## Description

Dummy Support Calculator is a pipe fabrication calculator for dummy supports, saddle cuts, fishmouth cuts, elbow trunnions, and elbow miter layout work.<br><br>The app helps calculate the cut line where a dummy pipe meets a run pipe or elbow surface, then provides practical dimensions, development data, and marking information for shop-floor fabrication.<br><br>Supported calculations:<br>- Straight Dummy: fishmouth saddle cut for a dummy pipe welded to a horizontal run pipe<br>- Elbow Trunnion: dummy support layout on an elbow surface<br>- Elbow Miter: cutting data for standard 45° and 90° elbows<br><br>Key features:<br>- NPS pipe size selection<br>- Automatic pipe outside diameter reference<br>- Center-height based dummy length calculation<br>- 2D section view with dimensions<br>- Saddle depth and dummy circumference calculation<br>- Development graph for marking<br>- Coordinate table for layout points<br>- Marking PDF export and sharing<br><br>This app is designed for pipe fitters, fabricators, welders, piping engineers, and field workers who need quick layout support for pipe dummy supports and saddle-cut marking.<br><br>Common use cases:<br>- Pipe dummy support fabrication<br>- Saddle cut layout<br>- Fishmouth cut calculation<br>- Pipe support marking<br>- Elbow trunnion layout<br>- Elbow miter cutting<br>- Workshop and field measurement support<br><br>Core calculations are processed on the device. The app is intended as a practical fabrication aid and should be used with proper engineering review, site standards, and field verification.
