A suitable 3D Pointset for the reducing tee shown in the Example of Parameterization for a Reducing Tee image would be created as follows:
|
NEW PTSET /RTPTSE |
Create new 3D Pointset |
|
NEW PTAX |
Create axial P-point element |
|
NUMBER 1 |
P1 |
|
PAXI -Y |
Direction of P1 along negative Y axis |
|
PDIS (PARA[5]) |
Distance along axis from P0 = half overall length |
|
PCON (PARA[7]) |
Connection type at P1 |
|
PBOR (PARA[1]) |
Nominal bore at P1 |
|
NEW PTAX |
|
|
NUM 2 PAXI Y PDIS (PARA[5]) PCON (PARA[7]) PBOR (PARA[1]) |
|
|
NEW PTAX |
|
|
NUM 3 PAXI X PDIS (PARA[6]) PCON (PARA[8]) PBOR (PARA[3]) |
|
Note:
All the P-point attributes may be defined on one line. The last P-point (P3) could
alternatively be defined as a Cartesian P-point:
|
NEW PTCAR |
|
NUM 3 PCON (PARA[8]) PBOR (PARA[3]) |
|
PX (PARA[6]) PY 0 PZ 0 |
|
PTCDIR X |
Further examples of the construction of typical 3D Pointsets are given in Appendix C. Reference information concerning the setting up of the P-point attributes is given in the following subsections.
