Defining a Distance

Distance in a PTAXI element is defined by the PDISTANCE keyword (minimum abbreviation PDIS) followed by a value or a parameter function. For example:


PDIS 100	sets P-point position to 100 units along defined axis
PDIS (PARAM[1]	sets P-point position to (value of first component parameter) units along defined axis

If you do not define the distance, a value of zero is assumed.

For the reducing tee shown in Figure 5:2.: Example of Parameterisation for a Reducing Tee, the position of P-point 3 could be defined by the commands:

PAXI X
PDIS (PARAM[2])

since PARAM 2 is the dimension called ‘height’.
