RFShell.AddFaces (Available After RapidForm2004 PlusPack1)

Description

Adds new faces which consists of three ordered vertices to the shell, and retrieves RFEntityID values indicating entity ID of the new faces.

Syntax

Function RFShell.AddFaces(numFace As Long, pVertexID1s As RFEntityID, pVertexID2s As RFEntityID, pVertexID3s As RFEntityID, bCheckManifold As Boolean, pFaceIDs As RFEntityID) As RFErrorCode

The AddFaces syntax has these parts:

Part	Description
numFace	[IN] Long Required. The number of faces to be added.
pVertexID1s	[IN] RFEntityID Required. EntityIDs of the first vertices.
pVertexID2s	[IN] RFEntityID Required. EntityIDs of the second vertices.
pVertexID3s	[IN] RFEntityID Required. EntityIDs of the third vertices.
bCheckManifold	[IN] Boolean Required. It should be set TRUE to prevent a non-manifold edge from being generated.
pFaceIDs	[OUT] RFEntityID Required. EntityIDs of the new faces.

Remarks

pVertexID1s(i), pVertexID2s(i), and pVertexID3s(i) should be properly ordered to satisfy right-hand rule for obtaining the face normal.
A set of three ordered vertices {a,b,c} is identical to {b,c,a} and {c,a,b} in terms of normal direction. Face object provides RFFace.ReverseNormal method to switch the sense of face normal direction.
With bCheckManifold = TRUE option, if the specified face forms a non-manifold edge, a new face is not added and retrieved RFEntityID is NULL(0).
