1. A method for designing a borehole tubular for use in a borehole, the method comprising:
defining tubular sections that make up the borehole tubular;
defining a downhole operation that will be conducted using the borehole tubular at a first timestamp and a second timestamp;
determining loads that will be applied to each of the tubular sections at respective specific depths along the borehole during the downhole operation at the first timestamp and the second timestamp;
determining a design limit envelope for each of the tubular sections at the first timestamp and the second timestamp based on design parameters of the tubular section and the specific depth of the tubular section at the first timestamp and the second timestamp; and
displaying a four-dimensional (4D) plot of the design limit envelopes of the tubular sections and the loads applied to the tubular sections at the first timestamp and the second timestamp as a function of depth within the borehole on a display such that the loads are displayed as being within or outside of the design limit envelopes for the tubular sections,
wherein a user can customize different visual aspects of the 4D plot of the design limit envelopes, via at least one of a control menu or a dialog window, to confirm if the loads are within the design limit envelopes.
