMM = 10 * Sqrt((ya - yb) ^ 2 + (xa - xB) ^ 2) End Function
