A drawing generated by Smart Isometrics produces standard symbols for all components. These symbols can be customized to suit your specific project requirements using the companion product Symbol Editor.

All components generated by Isogen are defined by a unique code called a symbol key (SKEY). The graphical symbols drawn on the isometric are based on these component SKEYs. To change the shape of the symbol, you must modify its SKEY. Isogen has a standard library of SKEYs, most of which can be redefined. It is also possible to create your own SKEY, presuming that it is based on an existing standard SKEY.

The symbol editor software provides a convenient way of redefining existing XML-based or ASCII symbol files and saving the changes to a project XML file. Smart Isometrics can read the redefined symbol data in the project XML file and display the redefined symbols during the creation and editing of the piping object data file. Redefined symbols can also be output on Smart Isometrics-generated drawings, depending on the settings you define on the Generate Drawings dialog box .

  • To retrieve the symbol data stored in the project .xml file, Smart Isometrics must be connected to the same project that was used by the symbol editor software to redefine the symbol.

  • Not all symbol shapes can be redefined. This restriction applies mainly to pipe-based fittings such as elbows, pulled bends, tees, and crosses.

  • Symbol Editor is installed automatically during a default setup of Smart Isometrics. If you did not perform a default setup of the software, see Add Individual Tools After Installing the Core Product in the Smart Isometrics Installation Help.

Understanding SKEYs

All components generated by Isogen are defined by a two to four-character code called an SKEY, or symbol key. The first two characters define the type of component, such as globe valve or concentric reducer, and the last two characters define the end type, such as flanged, butt welded, or screwed. For example, the SKEY VGFL denotes a flanged (FL) globe valve (VG). You can specify an appropriate end condition by replacing the ** characters in the SKEY with one of the set of characters listed in the table below.

SKEY Characters

End Condition

BW

Butt Weld

CP

Compression

SW

FL

Flanged

SC

BS / SB

Ball and Socket (used on fixed length type pipe work)

GF

Gland (used on fixed length type pipe work)

  • Components such as miter bends and pulled bends can have special characters in the SKEY to affect its shape, as detailed below.

    • To denote the number of segments, replace the At sign (@) in the SKEY with an integer value in the range 1 to 9, inclusive.

    • To denote the bend radius, replace the Plus sign (+) in the SKEY with an integer value in the range 1 to 9, inclusive. This is for identification only and is not used for pipe length calculations.
