Vector editing

On the Vector edting page, you can set up how you create and modify vectors. Setup consists of selecting the units and tolerances for search, snap, and weed vertices in screen pixels, meters, or feet. You can also select whether you want snap to be automatic.

The available options are described as follows:

Snap tolerance: Snap is used only on a line or at the start of an area edit. When you snap a line or area start to a vertex or a line, the snap tolerance limits the available lines or vertices to snap to, given the current position of the cursor.
Snap automatically: Applicable only in a line or at the start of an area edit function, with this check box selected, a line or an area is started or ended with a snap when you want to start or end the line, or begin the area while still within the distance of the specified snap tolerance.
Search tolerance: Limits the cursor search for a vector feature to select.
Weed vertices tolerance: Applies to digitizing line and area data. The value specifies the minimum distance between the last vertex digitized and the current pointer position within which another vertex can be digitized.

To set up vector editing

To set up the snap tolerance, do the following; otherwise, proceed to the next step:
1. In the Snap tolerance box, type a value.
2. In the list to the right, select a unit of measure that corresponds to the value you entered.
To turn on automatic snap, select the Snap automatically check box.
Tip: When digitizing, you can turn on and off snap by holding down the Ctrl and Alt keys while starting or ending a line or starting an area.
To set up the tolerance for a vector search, do the following; otherwise, proceed to the next step:
1. In the Search tolerance box, type a value.
2. In the list to the right, select a unit of measure that corresponds to the value you entered. Clicking the cursor within this tolerance of a feature selects it. Clicking within this tolerance of a vertex or node that is on a line selected previously highlights the vertex or node.
To set the tolerance for weed vertices, do the following:
1. In the Weed vertices tolerance box, type a value.
2. In the list to the right, select a unit of measure that corresponds to the value you entered.
