API_Component3D component; long j, nVertices, nEdges, nPolygons; GSErrCode err; BNZeroMemory (&component, sizeof (component)); component.header.typeID = API_BodyID; component.header.index = ibody; ACAPI_3D_GetComponent (&component); nVertices = component.body.nVert; nEdges = component.body.nEdge; nPolygons = component.body.nPgon;and then I step through all polygons:
for (j = 1; j <= nPolygons; j++) { component.header.typeID = API_PgonID; component.header.index = j; ACAPI_3D_GetComponent(&component); long firstEdge, lastEdge; firstEdge = component.pgon.fpedg; lastEdge = component.pgon.lpedg; // Walk through the edges for (long e = firstEdge; e < lastEdge; e++) { component.header.typeID = API_PedgID; component.header.index = e; ACAPI_3D_GetComponent(&component); // get the edge API_PedgType &edge = ?????????? } }I'm not sure if I'm doing this correct, but I did this in about the same way as stepping through the other elements. So how do I get the list of vertices that is used in one particular polygon?

Oleg is correct regarding the efficiencies of the internal implementation. I also agree with your observation regarding a wrapper class - I have implemented classes for this very purpose. It was more time-consuming to write up-front, but the long-term gain through ease of use has made it worthwhile. Very efficient too. The other main benefit is that we won't suffer so much if the API for this data changes - the differences should be absorbed by the wrapper and not everything based on it.

The situation sounds not so unusual ...
