Thanks pennpiper, though you did not provide much useful information.
We are engineering group for fabrication. We and our fabrication group do not have PDS or other software that can read PDS model. All we have here is AUTOCAD.
Though this job effort is small , I would prefer spending $35000 to buy spoolgen instead of manually drawing isodrawings in autocad.The money is big but compared with manufacturing cost , it is nothing. We would not risk any error that comes from manual schetch.
I was a PDS user. ISOGEN is enough for us from my experience. WHat I want to know before placing order is whether ISOGEN can do the same without PDS environment.
While I asked the same question to ALIAS sales, they provide paradox answers. And they are persuading me to buy spoolgen.
Thanks again.
