Point Symbol Stroke Drawing

Point symbol creation involves drawing various graphical elements (geometries/strokes) in the symbol editing area. Strokes are categorized into four types: point, line, polygon, and text.

All objects must be drawn within the valid range of the symbol editing area. Drawing outside this range will trigger "symbol is out of the display range." warning and fail the operation.

The drawing toolbar shown below provides functions for creating different geometries, where each geometry represents a stroke.

After creating geometries using toolbar buttons, users can modify their styles through the style settings dialog.

Tip:
  • The style dialog displays different options based on selected stroke type.

Using Toolbar Buttons to Draw Strokes

Function Button Operation Description
Point Draw point:
  1. Click Point button;
  2. Click target position in editing area to create point. Repeat for additional points.
Line Draw polyline:
  1. Click Line button;
  2. Continuously click to place vertices in editing area. Right-click to complete.
    For precision drawing: Use parametric input (polar coordinates) with Tab key to toggle between length and angle parameters. Repeat for new polylines.
Arc Draw three-point arc:
  1. Click Arc button;
  2. Define three control points through consecutive clicks. Repeat for new arcs.
Circle Draw circular region:
  1. Click Circle button;
  2. Click to set center point;
  3. Click again to set radius, or input numeric value. Repeat for new circles.
Ellipse Draw elliptical region:
  1. Click Ellipse button;
  2. Define two diagonal points of bounding rectangle through clicks. Repeat for new ellipses.
Parallelogram Draw parallelogram:
  1. Click Parallelogram button;
  2. Define first edge with two clicks;
  3. Click to set adjacent edge. Repeat for new shapes.
Polygon Draw polygon:
  1. Click Polygon button;
  2. Place vertices consecutively and right-click to complete.
    Use parametric input (polar coordinates) with Tab key for precision edge drawing. Repeat for new polygons.
Rectangle Draw rectangle:
  1. Click Rectangle button;
  2. Define two diagonal points through clicks. Repeat for new rectangles.
Rounded Rectangle Draw rounded rectangle:
  1. Click Rounded Rectangle button;
  2. Define bounding rectangle with two clicks;
  3. Click to set corner radius. Repeat for new shapes.
Text Add text:
  1. Click Text button;
  2. Click target position to open Set Text dialog;
  3. Input content and configure font, size, color. Click OK to place. Repeat for new text elements.
