Smart Pipe Labeling

Streamline your AutoCAD workflow with intelligent auto-updates.

The Challenge

In traditional AutoCAD workflows, placing blocks and manually typing attributes for pipe sizes is repetitive and prone to human error. You have to place the block, then run a separate command to update the pipe data.

How It Works

1
Automatic Detection: Simply select the pipe line. The tool immediately extracts the polyline width and the layer suffix (SP, WP, RP, VP).
2
Live Processing: The script multiplies the width by 10 and formats it automatically (e.g., "%%C100 SP") in real-time.
3
One-Click Placement: As you drag your mouse, the block is already populated with the correct data. No post-processing required.

Key Features

Usage Instructions

  1. Load the LISP file using the APPLOAD command.
  2. Type AOO in the command line.
  3. Select your pipe curve.
  4. Move, rotate, and offset your arrow block—the text updates instantly!
  5. Click to place the block.
