AutoCAD Productivity

Layer Previous

by Michael Beall

From: AutoCAD Productivity Articles #132
Originally published: February 2014

PreviousLayers are the lifeblood in AutoCAD, and efficient management thereof is the key to your own quality of life; specifically, your sanity.

The Layer Previous button can be a real time saver and is, at its core, a Layer-specific ‘Undo’.

How to Use Layer Previous

  1. Open a drawing, then make a new layer [MC_FEB2014], give it a color and make it current; this will be our testing layer.

  2. Change the Color of any other layer in the current drawing, but don't make that layer current.

  3. On our test layer, draw a small rectangle somewhere.

  4. Click Layer Previous and the rectangle remains, but the color of the layer you changed is restored.

  5. Freeze several existing layers, then Rotate the rectangle.

  6. Click Layer Previous and the previously frozen layers are thawed… but the rectangle is still rotated!

Tip of the Day

Layer States and Viewports

Did you know that Layer States can be saved and used to control visibility of layers per viewport? If you create and save a couple of layer states within an active viewport, you can then toggle them back and forth without affecting any other viewports, or model space. The changes only occur within the active viewport.

Try this:

Create a bunch of random objects in model space on different layers. Now switch to paper space and create two viewports so that you can see all the model space objects in both viewports. Now activate one of the viewports and open the Express Tools LMAN layer states manager. Create and save a new layer state. Now close LMAN and freeze some of the objects within the viewport. Open LMAN back up and create another new layer state. All of this must be done within the active viewport. You can now toggle back and forth between the two layer states within the active viewport without affecting model space or any other viewports. You can also switch to another viewport and use the same layer states on it, or create new ones.
