run one after the other removes internal faces, for example when two cubes are touching each other) "Color model for polygon visibility", then "Remove marked polygons" (something like those names). and it doesn't explain what they are unless you read the instructions. Meshlab can do a lot too - normal fixes, holes, zero area polygons, but you fix things by combining the MANY filters and processes in its drop-down menu's. (Bad people use a local copy of Autodesk Netfabb Ultimate from a pirate site, making an account and going online is the legal way to do it)Īlso Meshmixer can fix a few simple problems - (holes and normals are its strong point) (Just make one for the purpose of cleaning and fixing models!) You need to make a free Adobe login to use it. Try putting the model through this site, I've had some very good results with it: They need fixing before bringing the STL into OpenSCAD Like pushing two pieces of paper together they'll look connected, but they aren't.)Īny or all of these issues will kill the build in OpenSCAD. (if two triangles are next to each other, but DON'T connect up to the SAME end points, they'll look joined, but there'll be a zero area hole between them. There is a less verbose yet more complete list of changes on GitHub.īuilds are available for Mac and Windows, there’s a PPA for Ubuntu (not updated yet), and source code is there for everyone (a note to Fedora users: unless you like jumping through hoops before using software, build with Qt4 and the respective version of QScintilla).The model's got problems, definitely one or more of these: 1: HolesĦ: Zero area polygons (2 or more points are in the same place)ħ: Zero area holes. The user interface got a few improvements as well: new startup dialog to quickly open recent files or examples from a library, new QScintilla-based code editor with folding support, SVG and AMF exporting, and more. using PNG as input for a heightmap in the surface function. There are a couple of new functions and some improvements in the existing ones, like e.g. You can control if you want rounding of corners (and by how much), straight corners, or chamfers. One more new OpenSCAD function is offset() which moves polygon outlines outwards or inwards by a given amount. An unparalled imaginative example here is the word “Devanagari” written in, well, Devanagari:įor information about text attributes such as vertical and horizontal alignment have a look at the documentation. The other benefit is that complex scripts are supported. Text("en", size="4", font ="Lobster Two") It’s unlikely that there will be manual kerning, but you can fix your model the old way, by splitting a word into several blocks, then translating them accordingly like this: text("op", size="4", font ="Lobster Two") Of course, if you are going to 3D-print that, you need to merge these ligatures. The command for that is as simple as: text("open", size="4", font ="Lobster Two") A somewhat tired example here is, of course, the much abused Lobster typeface which has quite a lot of these ligatures: What it means is that OpenType features like contextual ligatures are supported. The first intersting new feature in v2015.03 is support for text, especially since OpenSCAD relies on harfbuzz, free/libre OpenType shaping engine. a platform for a micro spider hex multirotor, 3D-printed in PLA from a design available in the OpenSCAD file format on Thingiverse. These days, of course, there is an OpenSCAD workbench in FreeCAD for more visually inclined people. Complex objects are constructed from solid primitives such as cube, sphere, cylinder, polyhedron etc., extruded from 2D objects etc. OpenSCAD is different from the usual solid modeling CAD software in a way that instead of visual modeling you use a simple declarative programming language, hence “The Programmers’ Solid 3D CAD Modeler” slogan. Marius Kintel released a major new version of OpenSCAD, a 3D solid modeling application popular with the makers movement and 3D printing communities.
