## What is Arc Arch Assistant?

A practical arch calculation tool for architects, designers, and builders

Arc Arch Assistant helps you accurately calculate arch structure parameters. From large circular arcs to pointed arches, get complete design parameters and construction drawings with just one tap.

Key Features

Large Arc Layout
Layout large radius arcs in confined spaces with precision. Simply input the chord width and rise height or radius, and the app automatically calculates central angle, arc length, sector area, and other key parameters. Interactive charts show the arc shape visually, while the layout height table provides measurement points with millimeter-level precision.

Pointed Arch Design
Support three classic arch styles: equilateral, lancet, and drop arches. The app automatically calculates inner and outer radii, arch stone parameters, and arc lengths. Customize the number of arch stones on each side, with detailed size specifications for each stone piece, providing precise data for construction.

Side-by-Side Comparison
Compare large arcs and pointed arches side by side. See the differences in arc length, height, and shape under the same span, helping you quickly find the ideal solution for your project needs.

Smart Material Estimation
Input material unit price and waste rate. The app automatically calculates the required number of bricks or wooden boards, total area, and estimated cost, making budget control more accurate.

Professional Export
Export calculation results as PDF drawings or CSV data tables with one tap. PDF includes complete parameter summaries, layout charts, and construction data, ready for direct use on construction sites. Supports both A4 and US Letter paper sizes.

History Management
Automatically saves all calculation results. Bookmark important schemes and review historical data anytime to avoid repeated calculations.
