With it you can edit values and other properties of all attributes that are already in a block in a file. Use it to manage attributes in a specific block. BATTMAN has come to my rescue many times in AutoCAD. The response I typically get is, “Really?” It’s true. This is my favorite command to tell people about because they never ever believe me! Never. It will clean up your file be removing duplicate lines and other objects. OVERKILL is what you enter on the command line to start the Delete Duplicates command. OVERKILL is a long time Express Tool that was made a native AutoCAD (and therefore AutoCAD LT) command in AutoCAD 2012. And yes, AutoCAD can handle NURBS!! It’s not just for 2D! Because of their flexibility and accuracy, NURBS models can be used in any process from illustration and animation to manufacturing. Non-Uniform Rational B-Splines, are mathematical representations of 3-D geometry that can accurately describe any shape from a simple 2-D line, circle, arc, or curve to the most complex 3-D organic free-form surface or solid. It stands for “Non-Uniform Rational B-Spline”. Ok, this isn’t so much of a command but an object. The commands are 3DMOVE, 3DROTATE, and 3DSCALE. You can use the system variable DEFAULTGIZMO to set which gizmo you will use. It is really a tool that lets you move, rotate, or scale 3D objects in AutoCAD. GIZMO is not a Mogwai nor is it an actual AutoCAD command. But EATTEXT is much more fun to say than DATAEXTRACTION. EATTEXT used to be the Attribute Extraction wizard but was replaced with the Data Extraction wizard. This command doesn’t really exist in AutoCAD anymore but you can still type it in. AutoCAD will tell you who is holding on to your file. Run the WHOHAS command, browse to the file you want to check and pick it. Have you ever tried to open a file only to be denied! Read only is fine unless you want to actually do some work in the file. This command will tell you “who has” a file open.

Normally you would UNDO the delete but you don’t want to UNDO your work! OOPS and it’s back.

This is nice if you accidently delete something but don’t realize it until you have already done a lot of work. This command will undelete the last object that you deleted. Here is a list of some of those commands and what they do. Sometimes though some commands just tickle the funny bones of other AutoCAD users. Most of them make sense as to what they do with regards to their names. There are a hundreds of command and system variables in AutoCAD.
