Notes:
1.
To allow for the amount of pipe that normally passes through the component before cutting or grinding off, a cutting allowance is included if the LOOSE attribute of the flange is set to TRUE. This allowance is determined by the value of the ALLO attribute, if set. If the ALLO attribute is not set (or set to zero), the allowance will default to 150mm. However, this default value can be altered by the LOOSEFLANGEALLOWANCE command.
2.
The system used by previous version of the software (using ‘intuitive’ P3 points) is still supported.
3.
To be used in conjunction with LJSE symbols FLRG or FLSE.
4.
Reducing flanges will have clarifying text plotted on the isometric drawing to highlight their presence.
5.
Orifice flanges will have clarifying text plotted on the isometric drawing to highlight their presence.
