Arrow, callout, polyline, polygon, arc, image, spline, and leader tools for detailed PDF markup.

Drawing Toolbar

Advanced annotation shapes used in A&E review workflows. Enable via View → Toolbars → Drawing.

Arrow [A]

Drag from tail to head. An arrowhead is placed at the end point. Configure arrowheads in the Format toolbar.

Callout [Q]

Click to set the text position, then drag to set the leader line endpoint. A text box appears — start typing immediately.

Polyline [W]

Click to add vertices. Double-click, right-click, or press Enter to finish. Creates an open multi-segment line.

Polygon [G]

Same as Polyline but the shape auto-closes on finish, creating a filled polygon.

Arc [U]

Click for start point, click for end point, then click for arc point to define curvature. Creates a 3-point arc.

Leader [D]

Creates an arrow with a leader line (horizontal segment before the arrow). Ideal for detail callouts.

Image [I]

Opens a file picker to insert PNG or JPG images onto the PDF. Drag to resize while maintaining aspect ratio.

Spline

Click to add control points for a smooth Bezier curve. Press Enter or right-click to finish.

Double Line

Drag to draw parallel lines with configurable spacing. Useful for marking walls, roads, or boundaries in site plans.

Tip: Polyline and Polygon are ideal for marking complex regions on site plans — e.g., excavation zones, fire protection areas, or seismic zones.
