Design your own pottery for 3D printing in full color
PotterDraw is a free 3D software application for designing and visualizing pottery. It’s useful for creating cylindrical shapes such as pots, flasks, vases, bowls, plates, cups, glasses, goblets, or anything similar. The outer wall of the pot is drawn using a spline, which consists of one or more curved or linear segments. The inner wall is generated automatically. PotterDraw can export files suitable for 3D printing. It can also map synthesized or user-specified textures onto the pot. Mesh and texture properties can be modulated by oscillators for more complex effects, and the modulations can be animated to create videos.

Packing two dimensional rectangular elements at orthogonal table
Program was created for optimized packing of two dimensional rectangular elements at orthogonal table with main purpose of printing cutting sheets that can be used for cutting material at production in wood and panel furniture manufacturing. It is developed upon authors several years of expirience at woodworking, and actual carpenters needs when such software is in question. Inspite its look it is fully functional peace of software , with all necessary elements needed for generating cutting sheets. GUI is simple and it consists of fields for entering table and element dimensions on the right, packing, optimization, cutting and cleaning table edges options section bottom left and statistic section bottom right. Upper left are table description field and cut sheet drawing at the center. Right click at the cut sheet drawing and there are printing options. NOTICE : This program was not created for sellers of chipboards and other board materials. All the best, Author

OpenNum lets you distribute solvers with a nice graphical interface
Typically, to program a GUI is time consuming and requires experience with graphic libraries. OpenNum lets you create a graphical interface adapted to your solvers by simply editing an XML configuration file. More specifically, OpenNum lets you · to collect a hierarchical dataset, · to call any executable file and · to visualize scalar and vector fields, plot graphs or show simple plain text files. It also has other useful utilities specifically designed for numerical simulation packages: · it allows managing a centralized materials dataset; · it can read several finite element mesh formats and several field formats.

Helps with the Mach3 CNC Threading functionality
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

A canvas library for generating technical drawings
The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a GObject-based library where a custom application can put common CAD entities such as paths, hatches and dimensions, to automatically create technical drawings. A demo application is provided in order to show the capabilities of the canvas. Although it is possible to interact with the library directly in C (that is what the adg-demo program is doing), the canvas is expected to be used from higher level languages, much in the same way as what done in the GNOME stack. Lua bindings based on LGI are already provided out of the box. The adg-lua project, downloadable from the "Files" section, provides Lua programs and demos that leverages these bindings.

Secondary glazing for sash windows
Application for generating CAD scripts for drawing Glass Shutters for sash windows. Glass Shutters may be used as an alternative to double glazing where it is required to preserve the appearance of your traditional sash windows. The glass is toughened and has a coating which reflects heat back into the room while still letting in heat from the sun. The frameless panels are easily opened to allow access to the window. By choosing an appropriate style, the panel divisions can be made to coincide with the glazing bars. This minimizes the visual impact of the panels from inside while making them virtually invisible from the outside.
Simple Road Planning and Design
Lima VVA is a lightweight Windows application for the planning and design of small to medium road projects. The user is able to design the road interactively while the geometry and earthwork quantities are automatically updated with every change. The program produces high quality drawings, reports, and construction data for the road design. These results can be exported to other systems such as office, CAD and GIS software, surveying equipment, and systems for automated machine control.
