Constrained items in sketches moving

[Anonymous]

Hi.

Im having this issue where inside a sketch, i have constrained some items together. for instance 2 lines to be collinear. I then pick and drag an endpoint from a completely different line in the sketch and the constrained lines move and actually come out of collinearity but keep the constraint.??
Its happening with tangents, midpoints and even dimensions are randomly moving
I cannot work out what is going on.

Can you post a video?  More than likely the item you moved has a constraint on a common item with the colinear items.  Fusion 360 adds a lot of unnecessary constraints whenever you draw a new object, so you need to search for each one that may affect the move.
