Before attempting to create a symbol in PDMS the user should know the hierarchy where to create this symbols so that it can be used to create ‘SLAB’ in the views.
All the symbols for BHEL are stored in the following hierarchy
DEPT - / MASTER-LIBRARIES
LIB - /BHEL-LIB
SYLB - /BHEL-GEN
SYTM- /XXX (The name of the Symbolic Template)
To create a new SYLB first create backing sheet for the symbol library. The sheet limits has to be checked for its size before it is created. It is recommended to create the symbols using the soft copy.
The procedure to create the symbol is:
Steps for creating Symbol
Step 1: Open the drawing in AutoCAD.
Step 2: At command line give the command ‘DDATTDEF’.
Step 3: A form will appear, toggle on the invisible button.
Step 4: Give the Tag as ‘PDMS_NAME’.
Step 5: Select the pick option and pick the required point for the base point of symbol and Press ‘OK’.
Step 6.: The PDMS_NAME appears on the screen at the picked up point.
Step 7: Now previous point. Create a block with some name and select insertion base point same as
Step 8: Select the symbol along with the PDMS_NAME label.
Step 9: Insert the block while inserting the block you will be prompted for various details, ignore all except PDMS_NAME. At PDMS_NAME, give the name of the SYTM. This will be your name of the symbol.
Step 10: Appload the lisp files from C:\cadcentre\pdms11.2\autodraftR13\*.Lsp.`
Step 11: At command line type ‘PDMS_SYMBOLS’.
Step 12: Give the Draft Symbol Library name.
Step 13: Give the draft command file name as C: \temp\some relevant file name.
Step 14: Close the AutoCAD drawing.
Step 15: Login to PDMS Draft Module.
Step 16: Give the following command at command line ‘Tol 0.01’(this sets the precision to 0.01).
Step 17: $m/c:\temp\ the file name you have given.
The symbol library is created in your respective library (SYLB).
Note: The size of the backing sheet for the symbol library (SYLB) and the backing sheet should be same If you want to position the SYTM using the cursor in your symbolic library, be at the sytm and give the following command.
U should run this macro in draft administrator symbol library, u should created symbol library with same name in draft before run this macro .
