Function CreateBodyFromSurfaces() As System.Boolean

Dim instance As IBody2
Dim value As System.Boolean
 
value = instance.CreateBodyFromSurfaces()

System.bool CreateBodyFromSurfaces()

System.bool CreateBodyFromSurfaces(); 

Return Value

True if solid body is created

False if:

• solid body is not created
  - or -
• surface body is created

To create a body using trimmed surfaces:

1. Create a new temporary body in a part using IPartDoc::CreateNewBody.
2. Create the trimmed surfaces in the shape of the new body (for example, six square surfaces that intersect at the edges to form a cube).

   • Create a planar surface based on a root point and normal (two, three cell VARIANT arrays) using IBody2::CreatePlanarSurface(RootPoint, Normal).

   • Add a trimming loop to the planar surface using
     ISurface::AddTrimmingLoop2(Numcurves, _  
     Order, _
     Dimen, _
     Periodic, _
     NumKnots, _
     NumCtrlPoints, _
     Knots, _
     CtrlPointDbls, _
     UVRange)

   • Create a trimmed surface on the body based on the trimming loop that was just created. The arguments for Surface::AddTrimmingLoop2 and their values for a square are:
      

     Argument	Description
     NumCurves	Number of curves that make up the loop (4 Long)
     Order	Orders for the spline curves ({2, 2, 2, 2} Array of Longs)
     Dimen	Dimension of the control points for the spline curves ({2, 2, 2, 2} Array of Longs)
     Periodic	Periodicity of the spline curves ({0, 0, 0, 0} Array of Longs)
     NumKnots	Number of Knots of the spline curves ({4, 4, 4, 4} Array of Longs)
     NumCtrlPoints	Number of Control points for the spline curves ({2, 2, 2, 2} Array of Longs)
     Knots	Describes the locations of the knots ({0, 0, 1, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0, 0, 1, 1} Array of Doubles. Each knot represented by four numbers 0, 0, 1, 1)
     CtrlPointDbls	Control points for the TrimmingLoop ({0, 0, 1, 0, 1, 0, 1, 1, 1, 1, 0, 1, 0, 1, 0, 0} Array of Doubles. Describes the corners of the square)
     UVRange	Min and max for the U and V values ({0, 1, 0, 1} Array of Doubles)

3. Sew the surfaces together into a new body using this method.
