VV Lisp is also named as PRL lisp for AutoCAD. If you are working on a project where you need to draw cross-sections manually, then the VV lisp is a must-have for you. VV lisp is used to annotate the cross-sections or longitudinal sections. VV Lisp file Download link is given below feel free to download, use and share.
For longitudinal sections or profiles, it is used to write the chainage and elevations of the polyline vertices. You can use this lisp file to annotate the polylines that represent your finished levels and original ground levels.
For earthwork Cross-sections, PRL lisp for AutoCAD or VV lisp is very handy to write the elevations and offsets of your final ground and original ground. The use of this lisp is very easy and it saves a lot of time by automatically writing all the offsets and elevations of your cross-sections.

This lisp file writes the offset and elevations data correctly without any mistakes. While typing manually you can make any typing or calculating mistakes. The chances of mistakes are eliminated while we use VV lisp for our cross-sections.
The operation of the VV lisp is very simple and accurate. It uses the current coordinates system and X, Y locations of vertices along the polyline. The X value of each vertex is referred to as offset or chainage, while the Y value is the numeric representation of the Elevation of the vertex at that specific offset. PRL lisp is very hand and used by variety of drafters.
Credits go to the writers of this very useful lisp. The VV lisp is written by Mr. Muhammad Javed & Muhammad Ali.
How to use VV lisp:
First of all, you will need to draw the cross-section in AutoCAD and you must have a polyline drawn. Below the cross-section line, you need to specify the location of bands to show offset and elevations. When you have done so, follow the below-stated procedure to annotate your cross-sections with simple clicks.
- Enter AP command in AutoCAD command line to appload the VV lisp
- A new window will appear, browse to the file and click load, click on close
- Now enter VV in the command line to start the command
- The commands prompt asks to select the polyline, Select the polyline which you want to annotate
- Click at the base point for the X value. Click inside the band where you want to write the values of Offset or chainage
- Now again click inside the band where you want to write the elevation values when the command prompt asks you to click on the base point for Y-axis.
- Done! You will see the values written at the same alignment of your specified points.
Below is the complete tutorial video to use VV lisp.
Sometimes you may see some issues while using VV Lisp, like;
- the text is not written when the command is finished
- the values are written as zero
- Or the text size is very big or very small
The best way to deal with these issues is to copy your polylines to a new AutoCAD file and past at the original coordinates then appload and run the VV lisp command again. In some cases it may be named as PRL lisp
Moreover, try changing the current text style or text font. While using the lisp avoid zooming extent or zoom in too much.
I hope this is a complete guide to use VV lisp to annotate your Cross sections the fastest way, accurately, and without any extra effort.
PRL Lisp File for AutoCAD
Basically, the PRL lisp file and VV Lisp file both are used for the same purpose. Some people have saved the same file with the name of the VV.lisp file and Others have saved it with PRL.lsp. So in either case, you get the same result and file. Both files are used to achieve the same results in AutoCAD.
