Hold down the Shift-key while you rotate to make this more accurate. I wrote a couple of weeks ago about the excitement surrounding Clifford Wolf's new freeware OpenSCAD program.OpenSCAD uses a cool keep-it-super-simple approach to 3D modeling, eliminating the resource-hungry what-you-see-is-what-you-get (WYSIWYG) editing environment favored by most 3D modeling packages, and replacing it with a text-based scripting environment in which models are programmed . There is the option to include axis and perform animations. fred_dot_u. It will be great because being able to get a surface generated from a parametric curve mesh will make for some very . We've seen how to draw a circle in Circle. The children module. However, beyond the obvious graphical VS text interface, there's another significant difference between the two: OpenSCAD's base concept is making operations (add / subtract) on solid primitives (prisms, cylinders, spheres) whereas Fusion360 is based on 2d sketches that you extrude. The surface may be any fragment of a conic (including cylindrical) surface, or any other mathematically defined surface. With the right setup, you can even make adaptable, "parametric" models. I want to be able to create a module which accepts a string then create a 3-D object with that string embedded in the surface as a text.

Following earlier advice by JD Mather I have created an inwards offset surface of 0.5mm and made my solid part invisible whilst executing the function. After about two weeks worth of work, the Bezier Mesh project has finally reached a "1.0" state. While OpenScad is a mathematical language, it doesn't always produce the exact mathematical output. When I pulled the left cylinder upper stick coil the rubber boot came off inside the cylinder. > I will look further into this, as I'm . I used the Mirror modifier to make it symmetrical. While it is possible to hand write both g-code files and STL files, you probably want to work at a higher level again. Helix along curved taper (not sharp edged) Adam. :roll:I am endeavoring to wrap text around a sphere. Inspired by OpenSCAD, ImplicitCAD was originally started by Christopher Olah in early 2012, aiming to create a solid programmatic CAD tool to create complex models for 3D printing. appendPoint([x,y]): create & return a new Path2D containing the callee's points followed by the given point . It makes sense to remove those extra vertices and generate a smoother object. . The way this was done before was make each letter by itself with shapestring, extrude each letter to a solid, place each letter individually into the correct location, then use a Part WB boolean (common is probably best) with a cylinder of the appropriate diameter so that the outer surface of each letter is . There are no true curves in OpenSCAD, so STL output is one to one with the source code and the rendering apart from some numerical truncation to floats. Can openscad bend text (project it on curved surface)? Ah - Try using Smart Duplicate (CMD+D for Mac) to Duplicate a letter, rotate it and repeating to create the curve you want. Since version 2015.03 (March 2015), OpenScad has a text module that can produce 2D text that then can be extruded. Linux AppImage, Windows 32bits or Windows 64bits) Build from sources: see full instructions here, but you'll need . That latter model works very well with a CNC router & plywood.
