| When the first point of the profile has not yet been selected and a circle is selected: | A semi-infinite dotted line is displayed, going through the center of the circle, and following the pointer position, which can then be moved around. It corresponds to the first point of the profile that will be created on a click.

The pointer is then constrained to move on the line defined by the first created point and the circle center. The second point of the profile is created on a click. |
| When the first point of the profile has not yet been created and two circles are selected in a row: | A semi-infinite dotted line is displayed, going through the center of both circles, and following the pointer position. It corresponds to the first point of the profile that will be created on a click.

The pointer is then constrained to move on the line defined by the center of both circles. The second point of the profile is created on a click. |
| When the first point of the profile has already been created and a circle is selected: | The pointer is constrained to move on the line defined by the first created point and the circle center. The second point of the profile is created on a click. |
| When at least one point of the profile has already been created, and two circles are selected in a row: | The next point of the profile is automatically created, as well as the next perpendicular segment of the profile.

|
| When at least two points of the profile have already been created and a circle is selected: | A semi-infinite dotted line is displayed, going through the center of the circle, perpendicular to the previous segment, starting from the intersection with this segment and following the pointer position, which can then be moved around. |
