AutoCAD layer logic is the foundation of keeping a drawing organized and not wasting time later. In the third lesson of our AutoCAD series, we explain what layers are for, using a finished floor plan. Together, we see why walls, doors and furniture sit in different colors. We also introduce the basic buttons in the layer window one by one.

AutoCAD Layer Logic: Organized Drawing with Layers

We recorded this lesson in 2013 with the AutoCAD Classic workspace. In newer versions, the menus moved to the ribbon. Still, the logic of the Layer Properties window has stayed the same. (The video is in Turkish; this guide walks through the key steps in English.)

In this video

why a plan with layers looks colorful,
the options for turning layers on and off, freezing and locking them,
layer color, linetype and plot settings,
choosing the current layer and drawing on it,
a short introduction to text styles and scale settings.

What is AutoCAD layer logic?

In the plan in the video, the walls are in one color and the doors in another. Furnishings such as tables, armchairs and sofas are in a separate color too. There is a reason for this. Each group of items sits on its own layer. That way, you can hide or show any group with a single click.

If you draw everything on one layer in white, you won’t see a problem at first. But as the drawing grows, things get messy. For example, when you want to copy only the walls to another floor, the furniture gets in the way. In short, drawing without layers makes you do the drawing’s grunt work later.

Keeping layer names organized

As a project goes through revision after revision, layer names get messy too. The file in the video has short names such as “tf1” or “ince 2”. Clear names such as “furniture 1, furniture 2” are easier for everyone to understand. So we recommend setting up a naming system from the start.

AutoCAD layer logic: the window buttons

We open the full layer window from the Format menu with Layer. Don’t be intimidated; the window is actually quite simple. Each row has a layer name with a few icons next to it:

Light bulb: turns the layer on or off.
Freeze: disables the layer on screen and in calculations.
Lock: protects the objects on the layer; you can’t erase or move them.
Color: sets the layer’s color on screen and in print.
Linetype: chooses a continuous (Continuous), dotted or dashed line.
Plot: sets whether the layer is included in the printout.

The Plot setting is especially useful. For example, if you turn off the Plot icon on the door layer, the doors stay on screen but don’t appear in the printout.

Why is AutoCAD layer logic different from Photoshop?

In Photoshop, layers stack on top of each other and their order matters. In AutoCAD, what matters is not the order but the current layer. First you choose which layer you will work on. Then everything you draw goes onto that layer.

We show this live at minute four of the video. When you pick the window layer from the layer list, that layer’s color and linetype appear in the boxes next to it. These boxes show ByLayer. In other words, the object takes its color and linetype from the layer. Then the line we draw with the Line command automatically goes onto the window layer. When we pick the wall layer and draw, the line goes onto the wall layer.

Isolating parts by turning layers off

We see the benefit of this organization right away. When we click the wall layer’s light bulb and then click an empty spot, the walls disappear from the screen. In the same way, we turn off the furniture and the grid axes and leave only the columns. That way, you can easily extract the part of the project you need.

A quick look at text styles and scale settings

At the end of the lesson, we show that you can use more than one font in a project. You also set things up in advance for scales such as 1/50 or 1/20. Scale within scale, such as drawing a 1/5 detail on a 1/50 sheet, is an advanced topic. We cover these in later lessons of the series.

In the next step, we create a layer and make the first drawing; the whole series is on our AutoCAD basics page. For a general overview of the program, read our AutoCAD tutorial article. If you want to set up the same organization in SketchUp, our article on using tags will help. For current version information, see Autodesk’s AutoCAD page.

Summary

AutoCAD layer logic rests on a simple rule: each group of items sits on its own layer. Choose the current layer first, then draw. Manage the layers with the light bulb, freeze, lock and plot buttons. That way, even in large projects, you can separate the part you need in seconds.
