Delete Items

To delete items from a drawing use the shortcut menus available from the Engineering Explorer or The Drawing Page. These can be accessed after selecting single or multiple items. Refer to Delete Drawing Objects.

The consequences of deleting items in AVEVA P&ID vary because of the many different situations encountered. The results deleting using the AVEVA P&ID facilities are dictated by the item types involved.

In general, items associated together are deleted together.

Deleting an equipment item such as a vessel, with associated nozzles, pipe trim and sub-equipment from the explorer, will remove everything.

• When deleting an inline item from a pipe with tracing, select the tracing around the item as well as the item itself. Pipes are closed when inline items are deleted. Labels are removed automatically as appropriate or can be selectively removed.

• When a labelled reducer is deleted, the line is closed and the user prompted for the size to retain. The size of the remaining pipe is revised accordingly, and cascades across pipe boundaries as necessary.

• Deleting an inline instrument also removes the label balloon, then closes the line and removes labels as normal.

• Non-AVEVA P&ID entities/elements are deleted as they would be in normal AutoCAD.

• Deleting a Pipe which crosses over another pipe will only close the break in the line if the break symbols are selected.

• Deleting an instrument also removes any associated I/O rockets.

• Nozzle labels are not automatically deleted when the label of the associated equipment is deleted.

• If a trim label is deleted, associated trim pipe labels are also deleted.

• If the Number or Letter components of an equipment label are deleted, the rest of the label will be deleted also.

• Each part of an SPP label is placed separately and may be deleted separately. If a part of an SPP label is deleted and as a result the label is now a duplicate of an SPP label on another project drawing, an error or warning message may be displayed if the Prevent or Warn option is selected in the Miscellaneous - Settings Sub-Category of AVEVA P&ID Administrator program.

• A title block of a drawing sheet may not be deleted if that drawing sheet has attribute values that are inherited by items on the drawing. This is to prevent the accidental deletion of large amounts of label data should the title block be inadvertently deleted. Before such a title block can be deleted, the project settings must be changed to remove the inheritance, and the previously inherited sheet attribute values set to null.
