LibreCad - CAD for 2D drawing and design. Allows you to solve 2D design problems, such as preparing engineering and construction drawings, such as building plans, interior plans, machine parts or diagrams and diagrams.

Эта игра предназначена для детей в возрасте от 3 лет. Отличается возможностью добавлять собственные изображения

qCAD is a professional CAD system, similar to AutoCAD, designed for creating mechanical engineering drawings and architectural plans. You can create technical drawings such as building plans, interior plans, mechanical plans, or schematics.
You can also easily create and edit drawings with ISO templates and save files in DXF format. The DXF format is used by many CAD systems.

Griffon IDE - это интегрированная среда (IDE) для HTML, Bash, Perl, PHP, C и т.д.

Позволяет генерировать исходный код в несколько кликов, избегая ловушек. Имеет автодополнения, встроенный терминал, управление проектом на C, автоматическую замену текста.

IDLE is an Integrated Development Environment for Python.
IDLE is written using Tkinter and is therefore available on different operating systems.

FreeCAD is an extensible CAD/CAM system that includes some key concepts such as macro recording, workspaces, the ability to run as a server, and dynamically loaded application extensions.

FreeCAD can import and display CAD models in IGES, STEP and BRep formats, as well as meshes in STL, BMS, AST and Wavefront OBJ formats.

SimulIDE is a simple electronic circuit simulator. It allows you to interactively simulate analog and digital circuits, as well as work with microcontrollers. It includes a variety of ready-made components and a built-in code editor.

It supports PIC, AVR, Arduino, and other microcontrollers and microprocessors.

Features:

Gramps is a program for genealogical research. It is an extremely flexible program that meets the needs of both the amateur genealogist and the serious genealogical researcher. Allows you to store, edit, and research genealogical data.
Has the ability to import GEDCOM files exported from many proprietary genealogy programs and can generate a large number of reports in many popular formats. This allows any piece of information to be entered directly into Gramps and any event to be manipulated across the entire database (in any order), helping the user research, analyze and find connections with the ability to fill gaps in relationships.

BRL-CAD is a powerful cross-platform Open Source combinatorial Constructive Solid Geometry (CSG) solid modeling system that includes interactive 3D solid geometry editing, high-performance ray-tracing support for rendering and geometric analysis, network-distributed framebuffer support, image and signal-processing tools, path-tracing and photon mapping support for realistic image synthesis, a system performance analysis benchmark suite, an embedded scripting interface, and libraries for robust high-performance geometric representation and analysis.
