After that, the character and the line are mutually perpendicular. We can rotate the circle 90 degrees first, and then rotate it 360 / $fn / 2 again. Any model that you are ever going to create is going to be 'typed out' in this text editor. The left column is a text editor, where you will be typing the OpenSCAD scripting language to create your models. The starting point of the first line is always, but the above revolve_text module draws its first character at. The first thing that you should notice is that the window of OpenSCAD is divided into two columns. You may observe how the circle module draws a circle. It prevents the above problems, and the model will look neater. What I want here is, the number of characters determines the value of $fn and the character and the line are mutually perpendicular. Sometimes, it's even possible to get unexpected warnings or errors. What problem will it cause? Irregular intersections will increase the complexity of the model, take more time to render, consume more memories, and grow the size of the exported file, such as STL. I intentionally make $fn = 12 to highlight this situation. I found that extruded text with square edges in OpenSCAD is straightforward but I wanted bevelled. The character and the line are not mutually perpendicular. I wanted to 3D print a key tag using someones initials. I created it at my early time on OpenSCAD, so I didn't consider some possible facets of this. My Characters container generator draws like this. Once you've made a text ring, it's admittedly easy to add a circle ring in it, right? After all, you just have to draw a circle and different a smaller circle from it. Depending on the effect you want, a constant character size is also a way you may take. In my another work Character tower generator, I fix the number of characters of a circle. To prevent characters from being too small to print, you may increase the radius if you want to input many characters. If you fix the radius and input more characters, each character will be smaller. Even though the character itself is a plane, wrapping more characters will make the model more like a circle.Ĭharacters container generator is an example taking this implementation. Remember? A circle can be composed of many short lines. If you fix the radius, you fix the circumference, and the number of the characters determines the size of each character. The above code is one of the implementations. SolidPython is a generalization of Phillip Tiefenbachers openscad module, found on Thingiverse.
