CAD tip # 13307:

For example, you can easily replace the currently missing SNAPANG variable control (in fact any variable control) used to rotate the cursor when drafting, by adding a simple LISP application.

Save the following LISP code into the Snapang.lsp file and upload this file in your web-based AutoCAD using "Manage LISP...". Set it to run at startup so that the new "SNAPANG" command is defined next time you start your web AutoCAD. You can then run it at any time by typing SNAPANG at the command prompt.

(defun C:SNAPANG ()
 (initget 1)
 (setvar "SNAPANG" (getangle "New snap angle: "))
)

As in the desktop version of AutoCAD, you can "pick" the angle by pointing two points in the drawing or enter it numerically (in the current angle units of your drawing).

Or an alternative, if you prefer more prompts for picking the angle:

(defun C:SNAPANG ( / p1 p2)
 (setq p1 (getpoint "Start point for snap angle : "))
 (if p1 (setq p2 (getpoint p1 "End point: ")))
 (setvar "SNAPANG" (if p1 (angle p1 p2) 0.0))
)
