Export a P&ID Drawing to AutoCAD


Export a P&ID drawing file to an AutoCAD drawing file format without losing the visual fidelity of the P&ID drawing.

The exported drawing retains all P&ID components and annotations as AutoCAD blocks. All P&ID schematic lines are retained as AutoCAD lines. You can then use AutoCAD to open, view, edit, and plot the exported P&ID DWG files.

Avoid Proxy Graphics

You can use AutoCAD and AutoCAD P&ID to open and view drawing files in the DWG file format. However, you cannot use AutoCAD to edit custom objects created in P&ID, such as pipe lines, nozzles, and other equipment. AutoCAD treats such custom objects as proxy graphics. You cannot edit or modify proxy graphics using AutoCAD.

To open a P&ID drawing in AutoCAD, first export the drawing file to AutoCAD. Exporting the drawing ensures that the AutoCAD drawing looks identical to the P&ID drawing. Moreover, the custom objects in P&ID are converted to AutoCAD blocks and lines instead of proxy graphics. You can then edit these blocks and lines in AutoCAD.

For more information about proxy graphics, see “Work With Custom and Proxy Graphics” in the AutoCAD Help system.

Maintain Visual Fidelity

In an exported drawing, components (equipment, nozzles, instruments, inline components, and non-engineering items) look exactly like those in the original P&ID drawing. All the information that is displayed in the drawing (such as color, position, and size) is retained in the exported drawing.

For schematic lines, all visual information (such as color, linetype, line weight, and so on) is retained in the AutoCAD lines.

Annotations placed on components and lines are exported as AutoCAD blocks. They retain their position, size, and orientation in the drawing.

Save, View, Edit, Plot as AutoCAD Files

To export a P&ID drawing file, save it in one of the following AutoCAD file formats:

After exporting the P&ID drawing to AutoCAD, you can view, edit, and plot the drawing as you would any AutoCAD drawing.

All the layers in a P&ID drawing are retained in the AutoCAD file format.

Similarly, all model space, paper spaces, and any user-created layouts are available in the AutoCAD file format.


It is recommended that you use the EXPORTTOAUTOCAD command to export layouts correctly. Using an AutoCAD command, such as EXPORTLAYOUT, does not export all P&ID layers correctly and might result in lost data or exploded objects.
