Tips:

 

1.  Use Modify > Undo to undo the last step.

 

2.  Use table input when you want to combine it with graphical input, or when you are not comfortable with graphical input.

 

3.  Try to remember some useful keyboard shortcuts

UP or DOWN or LEFT or RIGHT for panning

[CTRL] + UP or DOWN or LEFT or RIGHT for zooming

[SHIFT] + UP or DOWN or LEFT or RIGHT for rotating

F8 for quick rendering

ESC to clear selection or get out of trouble.  Press twice if you have to.

 

4. Views and selections may be saved and recalled.

 

5. Use 128-bit floating point skyline solver for numerically sensitive structures such as one with rigid diaphragms.
