Configuring the Geometry parameters

Dieses Thema gilt nur für ArcEditor und ArcInfo.

The Feature Builder has several properties that can be customized on the General tab on the Feature Builder Settings dialog box including the precision of coordinates, the function library to use, snapping, and the spatial reference extent. The Geometry category contains parameters related to the geometries that are created with the Feature Builder. This includes the density of points in the feature, the distance between vertices when points are being geodensified, and snapping.

Schritte:

1. Start ArcMap.
   Tipp:

   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

   Tipp:

   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. Click the cell next to Angular Densification Ratio.
   This ratio is used to densify a geometry created mathematically. This is used whenever you need to densify a parametric geometry (one that is constructed using a mathematical formula). The smaller the ratio, the greater the precision with which you can represent a complex geometry as a densified shape. (The smaller the ratio, the greater the number of points generated.)
7. Type the value that represents the angular densification ratio you want to use.
8. Click the cell next to Geodensification Segment Length.
   This is the distance between vertices when geodensifying geodesics (geodesic arcs and great circle arcs).
9. Type the distance you want to have between vertices when geodensifying geodesics.
10. Click the cell next to Snapping On.
    This indicates whether snapping is on.
11. Click the drop-down arrow in the cell and choose whether snapping is on.
12. Click the cell next to Snapping Tolerance.
    This is the number of units to use for the snapping tolerance for the current edit session.
13. Type the number of units to use as an allowable distance between the new and existing features.
14. Click the cell next to Snapping Tolerance Units.
    This is the unit of measurement for the snapping tolerance.
15. Click the drop-down arrow in the cell and choose the unit of measurement to use with snapping.
16. Click OK.
