- Layers in LibreCAD - Part 2
(LibreCAD v2.1.3 librecad.org/ )
This video is the 2nd video in a series about using Layers in LibreCAD. This is part 2 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 RUclipsrs (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 ( help.sketchup.... ) 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 ( www.openoffice... ), a suite of programs similar to Microsoft Office. Blender ( 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 : ImagineThenMAKE@gmail.com . Thanks for watching!

Hello, block from layer X to "layer 0"? Now I know how to do it. People like you contribute to making the internet a beautiful tool. Thank you for the post of this video and for my answer.
You're welcome. I'm glad my video was helpful. Thanks for your comment and for watching.
thanks alot, i wanted to know how to move certain lines to a different layer, it should have been more strait forward.
I agree, it should have been more straight forward. All I can say is that because this program runs on Windows, Mac, and Linux, maybe programming the more straight forward way for Windows users maybe would not have worked for Mac or Linux. I'm not sure, I'm just guessing here. I do know that maintaining 3 different versions of the program for the 3 different OS's would be a royal pain.
The good news is that once you understand how to do it and practice a few times, I don't think it is too bad.
Thanks for your comment and for watching.
I noticed that only when the entity is selected does it become a dashed line indicating selection. Is there a way to setup Librecad so that when the pointer is close to an entity, the entity goes dashed or reacts in some way before clicking select it? This could help in crowded entity situations so that one doesn’t select what they don’t want to select.
Interesting question Mark. I don't think there is a way to do what you'd like. However, maybe separating crowded multiple entities into separate layers would allow you to have better control over what you are selecting. (Just make invisible /turn off the layers that don't contain the entity that you want to select.
Thanks for your question and for watching.
@@ImaginethenMake ok thanks for looking into it
You're welcome Mark.
Hello, I would like to learn how to modify shapes (entities) to exact values. For example, I want to modify a rectangle which is 1.22x2.33 to 1.000x2.000. The manuals don't explain well. Spent 2 hours trying to figure it out.
Thank you
Hi George. There are a couple different ways to do this. Some methods may be more attractive to you then others.
1) You could start a new layer and redraw the rectangle to the correct dimensions. If you snap to the grid this makes the lines spot on (just make sure the grid is set to the proper size). Switch back to the original layer and delete the first triangle. Use the Move/Copy command to move the new triangle to the original layer.
2) You can remain on the current layer and draw the rectangle in a different spot in your drawing. Then delete the original rectangle and move the new one into position (use the Move/Copy command).
3) You can click on each line you want to edit (this selects the line) then left mouse click and drag one of the end points to the new position. If you are snapping to the grid, this makes a very accurate line. You can drag each end point to a new spot until you get what you want.
4) You could draw lines using the Command line (I have some videos that shows how to do this).
The easiest option is probably #3. Please let me know how you make out with a follow-up comment here.
I hope this helps. Thanks for your question and for watching. And be sure to check out my LibreCAD playlist ( ruclips.net/p/PLGCBwUeR2BD2ypYi5k0c4p6M52YO8Z-WD ) to pick up some more tips about using LibreCAD.
