Attributes such as scale bar, Visible Bounds:, center point, view range, and Map Bounds are included in the Range option on the Map Properties panel.

Current scale

Used to display and set the scale bar in the current Map. As the map zooms, the value of the current scale constantly changes. You can enter the scale denominator value to be displayed in the text box to the right of the Current Scale label. When you click Enter, Current Windows will display the entered scale.

Fixed Scale

Check this box to enable map scaling with Fixed Scale, which defaults to the national standard scale. Support customizing a series of scales as Fixed Scales. When zooming the map, the result of each zooming operation will switch between these Fixed Scales. Current Map will not display the scale range outside the Fixed Scale. Custom Fixed Scale refers to Custom Fixed Scale.

Crop Display Range

By setting a certain range, only the map content of Specify Range is displayed in the current Map, and the map content other than Visible Bounds: is not displayed, so as to present a map clipping effect. Clipping a map is a process for display purposes that does not clip individual Datasets of the map.

When the Crop Display Range check box is selected, the Drop-down Button on the right becomes available. Click the Drop-down Button and select a cropping area method in the pop-up drop-down menu to determine the cropping area in the current Map. Select Object, Draw Rectangle, Circle, Sector and Polygon are provided in the drop-down menu. Among them, Select Object supports selecting one or more face objects in the current Map as the clipping display area. After determining the crop area, Current Map applies the crop effect in real time.

Lock Maximum Display Bounds

The function of Lock Maximum Display Bounds is to Lock a specific part of the map through the maximum display range, so that the Visible Bounds of the map are maximized during Map Browsing. Even if the map contents outside the Specify Range are not visible in the Lock Maximum Display Bounds state. This function is similar to the function of cropping area. The difference is that the map after the operation of cropping area can be Free Zoom or panning, and is not controlled by the set range. When the map is locked, various Map Brow sing operations will not make the Visible Bounds: exceed the Specify Range.

• Select the Lock Maximum Display Bounds check box, and the Drop-down Button on the right becomes available. At this time, the maximum map Visible Bounds: the default is Map Bounds. Click the Drop-down Button and select a method to lock the range in the pop-up drop-down menu to determine the area to be locked in the current Map. The drop-down menu provides a series of ways to determine the lock range: Draw Rectangle, Circle, Sector, or Polygon, and by selecting the range of a face object in the current Map as the lock range.
• When the lock range is determined, the Current Map immediately displays the maximum of the determined lock range.
• If the user is not satisfied with the current locking range, he can click the Set as Map Bounds option in the pull-down menu of the button to Set as Map Bounds the maximum range of map locking; or determine a new locking range, and the executed locking range operation will be cancelled automatically, and the new locking range will be applied.

Custom Full Bounds

The function of Custom Full Bounds is to customize the Full View range of Current Map by setting. After the user defines the full-frame range in the Current Map, after the Map Browsing operation is performed on the current Map, if the user clicks the Full-frame button in the Browse group in the Map tab or presses the F6 key on the keyboard, Current Map will be in Full View with customized full width.

• When the Custom Full Bounds check box is selected, the Drop-down Button on the right becomes available.
• Click the Drop-down Button and select a setting method of Custom Full Bounds in the pop-up drop-down menu to set the full-width range in the current Map. The drop-down menu provides a series of ways to determine the full extent of the map: Draw Rectangle, Circle, Sector or Polygon, and by selecting the extent of a face object in the current Map as the locked extent.
• When the full range is determined, Current Map immediately zooms in on the determined full range.
• If the user is not satisfied with the current full-width range, he can cancel the executed full-width range operation by clicking the Clear Custom Bounds option in the pull-down menu of the button, or determine a new full-width range, and the executed full-width range operation will be cancelled automatically and the new full-width range will be applied.

Centre Point

Centre Point: Displays or sets the Center Coordinates value of the current Map in X, Y coordinates. The spin boxes to the right of the X: and Y: labels are available and display the coordinate values of the center point of the current Map. You can reInput Data: in these two spin boxes to determine a new Map center point.

Current View

Allows you to view information about the extent to which the map is visible in the current Map. The information of the Current View includes the Position Info of the left, top, right, and bottom displayed by the Current Windows. These text boxes can be edited by inputting the coordinates of left, top, right and bottom. The current Map Scale will not change, which is equivalent to the translation of the map.

Application provides four setting methods: Current Windows, Whole Map, Select Object, and Copy and Paste. The specific description is as follows:

• Whole Map: Click to select the Whole Map radio box to set the union of All Layers ranges in the Current Map as Export Bounds;
• Select Objects: provides two methods: Select Object and Draw Bounds. Select Object refers to selecting one or more objects in the current Map through the mouse box or click. Select ObjectsRange Settings as Export Bounds; Draw Bounds means that a rectangular area is determined as Export Bounds by clicking Draw in the current Map.
• Copy and Paste: Click the Copy button to Copy the range of the Current settings. Click the Paste button at the Range Settings that supports paste to set the left, lower, right, and upper values of the Copy Bounds to the current range.

Map Bounds
