Gaussmeter NS pole vs HoleCopy

Magnetic field measurement in microteslas by magnetic sensor. Put on the screen and determine N-pole or S-pole of the magnet.

Replacing a bracket, a hinge or a speaker plate? The holes are the hard part. Measuring them one by one with a ruler stacks up error until the last hole is off. HoleCopy copies the pattern instead of measuring it: lay the old part on the reference sheet, take one photo, and get every hole center and diameter in real millimetres. HOW IT WORKS 1. Print the A4 or US Letter reference sheet at 100% 2. Lay the old part on the sheet and take one photo 3. HoleCopy squares up the perspective and detects round through-holes 4. Check the result on screen: move a center, resize a hole, add one the camera missed, delete one it invented 5. Export a true 1:1 PDF or SVG, tape it to the new material and drill WHAT YOU CAN DO BEFORE EXPORTING Photographing the part, perspective correction, hole detection, editing and the output preview all work with any part you try. You can see whether HoleCopy reads your part correctly before you export anything. WHAT UNLOCKING EXPORT ADDS Saving, sharing and AirPrinting the actual-size PDF or SVG, as often as you like. That includes patterns larger than one sheet, split across pages with overlap marks and alignment crosses, ready to tape together. BUILT FOR THE WORKSHOP - Mirror the template for the back side of a part - SVG export for vector programs - A 100 mm and 1 inch check bar on every page, so you can confirm your printer did not scale it - Everything is processed on your device; photos never leave it WHO IT IS FOR Furniture repair, woodworking and metalwork DIY: brackets, hinges, handles, table legs, speaker cabinets, control panels, car or motorcycle mounts, gasket and flange hole patterns. BEFORE YOU DRILL HoleCopy works with flat parts and round through-holes of 3 mm and larger, when the part and the reference sheet fit in one photo. It is a positioning aid, not a guarantee of precision: check that the printed bar measures exactly 100 mm and drill a small pilot hole first when it matters. Not intended for safety-critical parts.
