Geometric Shape Calculator vs Dividing Plate Generator

Geometry Math Calculator is a practical tool app focused on calculations for 2D and 3D shapes. It helps you quickly compute common geometric values such as angles, lengths, areas, volumes, and centroids. With an intuitive interface, simple input, and clear results, it is suitable for studying, exams, engineering calculations, and daily use. The app includes nearly 50 built-in shape examples across 7 major categories: triangles, circles/ellipses, polygons, cubes, pyramids/frustums, spheres/ellipsoids, and cylinders/cones/torus. Each shape comes with a diagram and clear parameter descriptions—just enter the known values to get accurate results. For the same shape, the app supports multiple input methods to match different known conditions in problems and real engineering scenarios. For example, a triangle can be defined using SSS (three sides) or SAS (two sides and the included angle), ASA, and more. No extra derivation is needed—simply input the parameters to complete the calculation.

Dividing plates are used with indexing heads to precisely divide a circle for machining tasks like cutting gear teeth or drilling bolt-hole patterns. This app generates full‑scale dividing-plate templates (SVG or PDF) that you can print as drilling guides. Full-scale templates: Generate SVG or PDF templates of your dividing-plate design. Configure the plate outer diameter, center hole, mounting holes, ring margins and hole counts. Use custom values or presets for hole counts per ring. Custom geometry: Enter plate dimensions and hole sizes in inches or millimeters. Include optional 3–6 mounting holes on a specified bolt circle. Preview inner/outer ring margins and indexing hole diameters as you edit. Live preview: See a real-time on-screen preview of the plate drawing. Pinch to zoom and pan to inspect details. Toggle dimension markers, concentric ring outlines and hole indicators on or off for clarity. Export & print: Export your design as a full-scale PDF or SVG file. Print the PDF at 100% scale (no printer scaling) for an accurate drilling template. For large plates, use poster-print mode or split over pages. Built-in calculators: Includes a bolt‑circle hole pattern calculator, a simple indexing calculator, an angle converter and a chord-length calculator. These tools help plan hole layouts and gear indexing on the fly. Help & tips: The in-app Help provides usage instructions and printing tips (e.g. always print at 100%). Ideal for machinists and hobbyists using lathes, mills, CNC or DIY equipment. Download now to design precise drilling templates in minutes!
