iLogic: Show Overridden Dimensions

By Dutt Thakar

I have written a handy iLogic utility to check if any dimensions on a drawing are overridden. It scans all of the dimensions on the sheet and checks whether they are overridden or not. If any dimensions are overridden, it will highlight them in red and then show the user that how many dimensions are overridden via message box.

To make it easy to undo the changes to the drawing, I have placed the code in an undo wrapper.

Here is the iLogic code:

'iLogic code By Dutt Thakar 'Originally posted on

oDoc = ThisDoc.Document
oNamer = "Highlight Dimension Overrides"
Dim UNDO As Transaction 
UNDO = ThisApplication.TransactionManager.StartTransaction(oDoc, oNamer)
' Undo Wrapper -------------------------------------------------------------------------------------
Dim oSheet As Sheet = oDoc.ActiveSheet
Dim oColor As Color
'Creating a color based On R, G, B values, here I want To highlight In red so kept it As (255,0,0)
oColor = ThisApplication.TransientObjects.CreateColor(255, 0, 0) 
Dim oDim As DrawingDimension
Dim DimCount As Integer = 0
For Each oDim In oSheet.DrawingDimensions
        If oDim.OverrideModelValue <> oDim.ModelValue Or oDim.HideValue = True Then
            oDim.Text.Color = oColor
			DimCount = DimCount + 1
            oDim.Text.Color = ThisApplication.TransientObjects.CreateColor(0, 0, 0)
        End If	
If DimCount>0
	MessageBox.Show(DimCount & " Dimensions are overridden")
	MessageBox.Show("No Dimensions are overridden")
End If
' Undo Wrapper -------------------------------------------------------------------------------------


This version of the code was briefly tested in Inventor 2021.

As always, please test all iLogic code extensively on non-production files. Do not use any code in a production environment until YOU have thoroughly tested it and have verified that it works as expected. Always back up any data before running any experimental code. You are ultimately responsible for any iLogic code that you run, so make sure you test it thoroughly!
