It's old news to many of you by now, but I'm still pretty excited about receiving the Autodesk University Speaker Award for Hands-On Labs. My seminar, ‘Click My Ride: Customizing Autodesk® AutoCAD® for How You Work’, received the highest feedback rating among all the labs at AU. With over 700 seminars and labs, the competition was pretty substantial, so this award—for me—is the top of the heap. So however you may want to look at it, I guess I'm out standing in my field.
To continue with that ‘Click My Ride’ theme, in this (now bi-monthly) column, I want to take a look at a couple automation tools, as well as some of the things that we go back and forth with in our daily AutoCAD activities.
…Running a script from the Quick Access Toolbar
…Useful routines for the ACADDOC.LSP file
…Layer column arrangement options
…The fundamental power of Layer Previous
Hope this finds you all well on your way to a productive and prosperous 2014, and keep up the good work!
Layer Walk  is one of my favorites and one that I promote in virtually all my training sessions.
When using Layer Walk, you can select more than one layer using the Ctrl key for random selections, the Shift key for a range, or you can simply click and drag your cursor across the layers you want to select.
But if you have a long list of layers, it's easy to forget the layers you may have selected already, so use Hold Selection!
Open the drawing db_samp.DWG [C:\Program Files\Autodesk\AutoCAD 20xx\Sample\Database Connectivity]
Launch Layer Walk. The layers that are not highlighted (white) are either Off or Frozen.
Make the dialog box as shallow as possible, then select the layers shown in the figure.
After selecting the layers, right-click, then click Hold Selection. An asterisk will appear beside the selected layers.
Scroll down and select the layers named GRIDLN and GRID-08. To view the content of both layers, you will need to use Ctrl… which brings us to the point.
When selecting those two additional layers, the original selection set is still displayed. Had you not used the Hold Selection feature, only the GRIDxx layers would be displayed.
Hold the GRIDxx layers, then turn on E-F-STAIR and E-F-COLUMN.
Before you click OK, be sure to clear the checkbox for Restore on Exit.
Hopefully you see where Hold Selection can give you a bit more control over layer visibility and selection when using Layer Walk!
