Before running your program, save all the files you changed, if you have not already done so. You can choose File Save All from the VLISP menu, or use the ALT + SHIFT + S keyboard shortcut to save all your open files.
- If the project file you created earlier in this lesson is not already open, choose Project Open Project from the VLISP menu, then enter the project file name gpath; do not include the .prj extension. If VLISP does not find the project file, choose the Browse button and choose the file from the Open Project dialog box. Click Open.
- Choose the Load Source
Files button in the project window.
- Enter the (C:GPath) command at the VLISP Console prompt to run the program. If you have some debugging to do, try using the tools you learned in Lessons 2 and 3. And remember, if all else fails, you can always copy the code from the Tutorial\VisualLISP\Lesson4 directory.
Also, try drawing the path using both lightweight and old-style polylines. After drawing the paths, use the AutoCAD list command to determine whether or not your program is drawing the correct entity types.
