Get Solid Body with Sculpt Feature

[ga42bon]

Hello everybody,

I'm trying to convert my SurfaceBody/NonParametricBaseFeature into a solid body. My idea is to use a SculptFeature as this works already manually.

You can see the feature to convert in the screenshot down below.

The code to get this feature into my PartDocument is here:

' Get the source document
Dim oSourceAsmDoc As AssemblyDocument = g_inventorApplication.ActiveDocument

' Get the Interference Body.
Dim oIntBody As SurfaceBody = oCollision.oIntBody

' Copy the face as a transient B-Rep face.
Dim oNewBody As SurfaceBody = g_inventorApplication.TransientBRep.Copy(oIntBody)

' Add the body to the existing gripper jaw document
Dim oTargetPartDoc As PartDocument = g_inventorApplication.Documents.Item(3)

' Create a non-parametric base feature using the face as a transition to get rotated face
Dim oTransitionNPFeature As NonParametricBaseFeature = oTargetPartDoc.ComponentDefinition.Features.NonParametricBaseFeatures.Add(oNewBody)

 I copied an interference body from an assembly document to a part document using an adaption of the following issue: https://forums.autodesk.com/t5/inventor-ilogic-and-vb-net-forum/transformation-of-surfacebody-copy-d...

My idea to use a SculptFeature is based on the following steps done manually ("Formen" is german for Sculpt):

"Formen" is german for Sculpt

The result of Sculpt -> New Body is a solid body

I already tried to write these steps in Visual Basic:

' Creat sculpt surface collection
Dim SurfCol As ObjectCollection = g_inventorApplication.TransientObjects.CreateObjectCollection
        SurfCol.Add(oTransitionNPFeature)

' Create a sculpt feature; convert SurfaceBody to Solid
Dim oSculptFeature As SculptFeature = oDoc.ComponentDefinition.Features.SculptFeatures.Add(SurfCol, PartFeatureOperationEnum.kNewBodyOperation)

The problem is the input of the SculptFeature.Add Method. I couldn't the right solution what to type as an input for this method yet.

I've tried the following:

1. CreateSculptSurface -> Error with input (oNewBody or oTransitionNPFeature)
2. Add -> Error with input (oNewBody or oTransitionNPFeature)
3. First creating a surface collection and use the method Add -> same Error with input

Is there a way to convert this SurfaceBody or NonParametricBaseFeature into a Solid? Preferably with the method SculptFeature.Add?

I would be very happy to receive some help with this issue.

Thank you!

Sebastian

You might want to have a look at this post. There I wrote a rule that creates a solid box using a "NonParametricBaseFeature". Maybe you can use that rule as an example.

Thanks a lot! @JelteDeJong 

With some lines of code in this post I could turn my NonParametricBaseFeature into solid.
