CAD Basics: Getting To Know Blocks And Layers
June 12, 2020
Presented by: Jake Lott
The terms "layers" and "blocks" are two basic but crucial foundation points to understand when working in the CAD world. We'll dive into the hows and whys of blocks and layers when it comes to drafting. In developing a better understanding of their importance, you'll gain valuable insights into fundamental concepts such as "defined," "purge," "redefine," and "source," which will in turn build your confidence when navigating through and designing in CAD.

0:00 – 3:20: Intro/TOC
3:21 – 5:49: What is a Layer?
A layer is a way to organize objects in a drawing. (3:21)
Benefits of layers (4:20)
5:50 – 8:14: What is a Block?
A block is a named group of objects that function as one object. (5:50)
Benefits of blocks (7:00)
- Reduce repetitive tasks:
- Changes
- Moving
- Copying
- Deleting
- Improved accuracy
- Quantities
- Style
- Component consistency
- Administration
- Maintain standards
- Reduced file size
8:15 – 25:07: What to Think About When Dealing with Layers and Blocks
Things you should be asking yourself (8:15):
- What are my main points right now?
- What am I trying to achieve with my layers and blocks?
- What is my naming convention going to be?
- Does my standard comply with NCS?
- Can my setup work well with others?
Why is this important? (10:43):
- Organization is key!
- The more you can reduce manual processes, the better change to sustain/maintain your standards.
- Much easier to troubleshoot
- Your final decision will ultimately impact how things function within CAD (and with others' files)
Colors = lineweights (12:23)
A look at our default colors and corresponding lineweights (12:58)
How line colors turn into a black-and-white plot (CTB plot styles) (17:00)
Index colors (colors 1 through 255) (17:45)
Using True Colors (18:15):
- True Colors are set as you create given layers.
- They're used when you need to show a portion of the plan in color while the rest is black and white.
