Dear All,

I would like to read several solids in a .obj file to Polyhedron_3 data
structure. 

Question 1: Can I use one Polyhedron_3 to record all these solids? or for
each solid, I should define its own Polyhedron_3 object?

Question 2: How to use ABSOLUTE_INDEXING mode in the incremental_builder? I
read the manual but still a little confused: "...the incremental builder
uses absolute indexing and the vertices of the old polyhedral surface can be
used in new facets." Does that mean I can use begin_surface() to start a new
surface just after the last call of end_surface()? Something like:
-------------------------------------------------------
Builder pB(hds, true);
//1
pB.begin_surface()
...
pB.end_surface()
//2
pB.begin_surface()
...
pB.end_surface()
--------------------------------------------------------
It seems the new surface overwrite the old one, isn't it?

Any ideas? Thanks in advance.

John
