Input

• Ability to draw in one of three views: XY, XZ, or YZ
• Members and joints are internally sorted into groups of planes and elevations with unique labels and coordinates
• Ability to move or delete entire planes and elevations instantly
• User-controlled grid settings
• User-controlled display color and settings
• Coordinate and object (joint and mid-member) snapping
• User-controlled accuracy and precision
• Axes orientation, cursor location, applicable units, and other settings are always displayed
• Ability to zoom and translate
• Ability to superimpose planes or elevations for comparison
• Message bar that displays helpful hints, messages, and procedures
• Ability to draw members by simply clicking on their end locations (joints are automatically created at member ends)
• Ability to generate members around a circle
• Ability to copy (or extrude) selected members and joints
• Ability to specify fixed or variable offset distance and rotation angle while copying (or extruding)
• Ability to mirror image selected members and joints
• Ability to delete or move joints and members with simple mouse clicks
• Ability to "undo" the last executed action

Output

• Selective printing allowing printing of results for all or user-selected members, joints, member groups, and load combinations
• User-selected input echo
• Joint displacements
• Joint rotations
• Support reactions
• Member end forces and moments
• Member segmental forces, moments, and deflections - in tabular and graphical formats
• Member summary listing all relevant input and output data for a member on one page
• Member segmental force, moment, and deflection envelopes (maxima and minima, resulting from all load combinations) - in tabular and graphical formats
• Group segmental force, moment, and deflection envelopes (maxima and minima for all members in a group, resulting from all load combinations) - in tabular and graphical formats
• Diaphragm displacements
• Summary report
