To me, the more difficult adjustment was getting used to using a functional language, which I had never had to do before. ![]() Or at least, English speakers in particular. I think the former is closer to how humans describe things than the latter. The OpenSCAD equivalent to this would be something like “sqrt() sin() x ”, whereas the RPN version might be “x sin sqrt”. I can guess you would probably prefer Reverse Polish Notation, but to those of us who grew up with algebraic expressions, there’s nothing backward about saying “sqrt(sin(x))”. There is nothing in “reverse” about OpenSCAD’s notation. Same goes for fillets, but that’s a much simpler problem. Luckily, OpenSCAD is both open-source and local to your machine, so it’s possible to add things like this to it, if you have or can find someone else who has the time and skills. Or this could be done independently, with a script that reads an IGES file and writes a. I’m sure that the OpenSCAD developers would be happy to have someone add STEP import. Which basically means, easy to export, hard to import. Each part has its own scope and introduction.” This makes STEP the biggest standard within ISO. To quote the Wikipedia article, “In total STEP consists of several hundred parts and every year new parts are added or new revisions of older parts are released. STEP, by the way, is a complete nightmare, so the notion of “reasonable STEP output” is a kind of fantasy/illusion/delusion. Exporting to graphics primitives appropriate for STEP would take considerable work, especially where you have things like hull() and minkowski(), which are much, MUCH easier to produce as polygons than as graphics primitives or B-spline surfaces. In its present form, OpenSCAD is essentially a rendering engine that operates from a text-based database that is produced in a text editor window. That would require a whole lot rethinking of OpenSCAD. Posted in 3d Printer hacks, Software Development Tagged 3d, cad, CascadeStudio, modeling, openscad, parametric, parametric design, programming, text-based modeling Post navigation We’ve seen this parametric workhorse tackle everyday tasks like container boxes to high-security keys. Please tell us what you think of CascadeStudio below, and if this changed your mind about text-based modeling. You can save and load JSON files if you prefer to download your files, and you can export STEP, STL, and OBJ files for your printer. Each time you refresh the rendered model by pressing F5, the URL updates, so it is possible to create dated savepoints with your browser bookmarks. ![]() You cannot simultaneously edit like a Google document, but it is conceivable to store a 3D model within a QR code, or an RFID tag, possibly without a URL shortener. In our opinion, the biggest boon to CascadeStudio is that you can send someone a URL, and they will get access to a fully-functional copy. Minor differences of this scale mean that anyone familiar with one may have speedbumps with the other, but not roadblocks. You may also notice the capital letters for CascadeStudio. A cone in OpenSCAD uses the cylinder() function while CascadeStudio insists that Cylinders() are the same diameter at the top and bottom, but a Cone() tapers. For starters, tooltips reveal that formatting is a little different. We’re going to assume that anyone reading past this point is familiar with this type of modeling.Īt the first keystroke, it is evident that CascadeStudio is different from OpenSCAD. His project CascadeStudio has a GitHub repo and a live link so you can start tinkering in a new window straight away. appreciates the idea but wants to see something more robust, and he wants to see it in your browser. Some people adore the text-only modeling language, and some people abhor the minimal function list. The lightweight program takes megabytes of space, not gigabytes, so many people have a copy, even if they’ve never written a shape. Strong opinions exist on both sides about OpenSCAD.
