Fire Sprinkler Heads Distribution Lisp for AutoCAD: Laying out fire sprinkler heads in AutoCAD is technique  which is very boring and take a lot of time to do it manually. Fire Sprinkler Distribution Lisp is tool which make this process easy by spacing and orienting sprinkler head blocks in proper way along the path we select, this is very useful for peoples who work in MEP engineers, fire-protection designers, and CAD drafters. when we run this simple Auto LISP routine we get uniform coverage and we do not have to do copy-paste workflows which is very tedious job.

Key Features

• Equal Spacing:
  Specify the number of sprinkler heads or exact interval distance to achieve consistent layout along straight or curved pipes.
• Block Compatibility:
  Works with any sprinkler head block—whether embedded in the drawing or referenced as an external Xref.
• Dynamic Alignment:
  Aligns each head perpendicular to the pipe direction, maintaining correct orientation for plan views.
• Start/End Offsets:
  Define buffer distances from the pipe endpoints to avoid placing heads too close to walls or fittings.
• Interactive Prompts:
  Guided command-line prompts walk you through selecting the pipe polyline, choosing block name, and entering spacing parameters.
• No Installation Hassle:
  Simply drag-and-drop the .lsp file into your drawing or load via APPLOAD; ready to use immediately.
