what does the catia forum have to do with it?
are both prg for plant engineering (piping).
pds of the intergraph has long been abandoned in favor of the new sw smartplant3d
pdms is constantly updated
both are very powerful and suitable for "consistent" projects where they fully exploit their potential.
the limit, beyond the cost of setup for a project, is the administration of the same that requires dedicated and specially trained staff.
Thank you for the answer. I am recently enrolled and I am not yet well oriented on the site, in particular to introduce new discussions. but between smartplant3d and pdms which would you recommend?
