|Summary||0003746: inconsistent constrain tool behaviour|
|Description||Using the symmetry tool on three points has different effects depending upon whether the tool is already active or is selected after the points have been selected. |
What appears to be expected behaviour ( according to hover hint) : select two points then a third about which a rotational symmetry of the other two will be established.
This works as expected for pre-selection of the points.
However, once the tool is active it is the second which acts as pivot.
This is inconsistent and especially confusing when trying to understand how this tool works.
|Steps To Reproduce||Bug described and trivial fcstd test file on the forum. |
There is also a suggestion for a more accurate hover hint , since this tool applies different symmetries depending upon whether a line or point is chose as pivot. This should me made clear to the user.

suggested hover hint clarification. See forum for more detail on differences in the symmetry applied in the two cases, which is clarified by the new text.
"Create a symmetry constraint between two points with respect to a line or a third point (S)"
"Create a symmetry constraint between two points: a reflection symmetry with respect to a line, or a rotational symmetry about a third point. (S)"
