The Programmable Macro Language (PML) is a domain specific language developed by AVEVA to customize AVEVA products. AVEVA™ Documentation AVEVA Programmable Macro Language Guide | PDF - Scribd
This is where come into play. By automating repetitive tasks, macros transform hours of tedious manual drafting into seconds of background processing. Whether you are a CAD manager looking to standardize company workflows or a designer aiming to boost daily productivity, understanding how to leverage macros is a game-changing skill. What is an AVEVA E3D Macro?
Boom. A column appears. But that’s just the starting point.
For enterprise-level development, moving from PML to C# via the AVEVA Open API offers massive advantages, including faster execution speeds, source control integration (Git), and access to third-party .NET libraries. aveva e3d macros
Run a macro that loops through every equipment item in your site, checking for missing attributes (e.g., PURPOSE field empty) and outputs errors to a text file.
: Sites like 3D Software Customization offer free sample macros for learning tasks like clash detection or attribute modification.

To write effective E3D macros, you must understand how PML interacts with the model data. Here are the core building blocks: 1. Variables and Data Types
Create a new text file named create_equipment.mac . Copy and paste the following PML code, which automates the creation of a standard equipment cylinder:
Always verify the current element ( CE ) type before executing modifications to prevent accidental data corruption. Transitioning from PML to .NET Customization Whether you are a CAD manager looking to
Type $M followed by the full file path of the macro file. Example: $M C:\AVEVA_Macros\CreateStandardVessel.pmlmac
: Your stage. This is where you call macros using the syntax $m C:\Path\YourMacro.txt PML (Programmable Macro Language)
IF (!DIAMETER > 5000) THEN $M special_foundation.mac ELSE $M standard_foundation.mac ENDIF
PML has two primary versions. handles lower-level command execution and calculations; for example, moving an object in a certain direction: MOVE BY NORTH 100 VAR !length ( 2 + 3 ) . PML2 introduces object-oriented capabilities for building forms, custom menus, and user interfaces. A PML2 example: !s = object selection() .
