After defining general structure parameters necessary to generate snow/wind loads (envelope, spacing, and depth) for the snow/wind code - Eurocode 1 (EN 1991-1-3:2003 - wind and EN 1991-1-4:2005 - snow and several codes for individual European countries), you must also specify the parameters for the snow and wind loads.

In addition to the general snow and wind Eurocode1code, codes specific to the requirements of individual European countries are also available. Some options are available only for a specific code, which are described in the Help.

Additionally, the Polish code PN-EN 1991-1-3/4:2005 is available. The snow load code PN-EN 1991-1-3:2005 is a mandatory code. The wind load code EN 1991-1-4:2005 is an optional code (wind loads should be generated according to the Polish code PN-80/B-02010).
