Displaying the Navigation Bar

After preparing the construction, you are now ready to display a navigation bar for the construction steps at the bottom of the graphics window.

In the "View" menu select "Navigation bar for construction steps". In the same menu uncheck "Play button" as well as "Button to open construction protocol".
Open the construction protocol of your file by selecting "Construction protocol" in the menu "View".
In the appearing construction protocol window click on "View" and select "Breakpoint" to get an additional column that allows you to specify groups of objects that should be displayed at the same time when navigating through the construction steps.
Check those construction steps that should be used as breakpoints when navigating through the construction. For example, to display the circle with center A through point B together with these two points, only check the box next to the last one of these objects - in this case the circle.
In the construction protocol window's "View" check "Show only breakpoints" before you close the construction protocol window.
