What is HTTP?
Fig. 1 Hypertext Transfer Protocol
HTTP stands for hypertext transfer control and it is a protocol for transferring data between a web client and a web server. Hyper text transfer protocol was invented alongside HTML (Hypertext markup language) to create the first interactive, text-based web browser: the original www or World Wid ...
Hi Guys! Hope you’re well today. I welcome you on board. In this post, I’ll walk you through How to Install PCBWay Plugin for FreeCAD PCB Software.
Before we move further and help you with the installation of the plugin, let’s get a brief introduction to the FreeCAD software.
FreeCAD is a free and open-source parametric 3D modeler used to design real-life objects. With parametric modeling, you can easily modify your design and change its parameters. The tool is mainly used in mechanical engineering for product design and also proves to be handy in electrical engineering for electronic board designs. It supports Windows, Linux and macOS operating systems. Python programming language is primarily used to extend the overall functioning of the software.
