The following tasks are used frequently when you redefine symbols.
Import Symbols
Import an XML-based symbol library so that it can be modified and re-saved or exported to an ASCII file. For more information, see Import a symbol library.
Redefine Isogen Symbols
Create a new symbol based on an existing Isogen symbol.
Establish the basis for a new symbol
Define symbol properties
Draw a basic symbol
Copy and paste symbols
Cut and paste symbols
Transform Symbols
Add and remove symbol points to change the shape of a symbol or add features such as tapping points.
Modify symbol shapes
Add a tapping point
Export Symbol Library
Symbol libraries can be kept on disk in either ASCII or XML format. Most 3D design tools and some 2D isometric drawing generation tools require that you generate an Isogen symbol file before you can use a redefined symbol.
Export symbol data
Export Isogen symbols
Save to the Current Project
Project-based software tools require that the redefined symbol be saved to the current project. Afterwards, the software tool is able to read the symbol data in the project XML file and display the redefined symbols during the creation and editing of the piping object data file.
