The following links will download criteria files (*.CRI) for use in our PLS-CADD and
PLS-CADD/LITE programs. These criteria files are generic and intended solely
to provide you with the minimum requirements to meet the referenced codes. You may
need to adjust some of the parameters for your geographic locations, such
as the Extreme Wind and Extreme Ice cases, and add additional loading cases for your local and/or
utility specific loadings. Use of these files is at the user's risk, and as with
all projects, qualified Engineers should review them and modify them as necessary.
These files will work with Versions 8.10 and later of PLS-CADD and PLS-CADD/LITE. Should you need
to upgrade, please contact us at info@powline.com.
To download a file, simply click on it and then save it to your computer when prompted.

Once you have downloaded the files into your criteria directory you should run PLS-CADD. Now, in PLS-CADD or PLS-CADD/LITE, simply select Criteria / Load CRI File (near the bottom of the menu), locate and open the criteria file you downloaded. Be sure and read the notes section by selecting Criteria / Notes to see if the criteria are applicable to your projects. We suggest that the descriptions of the existing weather cases not be changed, as that will impact other parts of the criteria file. Modifications to the existing weather cases can easily be made and additional cases can be added and applied as necessary.
A few points of clarification should be made to fully understand the NESC 2002 files (these do not apply to the 2007 NESC criteria files):
