![]() In addition to 2D paths for extrusion it is also possible to read design parametes from DXF files. As data exchange format format for this 2D outlines Autocad DXF files are used. OpenSCAD provides two main modelling techniques: First there is constructive solid geometry (aka CSG) and second there is extrusion of 2D outlines. This gives you (the designer) full control over the modelling process and enables you to easily change any step in the modelling process or make designes that are defined by configurable parameters. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file (see examples below). Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies. Unlike most free software for creating 3D models (such as the famous application Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. It is free software and available for Linux/UNIX, MS Windows and Apples OS X. "OpenSCAD is a software for creating solid 3D CAD objects. HeeksCAD has been built for Windows, Ubuntu, Debian, and OpenSUSE." There are currently English, German, and Itallian translations. HeeksCAD can be translated into any language. See here for instruction how to use HeeksCAD Use the geometric constraints solver to create accurate drawings from rough sketches. Import and export dxf files lines, arcs, ellipses, splines and polylines are supported. Modify solids using blending, or boolean operations. Create new primitive solids, or make solids by extruding a sketch or by making a lofted solid between sketches. Draw construction geometry and lines and arcs. HeeksCAD is a free, open source, CAD application written by me, Dan Heeks, Anyone can download it from įunctionality: Import solid models from STEP and IGES files. Solid modeling exists, open design must depend on translation tools using prescribed Until a standard file format or Open Source OpenCascade ( ) is a project to develop a solid modeling kernel.Īn open source solid modeling kernel might establish a standard file format that can beĮxchanged in collaborative open design projects. Software does not exist at this time, but there may be light at the end of the tunnel. Unfortunately, Open Source solid modeling ↳ QCAD 2.1/2.CAD packages already under development, QCAD ( ) and FreeDraft.↳ QCAD 2.1/2.2 Troubleshooting and Problems.↳ QCAD 2.1/2.2 Suggestions and Feedback.↳ QCAD - Eine Einführung in computerunterstütztes Zeichnen (CAD).↳ QCAD - Una Introducción al Diseño Asistido por Ordenador.↳ QCAD - An Introduction to Computer-Aided Design.↳ Finished 'Ready to go' Scripts/Plug-in's.↳ QCAD 'Script Add-On & Plug-in challenge' - Work in Progress.↳ QCAD Programming, Script Programming and Contributing.I'm sure they would be extremely grateful for any insight/feedback you could provide as someone with great experience in this area, and being pretty much the exact person they are hoping is their userbase :-) Have you looked into libreDWG yet? I have found the responsiveness of the authors to be remarkable and they are eager to have test cases that don't yet work right. Having no access to the ODA libs I have no way of knowing. I don't know if it is easy to keep this option of using the alternative library open or if that introduces complexity to the codebase that you don't wish to support? Hopefully the API of the two libraries is not too dissimilar. ![]() However for the free version it would be much better to use the libreDWG libraries even if they aren't quite as good yet, as then QCAD remains free software that can be built and run on all architectures, and distributed by Debian and its derivatives. I assume they are rather more mature than libreDWG is? Now you have a business to run and having taken out an ODA licence I guess using those libraries makes sense for you. ![]() If QCAD uses these libraries then it will cease to be freely redistributable in Debian, as it would then depend on non-free software. This doesn't help write free software CAD applications at all. As a Linux user I can read the spec or download a windows utility. However the Open Design Alliance libraries are not freely redistributable, (unless the licencing has changed recently), nor are the libraries themselves available for download for individuals. OK, glad to hear that there is progress on this as not having DWG access is pretty limiting these days, as I'm sure you are aware.
