Accepted values are made available in the option menu for continued use.

Tip: Setting the Slope to 0 (zero) turns off the slope for a selected form.

Key-in: ATFMODIFY ROOF2 SLOPE

Note: This tool is enabled only when the MDL application ROOFBLDR is loaded. Selecting the tool icon automatically loads the application. Because ROOFBLDR is not loaded by default when starting OpenBuildings Designer, the key-in listed for this tool will not respond if keyed in before using the tool icon.
