Upgrade AutoCAD Drawings

Existing "dumb" AutoCAD drawings can be upgraded to "intelligent" AVEVA P&ID drawings by using a combination of the AVEVA P&ID Drawing Upgrade Utility and commands within AVEVA P&ID.

In order for the upgrade procedure to run as smoothly as possible, it is recommenced that a number of guidelines be followed when drafting the AutoCAD drawings to be upgraded. Refer to AutoCAD Drafting Guidelines.

Upgrade AutoCAD Lines to AVEVA P&ID Pipes, Process Links and Signal Lines

AutoCAD lines may optionally be mapped to AVEVA P&ID Pipe Types and Signal Line Types using the AVEVA P&ID Drawing Upgrade Utility.

Refer to Assign P&ID Pipe Types to AutoCAD Line Types and Assign P&ID Signal Line Types to AutoCAD Line Types.

If inline items are to be upgraded as part of the line upgrade procedure, they must be mapped to an AVEVA P&ID Symbol in the project using the AVEVA P&ID Drawing Upgrade Utility.

Refer to Assign P&ID Symbol Names to AutoCAD Blocks.

A procedure may then be carried out in AVEVA P&ID to convert AutoCAD lines to the Pipe and Signal Line Types they have been mapped to.

See Assign Mapped Pipe Types and Signal Types to Lines.

No further procedures are required to upgrade AutoCAD lines to Signal Lines and Process Links. To complete the conversion of lines to Pipes:

1. The start and end points of the line, and the entities of the line that are to be upgraded must be specified. An AVEVA P&ID pipe is then created from the selected segments and symbols.

   Note: Lines will be upgraded to an AVEVA P&ID Pipe of the current default Pipe Type unless a Pipe Type has already been assigned to it.

2. Any entities accidentally selected for inclusion in the upgraded line can be removed from it.

3. Tees must then be added to the junctions of upgraded line segments.

4. Flow arrows can then be added to the upgraded line.

5. When flow arrows are added they automatically point in the direction that the pipe was drawn in. As this may not be the flow direction, pipe segments may be reversed so that flow arrows point in the correct direction.

6. The label balloons and connecting leader lines of inline instruments must then be associated with the instruments.

Upgrade AutoCAD Blocks to AVEVA P&ID Symbols

There are four ways of converting AutoCAD blocks to AVEVA P&ID symbols:

• In the AVEVA P&ID Drawing Upgrade Utility assign AVEVA P&ID Item Types and symbol property data to an AutoCAD blocks and then add those blocks as a new AVEVA P&ID Symbols to the project, refer to Assign P&ID Item Types and Symbol Data to AutoCAD Blocks.

  Like any other project symbols, they can then be added to a drawing, or selected to convert AutoCAD blocks.

• Map blocks to AVEVA P&ID Symbols using the AVEVA P&ID Drawing Upgrade Utility, Assign P&ID Symbol Names to AutoCAD Blocks, and then upgrading them as part of the procedure for converting AutoCAD lines into AVEVA P&ID pipes.

• Map blocks to AVEVA P&ID Symbols using the AVEVA P&ID Drawing Upgrade Utility and then upgrading all mapped blocks on a drawing using a procedure in AVEVA P&ID.

• Individually upgrading blocks in a drawing by specifying a project Symbol for them to be converted to.

Upgrade AutoCAD Text to AVEVA P&ID Labels

A number of commands are provided in AVEVA P&ID to convert AutoCAD text to labels for different types of AVEVA P&ID items.

Refer to Upgrade Text to Labels.

View Upgraded and Un-upgraded Entities

A utility is provided which can be used to easily visually identify those items on drawing which have and have not been upgraded.

Refer to View Upgraded Entities.
