Hole Pattern Programming App

Features
Read full description

Hole Pattern Programming App is a powerful, professional, and easy-to-use app designed for engineers, machinists, VMC programmers, VMC operators, CAD designers, fabrication professionals, and students who require accurate, error-free hole layout calculations and VMC programming support. The app supports virtually every type of hole arrangement — from simple linear rows to advanced multi-PCD mesh structures. Whether you are working on flanges, plates, jigs, fixtures, decorative panels, or precision mechanical parts, this tool simplifies even the most complex drilling and tapping calculations. Simply enter a few key dimensions and the app instantly generates: • Exact X–Y coordinates • Visual preview of the hole layout • Hole sequence numbering • Optional VMC drilling and tapping programs Even if your hole center is not at X0, Y0, you can change the origin and the app will automatically recalculate all coordinates accurately. Supported Hole Patterns • Single and Multiple PCD (Pitch Circle Diameter) • Full circle or limited angular span PCD • Linear patterns (horizontal, vertical, or angled) • Circular bolt circle layouts • Rectangular grids • Border-only hole layouts • Angular linear patterns • Mesh / lattice structures using multiple PCDs Key Features PCD Hole Patterns Create full or partial angular span hole arrangements on single or multiple PCDs. Linear Hole Patterns Generate straight or angled rows of holes at any custom angle. Rectangular Patterns Fill complete rectangular areas or generate holes only along borders. Mesh / Lattice Structures Create complex multi-PCD patterns for structural and decorative designs. Custom Center Adjustment Change origin (X0, Y0) and automatically recalculate all coordinates. Coordinates & Visual Preview Get precise X-Y coordinates with a visual layout of every hole. Hole Sequence Numbering Automatic numbering from 1 to total holes for easy reference. VMC Programming Support Generate ready-to-use drilling, center drilling, and tapping programs. Editable Drill & Tap Parameters Customize drill depth, tap depth, pitch, and sequence. Flexible Output Options Copy coordinates, copy full VMC program, or share using the Share button. Automatic Error Handling If required inputs are missing, the app shows clear messages instead of crashing. Metric & Imperial Units Work seamlessly in millimeters (mm) or inches. User-Friendly Interface Designed for fast use in workshop, field, or office environments. Practical Use Cases Flange & Bolt Circle Layouts – Design precise PCD holes with full or partial spans. Linear Hole Rows – Create straight or angled hole rows on plates and sheets. Rectangular Plates – Fill areas or generate border-only patterns. Mesh / Lattice Designs – Complex structural or decorative layouts. Custom Center Workflows – Adjust coordinates to match machine zero or fixture setup. Workshop & CAD Planning – Use coordinates for manual drilling or CAD input. VMC / CNC Programming – Instantly generate editable drilling and tapping programs. Why Choose Hole Pattern Programming App? Supports all major hole layout types – linear, circular, rectangular, border-only, angular, multi-PCD, and mesh. Ensures error-free and reliable calculations. Saves time compared to manual methods or spreadsheets. Provides coordinates + visual preview for complete clarity. Generates CNC-ready VMC programs. Fully customizable and easy to share. Stable and safe – guides users instead of crashing. Use Hole Pattern Programming App today and simplify your machining and hole layout workflow. From single PCD to complex multi-pattern designs, from coordinates to CNC programs — everything you need is now available in one powerful professional tool.

Convert any engineering sketch to a CAD-ready DXF file - in seconds. SketchDXF: AI-Powered CAD Converter The fastest way from paper sketch to machining. No CAD software. No training. Just snap a photo. Built for the Workshop, Not the Design Studio • Convert hand-drawn parts into CAD-ready DXF files • Create DXF files without CAD software • Perfect for CNC, laser cutting, and fabrication workflows How It Works Step 1 - Sketch It Draw your part on white paper. Add dimensions such as width, height, diameter, radius (R), hole positions, slots, and bend lines. Step 2 - Scan It Take a photo or upload your drawing. SketchDXF detects geometry, dimensions, and engineering annotations. Step 3 - Download DXF Receive a CAD-compatible DXF file in seconds, ready for CAD software or CNC workflows. Supported Drawing Types SketchDXF converts 2D engineering drawings into CAD-ready DXF files. Supported inputs: • Hand-drawn 2D engineering sketches • PDF engineering drawings • Technical 2D drawings of flat sheet metal parts Important SketchDXF is designed for 2D engineering drawings only. It does not convert: • Photos of real-world objects • 3D parts or assemblies • Machines or equipment • Furniture or products • Random shop floor photographs If you upload a photograph of a physical object, the AI cannot generate an accurate DXF because it is trained to interpret 2D engineering drawings, not 3D objects. What the AI Understands • Circles, holes, arcs, slots, rectangles, polygons and ellipses • Corner radii, chamfers and rotation angles • Fold/bend lines and bend angles • Countersinks (CSK), counterbores (CBORE) and thread specs (M6x1.0) • Bolt circle patterns • Tolerances and GD&T annotations Professional DXF Output • CAD-compatible DXF • Layers: CUT, HOLES, FOLD, CHAMFER and DETAIL • Optional dimension annotations • 1:1 scale output In-App CAD Preview • Preview generated drawings • Zoom and inspect details • Switch between Drawing, Details and Original Sketch Human Review (Starter & Pro) If the AI cannot generate the correct DXF, request a Human Review directly in the app. • Manual DXF creation by our design team • Receive the corrected DXF back in the app • Available with Starter and Pro only • Not available on the Free plan Cloud Sync & History • Secure scan history • Access scans from any device • View original sketch and DXF together Free to Start • Free - 2 AI scans/month • Starter - 10 scans/month or 120/year • Pro - 25 scans/month or 300/year Subscriptions are managed through your App Store account. Who Uses SketchDXF? Sheet Metal Fabricators • CNC & Laser Cutting Operators • Mechanical Engineers • Product Designers • Manufacturing Teams • Engineering Students • Toolmakers Stop redrawing. Start scanning. Download SketchDXF and convert your first engineering drawing in under 60 seconds.
