Below is an alternate method of embedding lettering into an OpenSCAD project. A custom dwf file of the lettering could be generated and extruded, but a more generic, reusable method would be preferable. ![]() It's just when I try to segment this particular font that OpenSCAD fails. A smooth font was necessary for a few future projects I'm working on. Extruding and rendering the font without breaking it into segments works just fine. I don't know if I can upload the font, but it's available for download for free from here: Link to Ringbearer Font. This effects other letters as well, but only seems to be a problem with the "Ringbearer" font I'm trying to use. However, the F6 preview always drops the left side of the letter "b" and displays the error "ERROR: The given mesh is not closed! Unable to convert to CGAL_Nef_Polyhedron". Should fix the repeatedly long startup-time on each execution. As far as I am aware I used a standard include, I was under the impression that the OpenSCAD font list was now fully available in customizer. It's not much use in this example, but in the larger one, I'm translating and rotating each segment. e1) Fix location of cache folder (Windows ). Extrude the "segment" of text to the requested thicknessĪll this does is generate a line of text (just "b", in this case), cuts it into "segments", then extrudes each segment in-place. Segment_x_offset = segment_number * segment_width Calculate the x offset of the current "segment" of text This is part of a much larger project, but I've been able to simplify the problem down to the following snippet of code. Eg.So, I'm doing some odd things with text extrusion and (perhaps not surprisingly) having some odd issues in OpenSCAD. The $fn argument makes the circle smoother - the circle is represented as a regular polygon and $fn specifies the number of its edges. Took a bit to skim through the 2511 but the issue was.I needed to install the font as an administrator. You can clone it and play with it yourself. The reason for your results seems to be that when y0, your intersection results in an empty object, hence nothing is subtracted. The complete source code is available in a git repo linked at the end of the article. There are example snippets of code throughout the article. Real world example (colorFabb COPPERFILL Ø 2,85 m / 4m): We can model it in the dimensions of a real reel and than scale it to the final model size. On top of it we would like to put a logo and some abbreviation of the material name. We would like to get a shape that roughly looks like a filament reel but is not too complex. F6 - render the model (do this before saving to STL)Ĭomments are C-like, ie.Basically you write your code in one pane and see the model in the other. Please refer to the OpenSCAD User Manual and the example models for the basics of OpenSCAD. Then I realized I've already done something similar a few years ago in open-source RenderMan implementation Pixie for the university projected on the Shading Languages course. when compared to Blender with its overly complex UI with hard learning curve.Īfter I finished this project it felt vary natual and familiar. Hot Network Questions Is a reason given for why the sacrifice of the Red Heifer was made at the Mt. OpenSCAD: How to avoid extra grouping in CSG tree. OpenSCAD: How to draw a cylinder from vector to vector 0. This is a different to the triangle mesh representation where only the border, not the solid itself is described.įor programmers the whole concept is much more intuitive and natural, eg. OpenSCAD difference/intersection not working. The model is described by a custom programming language. we the model from primitive parts (cube, 2D polygon, linear extrusion), by applying transformations (traslate, scale, rotate) and set operations (union, intersection, difference). It allows to make 3D models using the Constructive Solid Geometry (CSG) and procedural modeling paradigms. Since I like programming more than GUI modeling tools and mouse clicking, I decided to try OpenSCAD. Imagine a big poster to present a collection of filament materials and for each there's a nice small tangible artifact made of that material. Different fonts can vary somewhat and may not fill the size specified exactly. This little weekend project was done for Svět 3D Tisku (3D Print World), a local 3D print company ran by my parents, for 3D Expo Prague 2016. The text module creates text as a 2D geometric object, using fonts. Our today's goal is to prepare around 20 3D-printed things representing filament reels, each with a inset logo and a short name of the material.
