Antimony - CAD from a parallel world

Among three-dimensional CAD systems, programs that implement two basic design approaches are most known: direct modeling and parametric. 3r3197.  3r3204. 3r3197.  3r3204. In addition, there are procedural CAD systems that allow modeling through programming. This approach has gained recognition among fans of programming and device design with open source code and design. For example, well-known OpenSCAD, which is mentioned here more than once. 3r3197.  3r3204. 3r3197.  3r3204. I propose to look at another unusual CAD system called Antimony. 3r3197.  3r3204. 3r3197.  3r3204. Antimony - CAD from a parallel world ...

Deliverance from illusions

I have long wanted to find a job related to the development of 3r3r78. CAD [/b] programs. Because it is interesting to me and because I have a lot of experience in this field (20 years). And in 2010 my dream came true and I got even more than I wanted.
And the first time I just fought in ecstasy. Favorite work, the opportunity to work at home. I had ambitious plans! At the very beginning I sketched this plan for myself in writing Cobalt Next Steps.
At the end of last year, Robert Bou, owner of the company
? came to Kiev. Ashlar-Vellum [/b] with wife Julie. And during lunch, I told him that ...

 3r? 3513. 3r3-31. Every year in the field of design automation, parametric three-dimensional CAD systems are increasingly strengthening their positions. The usefulness of this approach in engineering is now beyond doubt, and the scope of application of this approach is extensive. 3r301501.  3r? 3513. Nevertheless, in engineering there is still room for traditional two-dimensional design, and there are appropriate tools for that. 3r301501.  3r? 3513. 3r301501.  3r? 3513.

DDR SDRAM - design features and signal integrity

DDR SDRAM - design features and signal integrity  3r3118.
 3r3118. 3r3111. Designing electronic devices using fast DDR SDRAM memory modules requires special attention to the problem of signal integrity. The article describes the modern modeling tool for solving such problems. 3r33112.
 3r3118. Today, almost all modern electronics are equipped with memory modules. Servers, computers, smartphones, game consoles, GPS-navigators and most other devices are designed based on processors and FPGAs. Such devices require high-speed, high-bandwidth memory or dual frequency data transfer (DDR) memory. With each new generation of DDR SDRAM (synchronous ...

Hot tech support story, or Why does AutoCAD delete proxy objects?

Hot tech support story, or Why does AutoCAD delete proxy objects?  


The purpose of this article is not to discredit the software. The article is purely informational in nature and is intended to protect the end user, who can under certain circumstances lose his data while working in AutoCAD.
GraphiCS - cross-platform application, designed for the development of project documentation, developed by CSoft Development.
nanoCAD SPDS - the same SAPi GraphiCS, but on the platform nanoCAD Plus from the company Nanosoft.

Single-stage gearbox with drive from Stepper Motor

In this post I want to talk about the production using a previously made by me CNC machine with a single-stage straight-through gear.
Single-stage gearbox with drive from Stepper Motor  
gantry CNC machine , about its development and construction on this resource is located my previous article.
Just want to say that this project serves only to gain experience in designing simple gear pairs and their manufacture for possible application in subsequent projects.
Since on the machine tool it was planned to process not only wood and plastics, but also dural, it was interesting to make a gear pair just from this material.
By the availability...

Modeling of the Sagnac effect by the methods of geometric optics

Modeling of the Sagnac effect by the methods of geometric optics
High-precision inertial navigation systems (INS) are one of the most high-tech elements of the modern aerospace and military industry. The task of such systems, built on the basis of accelerometers and optical gyroscopes, is the determination of angular velocities, accelerations of a moving object, and, in general, the orientation of the object in three-dimensional space.
The specific feature of the ANN simulation is that in the modeling domain, both rectilinear and rotational motion often occur, which strongly affects the operation of these systems and, accordingly, requires accounting. In this article we ...

FreeCAD - a new method of drawing

FreeCAD - a new method of drawingDisclamer
: I've never worked with CAD /CAM applications in my life before, and, suddenly, I had to. The principles of the work of FreeCAD have so delighted me that it requires an urgent post on Habr to tell others.
Written in this post, it is likely to be trivial and boring for most active CAD users, and this post is aimed primarily at non-CAD users in order to tell them about the wonderful new world of computer graphics.
I had a simple task - to make a 3D model of my apartment. Not just the "walls in size", but all the beams, ledges and bends. I tried one, the second, the third ...
