Extend and Trim in Inventor 2014

[Anonymous]

I have two Surface bodies apart from each other (but, sort of, perpendicular, L like). How can I extend, trim and stitch them to form a single surface body.

In Inventor 2014 you can use the Combine(Part->3D Model->Modify->Combine) command to merge two solids into a single solid.

I am looking for APIs for surfaces.

As Rocky mentioned, you can use a CombineFeature to merge solid bodies:

Sub CombineBodies()

        Dim doc As PartDocument
        Set doc = ThisApplication.ActiveDocument

        Dim def As PartComponentDefinition
        Set def = doc.ComponentDefinition

        Dim baseBody As SurfaceBody
        Set baseBody = def.SurfaceBodies(1)

        Dim toolBodies As ObjectCollection
        Set toolBodies = _
            ThisApplication.TransientObjects.CreateObjectCollection

        toolBodies.Add def.SurfaceBodies(2)

        Dim combineFeature As combineFeature
        Set combineFeature = def.features.CombineFeatures.Add( _
            baseBody, toolBodies, kCutOperation, True)

End Sub

For surfaces, you use a knit (stitch) feature. See "KnitFeatures.Add Method" in the help files.

ExtendFeature and TrimFeature creation is not exposed in the API.

I hope that helps,

Philippe.

In case of surfaces, if they are near to each other at boundaries, then it seems to work. But if one surface is perpendicular to the orher, in the middle, like letter "T", then stitching does not happen. It should trim at the intersection, create edge and then stitch. Any solution to get "T" like stitching of surfaces?
