When there is a need to use a bolting catalogue with both Imperial and Metric projects, there is not always a direct conversion from one system to the other. For example, a 1/2 inch bolt may convert to a 12mm rather than a 13mm one.
To overcome the problem, User-defined Nominal Bolting tables for diameter and length can be set up, as for the User-defined Nominal Bore table. The PURP attribute is set to BDIA for bolt diameters and BLEN for bolt lengths.
For most users, the requirement is adding or removing a few bores. For this purpose, a macro of standard PDMS bores is provided (nominal_bore.mac), which enables a user to edit the values concerned and then input the User-defined Nominal Bore table into the catalogue.
