How to create surfaceBody from list of faces and read volume of this surfaceBody

[dariuszm]

Hello,

I would like to read volume of collection of faces. How to create surfaceBody from list of faces and read volume of this surfaceBody?

Im not exactly sure how you want to select the surfaces so this rule will select them all.

Dim doc As PartDocument = ThisDoc.Document
Dim features As PartFeatures = doc.ComponentDefinition.Features

Dim patchFeatures = features.BoundaryPatchFeatures

Dim surfaces As ObjectCollection = ThisApplication.TransientObjects.CreateObjectCollection

For Each item As WorkSurface In doc.ComponentDefinition.WorkSurfaces
    surfaces.Add(item)
Next

Dim oKnitFeature As KnitFeature = features.KnitFeatures.Add(surfaces)

Dim volume = oKnitFeature.SurfaceBodies.Item(1).Volume(0.1)
MsgBox(volume & " cm^3")

Thank you for this. My intention is to collect information about Weld Bead and get all faces of this bead. After this I would like to build transient solid body (same as this bead model) and get a Volume of this transient solid body (or surface body).

Can you help me with this? Do you need any sample file with example weld beads?

If you really want the "transient solid body" this is possible but I expect that you are most interested in the volume. This information can be extracted much easier like this:

Dim doc As AssemblyDocument = ThisDoc.Document
Dim curent As ComponentOccurrence = Nothing
Dim totalVolume = 0.0
Do
    curent = ThisApplication.CommandManager.Pick(
        SelectionFilterEnum.kAssemblyOccurrenceFilter,
        "Select weldbeats (Press esc when all beats are selected.")
    If (curent IsNot Nothing) Then
        Dim beadVolume = curent.SurfaceBodies.Item(1).Volume(0.1)
		Logger.Info(String.Format("{0}: {1}cm^3", curent._DisplayName ,beadVolume))
        totalVolume = totalVolume + beadVolume
    End If

Loop Until curent Is Nothing


Logger.Info(String.Format("Total: {0}cm^3", totalVolume))

Hi, I would like to build my own surface body, because in modele there can be more than one weld bead, but unfortunately Autodesk do all welds in assembly as single solid/surface body. I want to have information about each weld bead volume in assembly. I can get faces from weld bead and base on this info I will build my own surface body (and read volume).
