Resolve Snapping Issue after Symbols are Added to the Drawing Canvas

A snapping issue can occur after inserting symbols on the drawing canvas and then attempting to connect signal lines to them using the snap settings.

In certain cases, when the symbol is selected with the Osnap marker displayed, a different snap point on the symbol is selected.

To resolve the issue, a VPB command can be added to the application by editing and appending the ACADDOC.LSP lisp routine file which is delivered with AVEVA P&ID.

1. Navigate to the AVEVA P&ID Bin folder. For example:

   <<DRIVE>>:\Program Files\AVEVA\P&ID 12.2.SP2\Install\AutoCad\Bin

   If the location is inaccessible, copy the ACADDOC.LSP file to the AVEVA P&ID project folder. For example:

   <<Project Location>>\AUTOCAD\PROJMET\

   

2. Open the ACADDOC.LSP file and add the following text:

   ; Change the view to the front

   (defun C:VPB ()

   (vl-load-com)

   (command "._-VPOINT" "R" 270 0)

   (command "._-VPOINT" "R" 270 90)

   (command "._ZOOM" "P")

   (command "._ZOOM" "P")

   (princ)

   )

   For example:

   

3. To resolve the issue on the drawing using AVEVA P&ID, press <Esc> to cancel the command.

4. Enter VPB at the command prompt. The correct snap point on the symbol will be selected when attempting to connect signal lines to added symbols.
