Open Source Java CAD Software for Mac

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.

Soil Sieve Test Analyzer is an application for analyzing results of sieve test. Sieve Test is part of Grading Test in Geotechnical Engineering that is part of Civil Engineering to classify mechanical soil behavior.

Line-drawing and polygon-filling rasterization algorithms in Java. Simple 2D package and more complex 3D package with Z-buffering. Texture mapping not supported at the moment. Color interpolation for lines, Gouraud shading for polygons fully supported. Floating point vertex coordinates, not integer. Pixel-level aliasing, not endpoint aliasing. Doesn't use Bresenham line style! Works with all Java versions. No external dependencies. Suitable for study in academic institutions, especially as related to line-drawing accuracy. Particular attention to detail concerning chopping of accumulation errors, using a cast from 64 bit to 32 bit strategy, in the interval [1.0,2.0). Individual pixel errors with overlapping polygons or line segments are about one in a billion, but I can't reproduce any errors at the moment by using random number generation with tens of millions of cases. Emphasis not only on correctness, but also on performance for real-world use or hardware implementation.

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.

GeomSS is a geometry modeling and scripting system in Java. Write scripts that create and analyze complex geometry including NURBS curves and surfaces. This is especially useful for tasks that must be repeated with small or parametric variations.

COPanno is now at http://download.tuxfamily.org/copanno/ COPanno is a small utility to find the best solution for cutting rectangular panels in a defined-size sheet. * v1.2 Introduce multi-threading (calculation is up to 8 times faster) and internationalization support. English and French translations are done. * v1.3 Add per panel orientation keeping Copanno est un utilitaire de calepinage donnant la meilleure manière de découper des panneaux rectangulaire dans une feuille de dimension définie. * v1.2 Le calcul parallèle permet d'accélérer le traitement sur les ordinateurs multi-cœurs. La traduction en Français et en Anglais est réalisée. * v1.3 La conservation de l'orientation des panneaux (le fil) peut être définie pour chaque élément.

Open channels hydraulics is very important part of hydraulic and civil engineering. Finding critical depth in open channel flows is a basic task in this field. This is an application for calculating critical depth in open channels flow.

Library to manage DXF file Format.

The PARSEC CEE is the primary achievement of several years of effort at NASA's Marshall Space Flight Center. The CEE was developed to allow engineers in the Advanced Concepts Department to rapidly prototype launch vehicle and spacecraft concepts.

VRforCAD developed in Java and Java3D API, combines two systems: Computer-aided design (CAD) system and Virtual Reality system with its special equipments for visualization and manipulation. See more at: http://www.vrforcad.org

Software application, firmware and U.I. for 4-motors 3-axis milling machine, open hardware, software and mechanics. See also project in details for schematics and images on http://www.contesti.eu/opensource/xyz-dc-motor-controller

Java application for virtual tool shop simulation. Application allows simulation of exchange jobs between some tool shops. Jobs are grouped in projects and are organized in Petri nets (sequences of activities and stores).

Clothes - sewing CAD for creation of models of clothes. Based on the new concept of the automated designing of clothes with use of parametrical model. Creates a base design of model of clothes and allows to change it depending on necessity of updating.
