autocad lisp get variable from clipboard

To test, call this and select a viewport border when prompted. Just pass the entity name of the viewport to the function and it'll return the scale factor. A new copy overwrite the last one except that sometimes it does not.When you copy AutoCAD geometry to the clipboard, not only is the data written out to a DWG file, but a piece of data is also added to the Windows clipboard so that when you go to paste this data, AutoCAD will know which DWG file to grab and insert for you. It is a good idea to follow proper programming protocol and reset any variables you change in your program.This will do it. A code coverage tool produces a visual output that allows to see what parts of our code were tested or not: Such capabilities are included into Lisp.You can set most system variables to a new value with the setvar function (some system variables are read-only and cannot be changed with setvar). You can retrieve the current value of any system variable with the getvar function.

AutoCad Viewport Scale And Annotative Text. AutoLISP has two functions devoted to retrieving and setting system variables: getvar and setvar. You can find this in the Markups List in the bottom panel.

A list of AutoCAD system variables can be found in the Command Reference section of AutoCAD’s on-line help.Ĭommand: (setq SNAP_ANGLE (getvar “snapang”)) Hey guys i thought i had seen a lisp which would do this a long time ago but now that i need it I cant find it. Repeat the steps to point to multiple If youve ever used AutoCAD, you might be familiar with.

Both of these functions return the value of the variable name.

The new value is an AutoLISP expression that evaluates to an appropriate value.

(setvar) allows you to change the value of any non-read-only system variable:

You should store the system variable information in a (setq).

(getvar) reads the value of any AutoCAD system variable: ( getvar variable_name) value of the variable clipboard is a tree containing the entire stack of lisp. In AutoLISP, the user can read the value of any AutoCAD system variable using the (getvar) function, and can set any non-read-only system variable using the (setvar) function. The IDEs cut, copy, and paste commands always use the lisp clipboard. In the address bar, type intemp and press enter. You may still be able to retrieve the AutoCAD entities by finding the.DWG file that AutoCAD created. AutoCAD’s SETVAR function, when used in conjunction with a system variable name, will display the current value and permit the user to input a new value. Maybe you cut or copied something to the clipboard and then subsequently copied something else to the clipboard.
