Pipe Network Catalog, set default folder

[dherbstr]

Company is migrating 100 users from C3D 2016 to 2017. I'm looking for an automated way to set the Pipe Network Catalog Folder without having to go to each machine. For the new deployments I'll be using lisp to set the support paths, via this method from rkmcswain, but I don't see a support path for the pipe catalog.

A few notes. The company is migrating all support files to a common server for the first time. We have four separate office locations. I've done similar support path setting in AutoCAD for an architecture firm, this is my first time in the Civil Engineering and C3D world. Until now the company has done stand-alone installs with standards copied local (manually).

I'm hoping to avoid having to write a lisp to modify each user's registry. Is there a way to set the folder path via lisp? Without editing the registry? Can I set this once with the deployment, instead of placing it in acad.lsp and loading it every time? Or am I just missing the support path for the pipe network catalog folder?

Thanks in advance.

Just saw this post. This is do-able with lisp, but it does modify the registry.
Since it *is* in the registry, perhaps you can set it with group policy at PC startup time?

I finally conceded to using lisp and writing to the registry, then I just call the lisp from acad.lsp. It's worked for us so far across 100 users and four offices.

I've attached the lisp if anyone is interested. Thanks.
