When you select a line or arrow that you've inserted into your Storyline project, you'll find that the Change Shape option on the Format tab is disabled (grayed out).
Since lines are one-dimensional objects, they can't be converted into two-dimensional shapes (rectangles, circles, etc).
However, if you need to change the beginning or ending style of a line (for example, if you need to add an arrow point to the beginning), you can do that without recreating the line. Here's how:
- Right-click the existing line, and select Format Shape.
- Then select the Line Style tab on the left edge of the window.
- Use the Arrow settings section to change the beginning and ending type and size.
