Configuring the Formats and Units parameters

此主题仅适用于 ArcEditor 和 ArcInfo。

The Feature Builder window has several properties that can be customized on the General pane on the Feature Builder Settings dialog box including the precision of coordinates, the function library to use, snapping, and the spatial reference extent. The Formats and Units category contains options that pertain to the units of measurement used for angular and linear values, as well as the units of measurement. You can also toggle whether or not rounding is used with precision to estimate numbers accordingly.

步骤:

1. Start ArcMap.
   提示:

   If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

2. On the menu bar, click Customize > Toolbars > Production Feature Builder.
3. Click the Launch Feature Builder button on the Production Feature Builder toolbar.

   The Feature Builder window appears in ArcMap.

   The Feature Builder window

   提示:

   The Feature Builder window can be placed anywhere in ArcMap, or in the TOC, with the aid of the arrows showing the possible placement positions.

4. Click the Settings button at the top of the Feature Builder window.
   The Feature Builder Settings dialog box appears.
5. Click General on the left-hand pane.
6. Optionally, click the cell next to Angular Precision and type a new value for the angular precision.
   This is the number of digits required after the decimal point for an angle.
7. Optionally, click the cell next to Linear Precision and type a new value for the linear precision.
   This is the number of digits required after the decimal point for segments and features that represent distances.
8. Optionally, click the cell next to Angular Unit, then click the drop-down arrow in the cell and choose a new unit of measurement for angular data.
   This is the unit of measurement to be used for an angle.
9. Optionally, click the cell next to Linear Unit, then click the drop-down arrow in the cell and choose a new unit of measurement for linear data.
   This is the unit of measurement to be used for segments and features that represent distances.
10. Optionally, click the cell next to Auto Coordinate Type, then click the drop-down arrow in the cell and choose the format you want coordinates converted to when they are input.
    This value indicates whether an input coordinate should be automatically converted to a projected or geographic coordinate system or left unchanged. This allows you to apply a mask to coordinates so they are consistent with the coordinate system you are currently using.
11. Optionally, click the cell next to Rounding On, then click the drop-down arrow in the cell and choose whether to activate rounding for the precision parameters.
    This toggles whether rounding is allowed for linear and angular data.
12. Click OK.
