Refer to EPLANT-Piping Basic Tutorial.
The isometric representation is generated using the symbology blocks contained in the project isometric symbology directory, configured in the project setup (default \PD\ISO\). Each 3D piping component has an isometric symbol associated to it, different when changing the end code. The user can modify those symbols, and can also use a different symbology directory.
The block name has the first part of the name equal to the Generic Code (three
characters) plus the isometric equivalent end code associated to the code of end 1
(up to four characters, generally two), for
example GATRF is the block name of the symbol of a gate valve with flanged RF ends.
But the same block name is used also for flanges FF ends because the equivalente iso end code
associated to both end codes is the same and equal to RF. It is the code defined in the
ISO_SYM field in the system table /STD/END.DBF
This mechanism allows to reduce the quantity of isometric symbols.
Valve operators are the only exception, whose names are made only with the component
code.
If the end code associated to the second connection point is different from the first one,
typically for flanges and olets, the isometric symbol name will also have the second
end code added to it.
If during the isometric extraction the system can't locate the required block, a warning is issued and the special DUM_ISO block is used. In this case, the required symbol must be defined and the isometric extracted again.
Each new symbol must be generated as a special block using the menu command: PD_ISO / Block Definition, from a 3D model or isometric file:
