You can display and edit tables of springs and restraints in the Data window.  You can use the commands from the Data sub-menu under the Display menu to control which table is on display at any time.

To change the value of a restraint or spring

§    Click on the number you wish to change

§    Type in the new value

§    Press the enter key

While editing numbers in the Data window you can use the scroll bars to scroll through the list of data, horizontally or vertically, to find the number you want to alter.  If you wish, you can use the Return or Enter, Tab or arrow keys to move to another number rather than pressing enter.

You can resize the columns in the table by dragging the lines that separate the column titles.  You can change the text font and size used in the table by using the Font… command from the View Menu while the Data window is in front on the screen.  The format of the numbers displayed in the table can be controlled by using the Numbers… command from the View menu while the Data window has focus.

You can also double click on the restraint icon at a joint (but not the joint itself) to modify that restraint.
