The MDS application is supplied with a catalogue and specification. The range of bore and components in the catalogue are fixed and should be adequate for all projects. The catalogue supplied in the MDS project and associated ‘/MDS’ specification must not be modified by the administrator or any other user.

This release of the MDS application sees the introduction of a USER DEFINED ancillaries catalogue for various types of pipe support attachments. The USER DEFINED ancillaries catalogue is supplied in the MDU project.

Only certain elements of the MDU catalogue components PTSE & GMSE may be modified. The /MDS specification has been updated to include all of the MDU catalogue ancillaries, and it may not be modified by the administrator or any other user.
