Polygon Edit Tools:

NOTE:

All the actions can be undone using CTRL+Z.

Main Tools

Priority Control Panel - Before adding new polygon or editing an existing one the user must specify the PRIORITY of this feature.

Select Tool - see description here

Add Shape Tool - adds new shape to the current theme. Use CTRL + Click to select shape type from the available shape types are:

• polygon - draw
• rectangle - drag (hold CTRL key to draw a Square with side equal to the shortest side of the rectangle dragged)
• circle - drag
• rectangle - lower left corner, width, height, rotation angle
• circle - center point, radius
• ellipse - center, axis1, axis2, rotation angle. Note: Not available with the version for ArcView 3.0

Add Donut Tool - adds new donut to the current theme. Use CTRL + Click to select shape type from the available donut  types are:

• rectangle - drag + donut width (hold CTRL key to draw a Square with side equal to the shortest side of the rectangle dragged)
• circle - drag + donut width
• rectangle - lower left corner, width, height, rotation angle, donut width
• circle - center point, radius, donut width
• ellipse - center, axis1, axis2, donut width, rotation angle. Note: Not available with the version for ArcView 3.0

Fill Holes Tool - the user selects polygons using the current selection method, the holes if present in the selected polygons are cleaned. Use CTRL+Select to convert the holes into new polygons

Reshape Tool - the user draws a polygon, the start point should be in the polygon to be reshaped. Only two values for  priority available for this function - "0" and "2".  If the priority is set to "-1" it goes automatically to "0" and if "1"  - to "2"

Example:

Before Reshape. The reshape polygon and it's start point shown on the image.	After Reshape with priority of "0". Ideal for filling gaps.	After Reshape with priority of "2"

Buffer Polygon Tool buffers single polygon selected by point

Example:

Before buffer	Priority  = -1	Priority  = 0	Priority  = 1	Priority  = 2

Explode Tool Explodes selected multipart polygons

Merge Tool User selects with a line two adjacent polygons. The polygon that contains the start point of the selection line is merged with the one containing the end point. The attributes of the second polygon are kept.

Local Dissolve Tool User selects a single polygon by point. All the adjacent polygons with the same value in the selected dissolve fields are merged to the selected polygon.

Copy From Theme Tool Use SHIFT +Click to select source theme. Use current selection method for selection. The selected polygons are added to the Current theme using   current PRIORITY.

Draw Line Buffer Tool Use CTRL+Click to define buffer distance. User draws a Polyline which is added to the current theme using current PRIORITY

Copy Line (Point) Buffer Use CTRL+Click to define buffer distance.Use SHIFT +Click to select source polyline or point theme. Current selection method is used. Buffers selected features from the source theme and adds the buffer polygons to the Current theme using  current PRIORITY.

Select polylines from a theme and split Tool Use SHIFT +Click to select source polyline  theme. Select polylines to split with. Only polylines connected via pseudo node will be used for splitting. Adjust attributes split rules before this procedure.

Attribute Tools - See description here

Additional Tools

They are situated on the second row (together with the attributes tools),but can be as useful as the ones from the top row:

Draw Advanced Buffer Tool and Copy Advanced Buffer Tool work as Draw Line Buffer Tool and Copy Line Buffer Tool. The difference is they allow more complex buffers to be created:

• various buffer distance - user defines start and end buffer distance (linear interpolation in between)
• buffering with or without caps
• one side buffers - user defines left or right side of the line (direction taken into account)
• various combinations from the above

CTRL+Click (on both tools) invokes Advanced Buffer Dialog which allows the user to specify the type of buffer and the buffer distance Examples:

Gaps Control Panel contains two buttons. The first identifies the gaps in the Current theme and fills the gaps list. The second one zooms to each gap in the gaps list and the user can clean it manually using Polygon Reshape Tool. If some of the gaps can not be cleaned with the automatic procedure, or the user wants to inspect the gaps this buttons can be used.
