Mixing COM and .NET

[GTVic]

I am writing a program that creates the following:

1. Point Styles (.NET)
2. Point Descriptions Keys (COM)
3. Marker Style for Survey Figure (COM)
4. Survey Figure Style (COM)
5. Survey Figure Prefix Database (COM)

If you are in the midst of a Transaction block to create a point style, is there any issue with using the COM interface to also create a Marker style? Or is it better to use the COM objects outside of the Transaction.

There seems to be a lot of stuff here that can only be done with COM, is that just work in progress with Autodesk?

For a Survey Figure Style there seems to be no way to set the following in code:

1. Beginning Vertex Marker > Marker Style (Profile mode)
2. Internal Vertex Markers > Marker Style (Profile mode)
3. Ending Vertex Marker > Marker Style (Profile mode)
4. Crossing Marker > Marker Style (Section mode)

You can read these values (e.g. FigureStyle.MidpointMarkersDisplayStyleProfile) but those properties are read-only.

I just want to make sure my assumptions about what you can do in COM vs. .NET are correct.

Thanks

I have not personally ran into a problem running a COM create style in the middle of a transaction. I do choose to create a completely different project and keep COM separate from managed .Net but that is just personal housekeeping.

As regards the marker styles, the SurveyFigureStyle object only provides an ObjectId to the marker style. However, ALL are available.

Profile > Beginning Vertex Marker > Marker Style  = BeginningVertexMarkerStyleId

Profile > Internal Vertex Markers > Marker Style = InternalVertexMarkerStyleId 

Profile > Ending Vertex Marker > Marker Style = EndingVertexMarkerStyleId

Profile > Crossing Marker > Marker Style = CrossingMarkerStyleId

The MidpointMarkersDisplayStyleProfile is for the display settings of the different sub-components. Is this what you are looking for?

See image below, this is what I was looking for. I corrected a one thing since I first posted this.

I mispoke referring to MidPointMarkersDisplayProfile, that is related to display settings as you said and I already have those set up properly, I think. The problem is the names don't match (VertexMarkersDisplayStyleProfile for Beginning Vertex Marker, MidpointMarkersDisplayStyleProfile for Internal Vertex Marker and EndpointMarkersDisplayStyleProfile for Ending Vertex Marker).

With oFigureStyle
    With .FigureLinesDisplayStyleProfile
        .Visible = True
        .Layer = sKeyAtts(3)
        .Color = 256
        .Linetype = "ByLayer"
        .LinetypeScale = 1.0
        .Lineweight = 256
        .PlotStyle = "ByLayer"
    End With
    With .VertexMarkersDisplayStyleProfile
        .Visible = True
        .Layer = sKeyAtts(3)
        .Color = 256
        .Linetype = "ByLayer"
        .LinetypeScale = 1.0
        .Lineweight = 256
        .PlotStyle = "ByLayer"
    End With
    With .MidpointMarkersDisplayStyleProfile
        .Visible = True
        .Layer = sKeyAtts(3)
        .Color = 256
        .Linetype = "ByLayer"
        .LinetypeScale = 1.0
        .Lineweight = 256
        .PlotStyle = "ByLayer"
    End With
    With .EndpointMarkersDisplayStyleProfile
        .Visible = True
        .Layer = sKeyAtts(3)
        .Color = 256
        .Linetype = "ByLayer"
        .LinetypeScale = 1.0
        .Lineweight = 256
        .PlotStyle = "ByLayer"
    End With
End With

I was not able to find AeccSurveyFigureStyle.InternalVertexMarkerStyleId. Where did you find that property?

Thanks

I did not follow Rule #1 - Always read in full OP comments.

What I posted is all from the .Net API and NOT com. Sorry about that. I just don't deal with COM anymore unless I absolutely have to so can't help you much on the COM side.

Ok, I was unable to find SurveyFigureStyle at all under .NET, can you give me a head start on where to find those properties in the maze? 🙂

SURE! Assuming that you have referenced that AeccDbMgd and AecBaseMgd dll, the Survey figure style object is located at:

Autodesk.Civil.Survey.DatabaseServices.Styles.SurveyFigureStyle

Don't forget about object browser. Oftentimes when I am looking for something, I will do a quick search there.

Thanks, I was searching in the .NET API reference CHM file but got nothing. Maybe I'll be able to find the other items in .NET as well.

...deleted..... Ok, maybe not....back to looking.

After searching through the object browser I can create #3/#4 with .NET also.

1. Point Styles (.NET)
2. Point Description Key Set (Point Description Keys) (COM)
3. Marker Style for Survey Figure (.NET)
4. Survey Figure Style (.NET)
5. Survey Figure Prefix Database (COM)

So I guess I'm stuck with COM for #2 and #5
