Draw widget

The Draw widget allows users to create simple graphics for points, lines, and polygons on a 2D web map or 3D web scene. Users can add measurements to drawn graphics for coordinate position, length, perimeter, and area.

Examples

Use this widget to support app design requirements such as the following:

  • Town planners can draw lines for rural roads.
  • Construction site managers can create polygons of underground utility features.
  • Conservation agents can draw points representing wildlife sightings.

Usage notes

This widget requires connection to a Map widget.

When you include this widget in an app, a panel or toolbar provides users with the following tools for drawing features.

  • Select feature, Select by rectangle, and Select by lasso—Choose a method for selecting drawn features. When you draw on 3D web scenes, only Select feature is available.

  • Draw a point, Draw a polyline, Draw a polygon, Draw a rectangle, and Draw a circle—Sketch a feature on the map or scene.

    • Preview—View a preview of the symbology of the feature to be drawn.

    • Source—For points, select from a list of categories containing premade symbols. Different symbols are available in each category.

    • Symbol customization options—Select a predefined symbol from the box. Customize the symbol using the following settings:

      • Points, customize size, fill color, outline color, outline width, and fill transparency. Only the size setting is available for picture point symbols.
      • Polylines, customize width, dash type, color, and transparency.
      • Polygons, rectangles, and circles, customize fill color, outline color, outline width, and transparency.
    • Measurement tools—Include relevant measurements in appropriate units on drawn features.

      • For points, turn on Show location measurement to include degree minute second (DMS) or decimal degree (DD) measurements.
      • For polylines, turn on Show length measurement to include kilometer, meter, mile, or feet measurements.
      • For polygons, rectangles, and circles, turn on Show area measurement to include square kilometer, square meter, hectare, acre, square mile, or square feet measurements. Turn on Show perimeter measurement to include kilometer, meter, mile, or feet measurements.
  • Undo and Redo—Undo or redo actions. These buttons are based on the actions performed using the widget.

  • Clear all—Remove all drawn features from the currently active web map.

  • Expand and Collapse—When using the widget in toolbar mode, expand or collapse panels associated with the widget, including the customization panels for points, polylines, and other features.

    • Enable measurement—Allow users to include measurements on drawings. Choose which units to include.DD and DMS are angular units used with points. Kilometers, Meters, Miles, and Feet are used to measure length for lines and perimeter for polygons, rectangles, and circles. Square kilometers, Square meters, Hectares, Acres, Square miles, and Square feet are used to measure area for polygons, rectangles, and circles.

    • 3D drawing effect—Choose a height method for drawing 3D features.

      • Relative to ground—Draw features that are at a known height relative to the ground, like a rectangle representing airspace over a town.
