MongoDB Atlas runs apps anywhere
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
...The system emphasizes reproducibility by storing CAD logic as editable code rather than opaque binary files, allowing iterative refinement through agent-driven workflows. It includes a local visualization interface called CAD Explorer for inspecting generated geometry and supports multiple export formats for engineering and manufacturing use. The project also integrates modular “skills” for robotics, motion planning, and manufacturing validation, making it highly extensible. Designed to run locally without backend dependencies, it provides a flexible environment for experimentation and production workflows.
ThanCad is a 2dimensional cad, with limited 3d support and raster inclusion capability and emphasis in engineering. It is being written in Python and since it uses the Tkinter library, it is platform independent.
DSpice: Design and Simulation of Circuits using Spice

MaxFem is an open software package for electromagnetic simulation by using finite element methods. The package can solve problems in electrostatics, direct current, magnetostatics and eddy-currents.
Since version 0.4.0, MaxFEM requires Python 3.
We have moved the installers to the MaxFEM website (see below). In order to improve MaxFEM, we will require you to fill out a simple form before downloading them.
TexGen is a geometric textile modelling software package to be used for obtaining engineering properties of woven textiles and textile composites.

Linux TinyCad, or LiniCad, is a tiny CAD used for educational purposes. It is written in Python/Tk and its goals are to be as programmatically easy and small as possible.
A designer’s program for describing parts of the building
...It reads a text (session) file from which it compiles the information. It then allows the user to browse, analyze and export the resulting building knowledge. The compilation system is written in pure Python. The building components created are rendered in PythonOCC. The GUI is written using PyQt.

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.
CAD Scripts project is designed to automate the work of CAD Softwares. Here you will find scripts/softwares which help to do tasks easily. E.g- Specify coordinates of figures in input file and get output dxf file without actually drawing anything.
A plug-in for Abaqus FEA with empiric data for many types of materials (linear, nonlinear, ortotropic). A simple GUI for creating properties for common materials and sections for bulk and shells.
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
Simple CAM program for creating RS274NGC gcode from vector format files like DXF CF2 PLT. Can be used with AXIS interface from EMC project. It's early alpha stage.
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.
