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. 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.
