Proper engineering calculations include the validation of the dimensional input of the pressure components being calculated. The assessment based only on values is sometimes difficult due to interpretation or just the amount of dimensions to be checked. The most efficient assessment is done to use a sketch representing the dimension input to scale to the user.

The dimensions entered in PCALC are therefore shown in a dimensional sketch to scale. This sketch can be exported to DXF format for further use in a CAD application. The sketch has a tool to measure dimensions working with the calculations. The dimensions can be checked in the CAD application but also the calculated material and pressure areas, which are regularly used in the calculations.
