Change
Use this command for block operations such as changing friction coefficient for all guides and limit stops within a range of rows, or changing the material, section or load for a range of rows or level tags for all supports (available only when spectrum and spectrum level defined) or span length (i.e., DX, DY and/or DZ between adjacent nodes) for a range of rows. You are asked for the range when you select this command from the Edit menu.
