SketchSolve can be used to solve solve geometric constraints problems found in CAD software. This project is one of the first geometric constraints solver intended to be used in open source CAD ... [More] software. Another similar project here on Google code is psketcher. In these problems profiles can be created from primitive objects like points, lines, circles, and arcs. These primitives are subjected to geometric constraints like equal length, concentric arcs and so forth. The solver then solves for a set of primitive parameters that satisfy the sketch constraints. Currently only 2d sketch problems are supported. However I hope to soon also have a set of 3D part Assembly constraints working. This would make SketchSolve be able to solve complex Assemblies. However, I only plan to write that section of the code if people actually use the 2d solver. The solution method used is actually a optimization method. The sum of the constraint violations are the objective of the optimization problem. The optimization routine used is a BFGS update Newtons method. An Optimization routine was selected because there are often more or fewer constraint equations than unknowns. The constraints that are currently supported are the following: pointOnPoint pointToLine pointOnCurve horizontal vertical radiusValue tangentToArc tangentToCircle arcRules Point to point Distance Point to point vertical Distance Point to point horizontal Distance Point to line Distance Point to line vertical Distance Point to line horizontal Distance lineLength equalLegnth arcRadius equalRadiusArcs equalRadiusCircles equalRadiusCircArc concentricArcs concentricCircles concentricCircArc circleRadius angle ( between two lines ) parallel Perpendicular Colinear Lines Point On Circle Point On Arc Point On midpoint of a line Point on midpoint of an arc Point on a quadrant point of a circle +x (parameter = 0) +y (parameter = 1) -x (parameter = 2) -y (parameter = 3) Points Symmetric about a line lines Symmetric about a line Circles Symmetric about a line Arcs Symmetric about a line The constraints that will be implemented soon are the following: others I can't think of right now Let me know if there are constraints that you use that are not on these lists !!!!

A software to generate G-code for laser / plasma cutting with nesting capabilities. Also useful for mill toolpath generation. It can be also used as an Autocad's DXF viewer.

The main goal of this project is a library based on OpenCASCADE and FreeCAD which offers basic CAM algorithms for milling or other machining operations.

SteelCAM is a library for generating toolpaths for use with CNC machines.

A standalone system for generating VoluMill toolpaths

pyturn is a simple python code generation tool made for cnc lathe operations. It produces 'g-code' with xz coordinates. pyturn will not generate drawings or dxf files- these files should be generated ... [More] with some other CAD program (like Qcad). pyturn is meant to be very simple and easy to understand. [Less]

The software includes very simple links or bridges to many other technologies, and applications. Current work of KGraphicControl gives users access to the file types of KPD and KP2 which can be ...

There are currently no svn files... :-( See the Wiki General_Information_links_Index for download links, and release notes. [Less]

Development status: this project has not been updated since 2008, a new C++ version is being planned...This project aims to create an open-source cross-platform program for calculating tool-paths for ... [More] machine tools (eventually, something close to MasterCAM or SurfCAM). Below we will have a blog-style list of screenshots as development progresses: 2008 Mar 20 First tests with Drop-Cutter together with a kd-tree for finding which triangles are under the cutter. 2007 Aug 08Initial tests with Drop-Cutter. Surface-normal data needs to be re-calculated for some strange reason. Only 5% of drop-cutter calls are useful, need a kd-tree search to speed up algorithm. 2007 July 27Rendering of STL files works: 2007 JulyThe first milestone (July-August 2007) for this project is Working OpenGL window with pan,rotate, and zoom (exists but needs work (proportional zooming/panning etc, perspective/ortho views)) STL surface loading (ascii exists and works) Raster-finish toolpath creation using DropCutter algorithm G-code (post-processor needs to be written) All of these components exist (sort of) by themselves so it should not take too long before we have our first rudimentary MonoCAM going!
