#AUTOCAD LISP USING ENTLAST IN A COMMAND HOW TO#

Hint : Have you ever wondered how to make an AutoLisp routine Auto-Repeat Enclose. If you know the number of times you want to loop, use (repeat), a much simpler command than (while). The next step is to edit out what you donвЂ™t need. Have look at this example : (defun c:loop3 () (setq count 0) (while (< count 10) (princ count) (setq count (1+ count)) ) (princ) ) You should get : 012345678910. Copy the commands from the AutoCAD text window, and paste them into your notepad file.

Performs the TRIM command by selecting the el object (the line) and by selecting the point specified by pt. The next step is to open a new blank notepad file (Please donвЂ™t be tempted to use Word or another word processing programme for this).

(This point selects the portion of the circle to be trimmed.)

Creates a pt variable that is a point on the circle.

Creates a variable el that is the name of the last object added to the database.

Draws a circle centered at (5,5) with a radius of 2.

If AutoCAD is at an idle Command prompt when these statements are called, AutoCAD performs the following actions: This command can prefarably be used with AutoCAD commands that makes multiple entities, such as array and divide since (entlast) only catches the last one. (command '._trim' el '' pt '') Performs the trim : (entlastlist) returns the list of entities created since the last issuing of the command (entlastlistinit). (command '._circle' '5,5' '2') Draws a circle

#AUTOCAD LISP USING ENTLAST IN A COMMAND UPDATE#

This routine developed in Autolisp, allows us to update any text, with the path and name of the current file. Replace a text with the current file path.

Enter an optionAll/Color/LAyer/LType/LWeight/Inherit from parent block/Explode : aNew Color Truecolor/COlorbook :Enter new linetype name for exploded objects :Enter new lineweight <>: 0.0Enter new layer name for exploded objects : 0Object exploded with color of BYLAYER, linetype of. To use the routine you must do the following: Load the lisp file in AutoCAD.

Select objects: 1 foundSelect objects:1 objects found.

#AUTOCAD LISP USING ENTLAST IN A COMMAND CODE#

The following example code demonstrates one method of passing an entity name and a pick point to the command function. Code: Command: xplodeSelect objects to XPlode. Points can be passed as strings within the command and command-s functions, or can be defined outside the function and passed as variables, as shown in the following example. First we must check that an ACADDOC.lsp file exists - to do this type at. Everytime a new drawing is opened, AutoCAD will search the Support Paths for any ACADDOC.lsp files, and will proceed to load the first one it discovers. Object and point data can be passed to the command and command-s functions without the use of a PAUSE, but requires you to first store the values as variables. Another way to load an AutoLISP program is to include a load call in the ACADDOC.lsp. Some AutoCAD commands (such as TRIM, EXTEND, and FILLET) require the user to specify a pick point as well as the object itself.
