Notes:
1.
Replace the ** characters in the symbol key with one of the following end condition identifiers:
BW for butt weld
CP for compression
SW for socket weld
FL for flanged
SC for screwed
PL for plain
2.
To use this symbol, the p-points must be arranged as shown in the following diagram:
3.
To use this symbol, the p-points must be arranged as shown in the following diagram:
Note:
That the horizontal offset may be zero; i.e. P0, P1, P2 and P3 may be coplanar.
4.
To use this symbol, the p-points must be arranged as shown in the following diagram:
Note:
That the horizontal offset may be zero; i.e. P0 and P1 (and similarly P2 and P3) may be coincident.
5.
If an orientation p-point (P3) is present in the point set and is oriented away from the XYZ axes, then the orientation of this p-point will be shown on the isometric.
6.
Instrument dials can have a P3 with an unset bore for orienting the dial. This p-point will normally be positioned perpendicular to the dial face, on the dial axis. A message will be output near the component showing the orientation of P3.
7.
P-Point 11 is the Spindle attachment point and its PURP attribute should be set to 'SPIN'. These Multiport Valves may have up to two flushing/draining connections: -
•
These must be P-Point 9 and P-Point 10.
•
The isometric will only show a symbolic line and a note CONT TO "name" for each connection.
•
There will be no materials or isometric representation of the branch connection to these points.
