Holiday Notice: RISA Headquarters will be closed on Monday, January 20, in observance of Martin Luther King Jr. Day. We will reopen on Tuesday, January 21, at 6:00 am PT.
The new "2D Mode" in RISA-3D gives users a fast and easy way to analyze simple 2D structures like trusses, frames, walls and single beams by locking all nodes in the out-of-plane direction.
