I have created a triangle with some parametric constraints. I have also created some Variables to calculate the angle (X). When (C) is at a higher point to (A-B), (X) will be a positive value. I have no issues adjusting for triangle ABC by inputting Lengths. When you specify a height below (A-B) at (D), I am able to calculate (X) which is a negative angle. My Question though is how to get the triangle to show triangle ABD, as the moment (X) is negative it doesn't update the geometry to reflect. All it shows is the last configuration set for triangle ABC. In other word, (A-C) becomes (A-D) and (B-C) becomes (B-D).
