Agenda

Webinar instructions will be emailed 24-48 business hours before the date of the webinar. 

Please log into the webinar 15 – 30 minutes before start time.

Monday, April 28, 2025
9:00 am – 4:00 pm CDT

Attendees will need to download HydroCAD Sampler from:
https://www.hydrocad.net/sampler/index.htm

The HydroCAD Sampler is a functional evaluation program that allows users to create and save projects of up to 5 nodes. It provides most of the capabilities of the full HydroCAD program but is limited to 60 minutes of operation per session. It can be restarted any number of times. HydroCAD is Windows only .exe, so if this is an issue, please feel free to watch along during the presentation.
