To demonstrate the use of projects in VLISP, you can use the sample programs supplied with the AutoLISP Tutorial. This code is available on the AutoCAD ® installation media, but the tutorial files are only included if you performed a custom installation and selected the Tutorials item. If you have already installed AutoCAD and did not install the samples, you can rerun the installation, choose Add or Remove Features, and select only the Tutorials item.
The sample files used in this chapter are in the Tutorial\VisualLISP\Lesson5 folder of the AutoCAD default installation directory. The files are
- Gpmain.lsp
- Gpdraw.lsp
- Gp-io.lsp
- Utils.lsp
To create a VLISP project, click Project 
New Project from the VLISP menu. VLISP displays a standard Windows dialog box for you to specify a file path and name. For the example in this chapter, the project name is Tutorial. VLISP assigns a .prj extension to the project file name.
