Inventor 2025 different results with same iLogic rule

Curtis_W — Fri, 12 Apr 2024 22:22:27 GMT

Please see the attached video and code sample and note the different results.

The correct result is what 2024 outputs, 2025 seems to be ignoring the line to set the display to wireframe???

Can someone help me understand why the 2 version provide different results when running the same code?

@johnsonshiue or @MjDeck can you confirm that this is not working as expected, or point out why we'd get 2 different results?

We have a customer needing this functionality and we need to find some other solution is this is indeed a bug, but I thought/hoped maybe I was misunderstanding something???

Dim m_Doc = ThisApplication.ActiveEditDocument

oFolder = "C:\Temp\Part Preview\"
Dim oFileName = oFolder & "Thumb Nail Pic.jpg"

Dim m_Camera As Inventor.Camera
m_Camera = ThisApplication.TransientObjects.CreateCamera()

m_Camera = ThisApplication.TransientObjects.CreateCamera()
If m_Doc.DocumentType = DocumentTypeEnum.kPartDocumentObject Then
	m_Camera.SceneObject = DirectCast(m_Doc, PartDocument).ComponentDefinition
Else
	m_Camera.SceneObject = DirectCast(m_Doc, AssemblyDocument).ComponentDefinition
End If

'get current settings
m_Disp3D = ThisApplication.DisplayOptions.Show3DIndicator
m_PrevMode = ThisApplication.DisplayOptions.NewWindowDisplayMode

ThisApplication.DisplayOptions.NewWindowDisplayMode = DisplayModeEnum.kWireframeNoHiddenEdges
ThisApplication.DisplayOptions.Show3DIndicator = False
m_Camera.Perspective = False

m_Camera.ViewOrientationType = Inventor.ViewOrientationTypeEnum.kIsoTopLeftViewOrientation
m_Camera.Perspective = False
m_Camera.ViewOrientationType = Inventor.ViewOrientationTypeEnum.kIsoTopLeftViewOrientation
m_Camera.Fit()
m_Camera.ApplyWithoutTransition()

Try
	m_Camera.SaveAsBitmap(oFileName, 600, 600, ThisApplication.TransientObjects.CreateColor(255, 255, 255))
Catch ex As Exception
	MsgBox(ex.Message)
Finally
	'reset options
	ThisApplication.DisplayOptions.NewWindowDisplayMode = m_PrevMode
End Try

Hi Curtis - so far I haven't been able to get the rule to produce a wireframe image on Inventor 2024.
Which exact version of 2024 are you running? Have you tried it on another machine?
I'm not sure if the Camera is supposed to follow the display settings for new windows. After all, it's not a window. I'm looking into it.
Maybe you could use a View instead of a Camera?

Thanks Mike!

This testing has mostly just been on this one machine, as far as 2025. But I've had others run this routine with 2023 and 2024, with the wireframe results working as expected.

I was running version 2024.2 build 272, but just installed update 3 and I see the same results with 2024.3 build 343. Meaning that I get the wireframe thumbnail as expected with update 3.

I'll rewrite this with View and see what I get, and post back.

Thanks again!

Update: using view rather than camera for the display mode/ wire frame setting did indeed resolve this.

Dim oFileName = "C:\Temp\Thumb Nail Pic.jpg" Dim oView As Inventor.View = ThisApplication.ActiveView Dim oCamera As Inventor.Camera oCamera = oView.Camera Dim oCurrentDisplayMode As DisplayModeEnum = oView.DisplayMode Dim oCurrentViewOrientation As ViewOrientationTypeEnum = oCamera.ViewOrientationType ThisApplication.ScreenUpdating = False ThisApplication.DisplayOptions.Show3DIndicator = False oView.DisplayMode = DisplayModeEnum.kWireframeNoHiddenEdges oCamera.Perspective = False oCamera.ViewOrientationType = Inventor.ViewOrientationTypeEnum.kIsoTopLeftViewOrientation oCamera.Fit() oCamera.ApplyWithoutTransition() Try oCamera.SaveAsBitmap(oFileName, 600, 600, ThisApplication.TransientObjects.CreateColor(255, 255, 255)) Catch ex As Exception MsgBox(ex.Message) Finally oCamera.ViewOrientationType = oCurrentViewOrientation oCamera.ApplyWithoutTransition() ThisApplication.ActiveView.DisplayMode = oCurrentDisplayMode ThisApplication.DisplayOptions.Show3DIndicator = True ThisApplication.ScreenUpdating = True ThisApplication.ActiveView.Update() End Try
