By default, PICKADD is set to 2, which means that as you click items the selection set continues to grow. In most cases, the PICKADD variable is changed accidentally either by a crash or when a user inadvertently changes it by clicking on its icon in the Properties dialog. The objects will automatically convert to a polyline and save you the confirmation step. Setting this to 1 will skip over the prompt where AutoCAD asks you if you wish to convert lines, arcs, and splines to polylines. By default, PEDITACCEPT is set to 0, but most users prefer to set this to 1. However, if you need to specify a fuzz distance between objects you will still need the PEDIT command. The JOIN command on the Modify panel now works on lines even if they are not co-linear. In AutoCAD 2012, joining arcs and lines into a polyline is easier than ever. GRIPMULTIFUNCTIONAL can be set to values between 0 and 3, defined below.Ġ – will turn off multi-functional grips altogether.ġ – will allow you to access the grip-goodies by holding down the control key as you click.ģ – the default setting gives you grip menus with or without using the CTRL key. However, if you are working with a large-scale drawing, the pop-up menus that appear as you move your cursor over grips can be distracting. Whether the grid is on or not is saved with the drawing, but whether you are seeing the classic or new type of grid is saved in your computer’s registry.ĪutoCAD 2012 has raised the bar for drafting productivity with multifunctional grips on everything from polylines to dimensions. GRIDSTYLE set to 7 means that you will see dotted grid in model space, the block editor, and layout tabs. GRIDSTYLE can also be set to 2 through 7, which affects in which drawing environments the classic grid will appear. The default value is 0, but changing the GRIDSTYLE to 1 will take the modelspace grid back to the pre-2011 dotted appearance. Many people like to work with the AutoCAD grid on, but find the new engineering paper look makes the polar tracking guidelines difficult to see. If AutoCAD happens to close unexpectedly during the running of the script, the variable does not get reset to the proper position. A script or LISP routine will frequently set this variable to the off position while it runs its course, but will reset it back to on at the end of the process. When this variable is set to 0, or “off,” the dialog box display is suppressed for the Open and Save As commands. Most users who have worked with AutoCAD for any amount of time have needed to reset this registry-stored variable. The following is an alphabetical list of some that I consider to be the most useful. No matter where the front end is, they can be controlled through command-line input.
Others can be found in drawing-specific areas such as the Units dialog or the status bar. Most system variables can be controlled through a user-friendly front-end, such as the Options dialog box. Some system variables are stored with the DWG file, while others are stored to your computer’s registry. System variables are values that control command settings, interface behavior, and user options. In AutoCAD® there’s a hidden treasure trove of options that many users do not realize exist.
