Symbol Keys : Universal SKEYs
Universal SKEYs
This facility provides an SKEY suitable for any piping component of generic type PCOM. Fittings with a universal SKEY will be drawn as a ‘ghost' symbol, with no attempt made to represent the exact geometry or dimensions on the isometric plot. The user will need to attach a DRAW drawing, detail plot, or some other method to give the fitting detail. The user can use labelling to identify the fitting connection points.
This feature is particularly useful if the designs use non-standard fittings (such as in the food or pharmaceutical industries), since it makes it possible to automatically produce isometrics of piping networks containing any piping component. The only limitation will be the clarity of components with many connected branches.
The universal SKEY symbol is represented by a circle with lines from its circumference to each connection point. The radius of this circle (default 10mm) is controlled by a percentage scaling factor, SKeyScale, on SDTE elements. For example, SKeyScale = 110% gives a circle radius of 11mm.
To use this facility, set the SKEY attribute to UNIV and, optionally, set the SKeyScale attribute. To output a detail plot, set the DPFN attribute on the SPCO or piping component in the usual way. Alternatively, set the DPFN (Detail Plot File Name) attribute on the SDTE element, in addition to its SKEY and SKeyScale attributes.
