The angle, bend angle and length, or figure x and y position and z-order, can then be modified and the figure will update as the changes are made. If there is no handle under the cursor then it will edit for the last handle clicked or the selected figures.
In the main window this will edit the segment for the red handle under the cursor or the figure position for the orange handle under the cursor. In the figure builder this will edit the selected segment. The solution is to position figures to specific values by clicking ' Input Segment Values' or ' Input Object Position' in the Edit menu or by using the 'I' keyboard shortcut.
