Beginning with AutoCAD 2014 SP1 (and presumably in future later versions), drawings "infected" with the educational plot stamp will no longer plot the EDU stamp and you will not be warned about the stamp when opening the drawing.
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.
If you need to import a KML/KMZ file into Civil 3D or Map 3D, you can do it using a free download from SL-King Spatial Solutions. Be sure to read the readme file because the install does require you to copy some files and edit an existing file.
The goal here is to produce a cut and fill map similar to what is shown above, where:
The positive and negative values are different colors
The positive values include a leading "+" sign
The negative values include a leading "-" sign
The inherit problem is that you want to place a single label and have it display the proper sign and be in the proper color. If you do not require the "+" sign, then you can do this in a different (and less complex) way. So back to our goal stated above. I have seen various ways of doing this, and this is probably a combination of a few of them as far as I can tell. Read more about Cut and Fill color map in Civil 3D
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
Many of you know we are a huge advocate of using Process Monitor to watch file and registry activity when you detect a slow down problem in an application. We ran across a case recently where the AutoCAD cursor was very "sticky" feeling as the user moved it around on the screen. Closer inspection revealed that the cursor would pause for a moment whenever it passed over an entity. We tried a new empty, no template drawing and constructed a single line. Same problem existed, so we were pretty confident this was not a drawing problem, but rather a application problem. You can imagine the frustration when working in a busy drawing where just about any movement of the cursor resulting in it passing over some entity.
In this case using Process Monitor, we were able to see that AutoCAD was looking for a particular CUIX (menu) file, every single time the cursor passed over an object, over and over and over. Why was it looking for this particular menu file? Who knows? I suspect that whenever the AutoCAD cursor passes over an object in a drawing, it is looking for information about that entity. Whatever the reason, the saved path to this particular menu file was on a slow secondary hard drive and the delay was especially noticeable. Read more about Unresolved partial menus in AutoCAD
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.
