Getting Help with a Function

The code that adds a lightweight polyline to the drawing calls a function named vla-addLightweightPolyline. Not only is that a lengthy term to write, but there are several functions whose names begin with vla-add that you will use to create entities. Rather than consulting a manual to look up the function name every time you create a program, let VLISP help.

To get help with using a function

  1. Enter the following on a blank line:
  3. Scroll through the list until you find vla-addLightweightPolyline.
  4. Double-click on vla-addLightweightPolyline.

    VLISP displays the Symbol Service dialog box for the selected function.

  5. Choose the Help button in the Symbol Service dialog box. (For ActiveX® functions, you will be directed to the ActiveX and VBA Reference.)

  6. Delete the changes you made to gpdraw.lsp; these were for demonstration purposes only. Also, close the Symbol Service and Apropos windows.
