How can the direction of an arc be changed?

1. Change the arc properties in the layer settings.

2. It can be overridden by using the Control key.

3. Edit the arc's direction through the properties panel.

4. Use the Properties palette to adjust the arc.

The correct answer is: It can be overridden by using the Control key.

The direction of an arc can be effectively changed by overriding the default behavior using the Control key during the creation process. This method allows the user to redraw the arc in the opposite direction, providing flexibility in how the arc is oriented without needing to change any underlying properties or settings. Using the Control key is a straightforward approach during the drawing stage, which gives the designer immediate feedback and allows for rapid adjustments without going through additional menus. This feature is particularly useful for draftspeople who may want to quickly experiment with different orientations of their arcs. The other choices do not provide methods to change the arc's direction effectively during the drawing process. For instance, while editing properties in the properties panel or the Properties palette can adjust attributes such as length, layer, or color, they do not allow for dynamic adjustment of an arc's direction once it has been created. Additionally, changing layer settings might affect visibility or organization of objects but does not influence the drawing direction of the arc itself.
