I read your previous note about the image lab – congratulations! I
know all too well about technologically illiterate management <g>.
But you're not using AutoCAD? I trust you must have some CAD package
that reads/writes DXF. The biggest advantage for AutoCAD in the
architectural community is its overwhelming use – from consultants to
clients to vendors. Not having it on hand can cost a firm projects –
and it is a good modelor for simple shapes that need to be very
accurate (e.g. architecture!).
For an architect, the Shaper and Lofter are most powerful when they
use DXF shapes and paths. A Lofter DXF path insures that the mesh
will allign with the rest of your DXF-imported mesh perfectly. The
quick ability to loft gives many chances to experiment. For the
model-mesh itself I can only speak of AutoCAD for DXF export. You no
doubt have heard of Face Normal nightmares – don't worry, once you
know the nuances you will rarely need to flip normals in 3DS.
VistaPro – fascinating program, but its for terrain modeling/imaging
and not for traditional model building. It creates images or, if you
wish, VERY large DXF files.
Aliging entities in the 3DE – yeah, this is tough. Remember that the
Align command is aligning to the viewport's construction plane – it
can be useful but I would hardly call it an accurate tool. Vertex
snap – it's only availbale when you really don't need it <g>. If you
need to make perfect alignments I'm afraid you are forced to zoom to
the "invalid region" and make sure the vertices align (unless yu can
weld them and just increase your weld threshold). A trick for
centering objects on one another is to copy tracks in the keyframer.
All in all, your best bet at making highly accurate models is to do
it elsewhere (AutoCAD) and bring the model in. The models' origins
match and you will be able to junp between the two programs without
alignment problems fro as long as your project exists, changes, and
evolves.
Hope that helped a little,
