I have a question regarding the sketch shown in the images.
The two lines (marked in red) are constrained with tangency to one of the circles (marked in purple). However, if tangency is the only constraint applied to the lines, they could just as well be tangent to the opposite side of the circle. This implies that the sketch has multiple valid solutions (four when considering just those two lines).
From my observation, Fusion resolves this by selecting the first valid solution it encounters—typically depending on the initial position of the line. For example, if a line is closer to the bottom of the circle, it becomes tangent on that side, and vice versa.
As a sidenote, if the vertical line is also taken into account, the number of possible solutions increases further (up to eight in total).
I understand that this situation can be fully defined using additional constraints, and that there are workarounds to avoid the ambiguity. However, my intention here is mainly to highlight this behavior and better understand the underlying logic. I have included images showing two of the eight possible solutions for illustration.
Would it be possible or beneficial to have an additional constraint or option that explicitly defines on which side of the circle the tangency should be applied?
Thank you in advance for any insights!
