FreeCAD is a general purpose parametric 3D modeler.
FreeCAD is aimed directly at mechanical engineering and product
design but also fits in a wider range of uses around engineering,
such as architecture or other engineering specialties.
FreeCAD features tools similar to Catia, SolidWorks or Solid Edge,
and therefore also falls into the category of MCAD, PLM, CAx and
CAE. It is a feature based parametric modeler with a modular software
architecture which makes it easy to provide additional functionality
without modifying the core system.
FreeCAD is under heavy development and might not be
ready for production use.
Alliance is a complete set of free CAD tools and portable libraries
for VLSI design. It includes a VHDL compiler and simulator, logic
synthesis tools, and automatic place and route tools. A complete set
of portable CMOS libraries is provided. Alliance is the result of a
twelve year effort spent at ASIM department of LIP6 laboratory of
the Pierre et Marie Curie University (Paris VI, France).
LeoCAD is a CAD program that can be used to create virtual LEGO models.
It has an easy to use interface and currently features over 4000 different
pieces created by the LDraw community.
Electric is a sophisticated electrical CAD system that can handle
many forms of circuit design, including:
- Custom IC layout (ASICs)
- Schematic drawing
- Hardware description language specifications
For real functionality, one should consider installing
support simulation software such as cad/spice.
BrickUtils is a simple utility for builders that use LEGO Digital Designer
or LDraw-compatible CAD for designing models.
IRSIM is an event-driven logic-level simulator for MOS circuits.
To run irsim, users should set CAD_HOME to the base installation directory
where magic was installed, e.g. /usr/local. Alternatively, the system
administrator can create a dummy user named 'cad' with its home
directory set to the installation directory.
Magic is an interactive editor for VLSI layouts that runs under BSD.
To run magic, users should set CAD_HOME to the base installation directory
where magic was installed, e.g. /usr/local. Alternatively, the system
administrator can create a dummy user named 'cad' with its home
directory set to the installation directory.
This is a port of wmping which is a Windowmaker dock app which
is simple usefull program that allows to check host status in your
network environment. It can be used for monitoring servers in the network.
Gdspy is a Python module for creating GDSII stream files, usually CAD
layouts. It includes a layout viewer for the geometries created, and
it can also be used to import and merge GDSII files.
LDraw is an open standard for LEGO CAD programs that allow the user to create
virtual LEGO models and scenes. You can use it to document models you have
physically built, create building instructions just like LEGO, render 3D photo
realistic images of your virtual models and even make animations.
The possibilities are endless. Unlike real LEGO bricks where you are limited by
the number of parts and colors, in LDraw nothing is impossible.
