Note the licensing on the Hershey library in the source code, which isn't fully compatible with Creative Commons - but the restrictions are very, very slight.Īugust 16, 2019: Optimize file size of hershey.scad for faster loading.Īugust 10, 2019: Added Latin1 accented characters. The "Hello, OpenSCAD!" CGAL render took about three minutes. Unfortunately CGAL rendering is going to be very slow. There is also a function to measure text width: widthHersheyText(text, font=name), with optional size=x and extraSpacing=x parameters. MinimumDistancePrecision=p: set the precision for the forceMinimumDistance option Valign="top"|"baseline"|"center"|"bottom": vertical alignmentĮxtraSpacing=x: add this extra spacing between letters (can be negative)įorceMinimumDistance=d: make sure that the distance (not necessarily horizontal) between successive glyphs is as close to d as reasonably possible use this if you want to draw fat letters that overlap by the same amount, like here Halign="left"|"right"|"center": horizontal alignment The following optional arguments are available: The drawing is done by putting the child object at the two endpoint of a lines and doing a hull() operation. For instance, you can do rounded text via: use ĭrawHersheyFont("Hello, OpenSCAD!", font="Script") sphere(r=2,$fn=16) Ī call to drawHersheyFont() requires a child object that specifies what the drawing is done with. 56 z-probe, v7.62 firmware by DoodleBug, using Ridges-of-Ink Ultraviolet PLA filament part number Q30.06how to clear a jam rather than Clearing filament. This library includes the ASCII portions of the Hershey vector fonts, and draws text using whatever convex shape you specify. But what if you want a different 3D profile, e.g., you want text that looks like it's been machined with a V-shaped bit, or text that is rounded in 3D? The standard OpenSCAD fonts work well for a simple extrusion 3D profile.
