To See or Not to See Previous tipster Andrzeg Gumula comes through with a way to pass secrets in your drawings. Turn Objects Invisible or Visible (Tip #2058) is a clever manipulation of the AutoCAD objects in Visual LISP. Load the LSP module and type INVIS to turn objects invisible. The objects are still in the drawing; they just have the visibility property set to off. Type VIS to make them all visible again. Now you can hide invisible messages in your drawings for future designers to find! Thanks again Andrzeg -- great utility and a wonderful example of good programming. |
