Working with Control Points

Click and drag a control point to move it. The line segments connected to the control point will automatically resize to reach the repositioned control point.

Use any of the following methods to add a control point to a markup:

• CTRL-click on the desired location of the new control point and go to Control Point > Add.
• Hold down SHIFT and click on a line of the markup.

Use any of the following methods to remove or subtract a control point:

• CTRL-click on the desired control point and go to Control Point > Subtract.
• Hold down SHIFT and click on the desired control point.

Lines at acute and obtuse (but not right or straight) angles can be converted into arcs. To do so:

• To convert by control point, CTRL-click on the control point and select Convert to Arc. The first line connected to the control point will be converted to an arc.
• To convert by line, CTRL-click on the line and select Convert to Arc.
