The component data that you can read in Navisworks or Design reviewer after exporting is good for the client to have, it will help them align our model to the P&IDs.
We just do not want the client to be able to drop ISOs after we hand over the model for review purposes only. We often have repeat work from the same project/client and if we handed over everything they could go out for a bid with our model.
I will encourage clients to get Navisworks if they do not have Design Reviewer and SaveAs > CWEXPLODE as a last resort. Thanks.
