Okay, so this is one of the "I can do this in Solidworks, WTF Autodesk?" questions.
I am having some issues with sketch constraints hiding in plain sight. In a controlling sketch, I made some errors with control points in a spline, and I would like to correct them without deleting the spline - it's referenced downstream, so I need to preserve it. I also need to preserve the absolute location of one spline's terminus, but if I move it temporarily I won't be able to reference that location again.
One part of this problem is I can't move some of the control points. They seem to be referenced to a point I sketched earlier and I can't see. That's the genesis of this question... Why can't I see every sketch relation for a given sketch entity? The only one I have access to is the one on "top", and even then I only get a single coincident constraint, even if there are three other points below it, each related to each other.
I want to preserve the absolute coordinates of the two intersection points between the paralllel splines and the horizontal spline in the attached image, and I want to trim the excess spline from above it. Additionally I want to fix those points - one of which already is.
Since I sketched these entities, I have learned to sketch points and dimension and mate them first and then sketching a spline separately, and then dragging the fit points to them. That didn't happen here, and that's why I'm lost on how to fix this.
In my experiments, I was able to do almost all of what I need, with the exception of the right intersection refusing to budge, even though it was a white dot. I think there must be a hidden constraint underneath I can't see.
Before:
After Trimming:
I need to capture the absolute coordinate of the blue spline terminus:
Because I can't see every sketch relation in a list, I can't just anchor a point and then delete and reestablish the coincident constraint, or at least that's how I'd do it in Solidworks.
In fact, I can't even move the white dot. It is locked down, and I see no constraints. What could be locking it?
