ESApro P&ID (Drawing of P&I diagrams and automatic extraction of bill of materials) Piping Spec driven Operations ESApro P&ID supervises the P&I diagram development through the piping spec. Once set ND and class, the user is constantly advised and driven into the line construction and component insertion. The consistency of components with their line class is constantly guaranteed Once inserted components automatically get their characteristic data from the line and the piping class The program includes functions which check the connections of the various line segments one to each other and to the equipment and also deduce the From and To of the lines. The line copying operation is managed by the program in order to avoid mistakes or data inconsistency.   Piping Specs can be freely created in the P&ID environment, or alternatively ESApro Plant Design Piping Specs can be used. User Customizable Graphic Library The program is equipped with a wide library of valves, line components, equipment and instruments in compliance with DIN/ISA/UNI standards. An easy, guided procedure allows the user to insert his own symbols into the library provided that they are available in the DWG format.   Powerful Graphic Functions The graphic functions allows to dramatically reduce the drawing time, to minimize mistakes and to guarantee drawing accuracy. Components automatically orientate and position themselves on the line and then cut it. With one single click an existing valve can quickly be removed and the gap closed or replaced with a different type of valve. Setting of scale factor is provided in order to fit the components and equipment dimensions for aesthetics or clearness purpose. Manual settings are reduced to a minimum thanks to the intelligent management of layers and colours. Components ND and flux direction are automatically displayed on the drawing. Utilities for inserting annotations and cross-references are available. Automatic Tagging A sophisticated tool for the automatic component numeration is provided; the tag format is freely definable by the user. Lines too may automatically assume a tag whose template is beforehand defined by the user suitably combining the line data (ND, class, fluid etc.). The system is capable of managing the tagging modalities provided in the most popular standards, such as ISA and KKS. Great Versatility This program results particularly efficient for making modifications to existing diagrams: Just a single command allows to change the line data (class, ND etc.) with consequent automatic and spec-controlled update of all its components. Data related to each component can be examined and changed at any time. All tags are automatically updated as a consequence of modifications of line data, class or tagging format.   Thanks to the characteristics above it is very easy to develop preliminary diagrams using generic piping specs and components and to specify them in a subsequent phase: everything will be automatically updated. A series of utilities show the list of tags already used, highlight a given line or a component or an instrument loop on the drawing and allow the check out for possible duplicated tags. Furthermore ESApro P&ID manages and controls the development of multi-sheet diagrams within a work group. Shared Project Database Once a new P&ID is filed into a project, or afterwards when submitted to revision, the project database is fed with data of lines, instrument, components and equipment. Datasheet and Hook-up modules work on this database pre-fed by the P&ID, as described below. Automatic List Generation The program generates lists (lines, components, instrumentation, equipment) for a single drawing or for the whole project. A sophisticated tool for the definition of data filtering criteria allows the creation of customized list templates of whatsoever complexity. Lists, besides being available on the drawings under the form of tables, can be redirected to ASCII, Excel and Access files for further processing. User Customizable Environment Users can customize the library of symbols and the material lists as well as the whole graphic environment: title blocks, colours of lines and components, layers and text styles.
