The tab contains settings for snap, ortho and polar tracking and allows to switch the grid on.
| ◆ | Dynamic Input - switches the dynamic input while creating and editing elements on/off. |
| ◆ | Snap on (F9) - switches snap mode on or off. Is used in combination with the Object Snap modes. The command is also available from the Editor tab. |
| ◆ | Object Snap modes - this section contains a list of snap objects. The option can be also found under the Editor tab. The Object Snap modes set the points to which the cursor will snap while creating or editing an object. Mouse cursor turns to the respective shape when it is pointed at any of the active snap objects. |
Polar Angles - defines the step for polar angle. The value is selected from the listed angles and can be 1, 5, 10, 15, 18, 22.5, 50, 45, 90. By default the polar angle value is 15. This setting is used in combination with the polar tracking mode and defines to which angles it will be stuck.
| ◆ | Grid on (F7) - switches grid on or off: |
| • | Auto - grid spacing parameters are based on the loaded drawing's size and are equal to one hundredth of its largest side.. |
| • | Step by X size (Step by Y size) - a distances between points along OX and OY axes. |
Unlocked  button points that step values along OX and OY axes are independent of each other.
Locked  button points that step values along OX and OY axes depend on each other. Step value along OY axis is counted proportionally to the value of step along OX axis.
