The Input bar displays current cursor coordinates and allows you to control the coordinate system and the units they are expressed. You may activate snap to grid in drawing operations, using Grid snap button placed on the left side of Input bar (you may hit F9 key instead). Similarly, you may activate orthogonal snap, using Ortho snap button placed next to Grid snap buttonon the Input bar (you may hit F8 key instead). Both F8 and F9 keys are used as toggles.

The coordinate system name is displayed within the combo box placed on the left side of the input bar. In normal state the absolute coordinate system , denoted as OXY , is the only one accessible for inspecting current cursor coordinates. During editing actions, you may change it to the relative coordinate system denoted as @XY , or the distance – angle system , denoted as D<A . The values of coordinates are computed relative to the point defined recently. In some actions, like rescaling or rotating, you have additional possibility to control defined values by scale system (denoted as SxSy ) or relative angle system (denoted by @<A ), forced accordingly in appropriate phase of transforming action. Each time you may switch to other coordinate system at your will.

With Geographical Mapping option set, coordinate system combo box on the Input bar is completed by the following systems:

You may display and enter geographical coordinates in degrees (in decimal or DMS format), grads or radians using the presentation units combo box on the Input bar.

The presentation units are displayed within the combo boxes placed after each coordinate. The distance units are initially defined by document units (see Document – Properties option). The document units are marked in the combo lists by an asterisk placed in front of units’ name. Change of presentation units does not change the document units; however, change of document units forces resetting presentation units to new value. The angle units – accessible when angular value is displayed in appropriate coordinate box – may be chosen between degrees in decimal or DMS format, grads or radians.

After activating the coordinate boxes, you may write down your own values. It has sense only during editing actions, of course. You may activate the desired coordinate box by pointing with cursor and clicking, or simply by hitting the Tab key while defining the new point to activate the first coordinate. Write down desired value and hit Tab again to move to the second coordinate. Click the Enter button or hit the Enter key on the keyboard to force written values as if you clicked left mouse button into Drawing window with desired coordinates. During writing new values, moving the mouse cursor over the Drawing window has no effect on displayed values, because you have stared entering your own ones. If you want to withdraw your changes, click the Skip button or hit the Esc key on the keyboard to resume the input back from the Drawing window. Cut, copy, paste and undo operations also apply for the entered values.

If you move cursor on the XCoord or YCoord box (watch change of cursor’s shape) and leave it there you can use keyboard and enter your own data. Accept it by Enter button. Treat Input bar as alternative to the mouse source of data. In some cases you can enter an angle in degree units (while rotation interface is active) or scales for x and for y-axes (while resize interface is active).
