AutoCAD Productivity

Layer Previous

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

AutoCAD Alias Editor

AutoCAD Alias EditorIf you're new to AutoCAD or even if you're not and you find it difficult to remember all the keyboard shortcuts to your favourite commands like L for Line and C for Circle or even 3DO for 3DOrbit, then you need to know about the AutoCAD Alias Editor.

Enter ALIASEDIT at the command line and AutoCAD will launch a tiny application window that lists all the shortcuts in alphabetical order. As this is a seperate application, you can keep it minimised on your taskbar until you need it for reference.

Essentially, this editor simply lists the contents of the acad.pgp file where all the command aliases are stored. Those of you who are a bit more adventurous, may even like to use the Alias Editor to create your own aliases or edit existing ones.
