Re: 3-D Modeling of structures in a Process Plant

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Here in our company we use also PDMS for modeling the plant. At the
beginning we also tried to use PDMS for our structural drawings preparation,
but we couldn't reach to a practical method which reduce our efforts. Only
we used the software for shop fabrication drawings preparation. We defined
our connection specification for the software and it automatically put the
connection into its place. It helped us greatly. So if you don't have a
professional software for shop fabrication drawings I suggest to try PDMS.
