If your delete key stops working in AutoCAD, check the value of PICKFIRST. Make sure it is set to 1.
When PICKFIRST is set to 0, selected items are ignored when you launch a command. This does not really have anything to do specifically with the delete key, but this is one of the most reported symptoms.
The value of this system variable is saved in the registry so you should only have to set it once. The GUI for changing this variable is in Options, on the Selection tab, under Selection Modes, and is named Noun/Verb selection. When this toggle is checked, PICKFIRST = 1.
Do you get annoyed at AutoCAD when those little blue boxes that appear on objects and quickly start mashing the ESC key? Are these blue boxes, better known as Grips, just in your way? Let’s take a look at Grips and how you might use them to your advantage instead of causing you grief.
Grips allow you to perform many tasks in fewer steps than you may realize. The most common editing commands are built into grips for all entities, including Stretch, Move, Rotate, Scale, and Mirror. Multifunctional grips offer even more editing commands that vary depending on the object type.
Grips are located at strategic points which also vary depending on the object. So think about this for a second; you select an object and a key point on that object is already selected. You have done two things with one pick, this is what makes pre-selecting objects so powerful. Now what exactly can you do with Grips? Let’s take a look. Read more about AutoCAD Grips 101
A few years ago, we posted some info and sample code on how to create a table in AutoCAD using autolisp. That works OK, but what if you want to define a particular table style first? I ran across this post by Lee Ambrosius on creating a table style from scratch using autolisp.
Autodesk is conducting a survey to gather feedback on AutoCAD HELP. A lot of people did not like the change to primarily online help, now is your chance to tell them. There are also questions on what kind of content you would like to see in HELP.
