This is an official mirror of FreeCAD. Code and release files are primarily hosted on https://github.com/FreeCAD/FreeCAD and mirrored here. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization. FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.

DXF2GCODE is a tool for converting 2D (dxf, pdf, ps) drawings to CNC machine compatible GCode. Windows, Linux, and Mac support by using python scripting language.

A Windows only 2.5D CAD CAM application. The user experience tightly integrates the CAM aspects when doing design and layout. The target users will layout their design and then immediately generate CNC code. The goal is a design application closer to Adobe Illustrator than to AutoCAD. The user specifies machining aspects during object creation so that when the design/layout phase is completed the toolpath generation can occur automatically. What is 2.5D? Objects created are flat (2D) but have a depth component. So you can create a square that will be machined at a specific depth but the depth will be constant accross the square. It is not/does not: A general purpose CAD (AutoCAD) type program. Support reference dimension on the drawing. Export or import major CAD file formats.

Fachwerk calculates strut-and-tie models used by structural engineers for analysing and designing reinforced concrete structures. The program only uses the equilibrium conditions, thus it is not assuming elastic behaviour.

This Application assists the usage for CNC threading, especially the Mach3 software. The threading cycle uses the G76 command with some parameters. This program lets the user select from hundreds of predefined or free definable thread standards and calculates the parameters for the Mach3 command line. So, essentially just select your thread, calculate it, copy & paste the result to a GCode file, hit "Cycle start" and you get exactly what you want. Also included is a little tool to calculate the pitch diameter of a thread based on a measurement with three wires. Supports the threading standards M, G, R, BSW, BSF, UNC, UNF, UNEF and tapered Pipe R/Rc and Metrical threads. New: NPSM, NPT, NPTF, NPSC, NPSF. Includes an improved version of the Mach3 M1076.m1s threading macro and a matching screenset. Try also the Feed Calculator: www.sourceforge.net/p/feedcalculator

Fachwerk3D calculates three-dimensional strut-and-tie models used by structural engineers for analysing and designing reinforced concrete structures. The program only uses the equilibrium conditions, thus it is not assuming elastic behaviour.

The Feed Calculator is a small program to calculate the feed and spindle speed for turning and milling machines.. The help provides an excerpt of the machining tables which propose cutting speeds and feed per edges for various tools, especially for small machines and modeling. With this data, you can easily find the working parameters for your job on numeric controlled machines. For easier use, you can customize the tool table (number of edges) to your own tool rack.

ZWCAD / AutoCAD Addon für Architektur-gerechte Bemaßungen (automatisches Hochstellen von Ziffern). Durch ArchiDim können nun Architekten, Bauplaner und andere normengerechte Zeichnungen bzw. Bemaßungen erstellen. Die sehr aufwändige händische Nachbearbeitungen aller Bemaßungen, um Endziffern normgerecht hochzustellen, entfällt nunmehr. ArchiDim bietet individuelle Einstellmöglichkeiten für die unterschiedlichen Bemaßungsarten und ist sehr einfach zu bedienen. ArchiDim ist getestet mit ZWCAD+ 2014. Bei Fragen zu ZWCAD+ oder ArchiDim wenden Sie sich bitte an: Michael Wannke http://www.zwcad-kaufen.de info@zwcad-kaufen.de ----------- DEAR ENGLISH-SPEAKERS: IF YOU ARE INTERESTED IN AN ENGLISH VERSION PLEASE CONTACT ME (info@zwcad-kaufen.de) In architectural design the mm-digit in dimensions is usually superscripted. Standard AutoCAD / ZWCAD does not support this automatically, so I developed ArchiDim to conveniently automatize this

A SolidWorks addIn to record dimension values and point positions during movement of a sketch or assembly.

A tool for CNC toolpath generation. Model data in, G-Codes out. The system is kept as generic as possible. Machines with up to 9 axis can be defined. Machine simulator included.

QCAD is an application for computer aided drafting (CAD) in two dimensions (2D). With QCAD you can create technical drawings such as plans for buildings, interiors, mechanical parts or schematics and diagrams. QCAD works on Windows, Mac OS X and many Linux and Unix Systems.

The BladeDesigner package is a CAD/CAE tool providing classes for turbomachine blade design. So far it is optimized to be useful in the aerodynamic design process. It comes with a GUI but is most powerful with user defined python scripts.

new 3d markup language for creating one tool for all 3d CAD data in the world.it is for viewing 3d data without plugins on web and desktop and for creating 3d pdf in one step.

A small program for quickly generation of g-code. It can generate circular pockets, square pockets, etc. Now it can generate program from DXF. You can support a development with donation on my paypal page www.paypal.me/alexdevisa Небольшая программа для генерации G-кода. Может генерировать различные карманы, а так же поддерживает генерацию G-кода из файла DXF. Поддержать проект можно пожертвованием любой суммы на моей странице paypal - www.paypal.me/alexdevisa
