105. Construction Layer in LibreCAD

Описание: Layers in LibreCAD - Part 7
(LibreCAD v2.1.3 https://librecad.org/ )

This video is the 7th video in a series about using Layers in LibreCAD. This is part 7 of this series and of course I recommend watching all of the parts in order since they all build on each other.

Using Layers in LibreCAD is like creating a drawing on separate sheets of paper and then stacking those separate sheets on top of each other. This is crudely demonstrated in part 1 of this video series.

Once you understand how layers work, you'll find that you can use them in many, many different ways to help you develop your drawing. A few of the ways we can all use layers are demonstrated and discussed in subsequent parts of this video series.

If the viewer is brand new to LibreCAD, I suggest watching an earlier video I created which introduces the new user to LibreCAD and the basics of how to use it. Here's the link:

LibreCAD is a free, open source CAD application that can be run on Windows, Apple, and Linux computers (I am running the Windows version.). There is a lot of free support and program documentation that can be found online. There are also several YouTubers (like me!) that have produced videos about this program and often answer questions from users and viewers.

"Open source" computer programs refers to a group of programs where the "source code" (the part of the computer program that defines and controls how the program actually works) can be studied, modified, experimented with, and shared because its design (the "source code") is publicly accessible. In contrast, commercial software (computer programs where the user must pay $$ for a license allowing them to use the program), typically does not include (or make available to the public) the source code.

Because open source programs have the source code for the program available to the public (for free), the very large, global community of computer programmers have the opportunity to study how the program works and to make changes (hopefully improvements) if desired. This framework for how computer programs can be improved allows for global collaboration and can (but not always) produce a better result (a better program) as compared with programs that are developed only within the confines of a commercial company.

It should also be noted that some commercial software companies do release free versions of their otherwise paid for applications although the source code is NOT released. This allows for the use of the program without the ability to change how it works. As an example, I use SketchUP MAKE 2017 ( https://help.sketchup.com/en/download... ) which is/was downloadable and usable for free.

LibreCAD is just one example of a successful open source program that I use; there are many others. As an example, I also use OpenOffice ( https://www.openoffice.org/ ), a suite of programs similar to Microsoft Office. Blender ( https://www.blender.org/ ) is also another free and open source application that includes everything needed to draw and animate in 3D. (Some users have created their own animated movies using Blender!)

As always, I welcome your comments and questions. If you prefer, you can email me at : [email protected] . Thanks for watching!
