![]() ![]() Greater accuracy than you could ever manufacture to. Position to an accuracy of plus or minus 3 microns, you can model to a much Pretty darn accurate and given that the best CNC machining centres can Say you extrude a vertex 0.0001mmĪlong the X-axis you have set its position 1/10th of a micron from the original. Get? Blender allows you to numerically input the distance of vertices to the If we consider one blender unit to equal one millimetre how accurate can we If you were considering modelling a precision component or assembly, beingĪble to model down to sub micron accuracy would be a distinct advantage. ![]() One micron is equal to 0.001 millimeter.Įxcerpt from Precision Modeling by Robert Burke (So how big should I make a blender unit? Well-known technique is to handle this is extra size of cutting dimension or holes. Honestly those experiences forced me to have better tools that have great accuracy. I can cut a piece or drill a hole within 0.5 mm accuracy using hand tools. Anything that goes below one millimeter demands precision cutting and finish works that require decent equipment and tools. The smallest unit of most wood workings is millimeter. My improvised work bench made out of an old fuel tank hasn’t been secured on the floor yet. How many experts in trade know how to construct the right angle without using square or straight edge? Forming the right angle that produces vertical and horizontal reference point is the base of serious precision work. Furniture and door / window frame are few milliliters off. Most buildings and houses are few centimeters off from design specification that is acceptable error. ![]()
