AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a CAD data file format, developed by Autodesk as their solution for enabling data interoperability between AutoCAD and other programs. DXF was originally introduced in December 1982 as part of AutoCAD 1.0, and was intended to provide an exact representation of the data in the AutoCAD native file format, DWG … [Read more...] about AutoCAD DXF

AutoCAD is a suite of popular CAD software products for 2- and 3-dimensional design and drafting, developed and sold by Autodesk. The AutoCAD family of products, taken as a whole, are the most widely used CAD software in the world.DescriptionInitially a general-purpose 2D drafting program, AutoCAD has evolved into a family of products which provide a platform for 2D and 3D … [Read more...] about AutoCAD
Understanding Vectors – Part 2
Written by MickD www.dcservices.net.auIn the last article we discussed basically what a Vector was and had a brief look at the difference between a Point and a Vector. This time we are going to look at what a Vector is made of and try to really get an understanding of why they are so useful as opposed to a Point. Again, not much math just trying to make the concept … [Read more...] about Understanding Vectors – Part 2
Understanding Vectors
Written by MickD www.dcservices.net.auVectors are very important to understand if you want to use them in your daily manipulations of computer graphics. They are one of the most fundamental building blocks of computational geometry and this will be the first of a few short articles about vectors where I will try to explain them in easy to understand terms. The articles will be … [Read more...] about Understanding Vectors
Seeing a Rotation Matrix
Written by MickD www.dcservices.net.auOne of the hardest things I found when learning about geometry and computer graphics was how to 'see' a rotation matrix and how they are used, they are a handy thing to have and understand in your programming toolkit for AutoCad also. I won't delve to deep into matrices or calculations, what I hope to achieve in this article is to … [Read more...] about Seeing a Rotation Matrix
