Show constraints for one sketch object?

Auto constraints are killing me.  I spend more time hunting down errant and unwanted constraints than actually drawing.  The constraints become a visual jumble, and there is often no way for me to know what is constraining what.

 

Is there some way to select a single curve or chain and have ONLY the constraints for that curve show up?

 

Here is an example:

 

What constrains what?What constrains what?

 

I need to move one of these rectangles to align it to one of the sketch points.  But I can't.  It won't let me.  I don't know which constraint to try to delete.

 

Or how about this video cast.  I want to just move one of the text elements, but it apparently is linked through some constraints to the other.  I didn't ask them to be linked.  I didn't consciously choose to link them.  And yet, now I need to waste time trying to untangle them.

 

Is there not some way that I can select a drawing element and highlight ALL and ONLY the constraints affecting it so that I can quickly and easily see what is going on?  How do people effectively deal with these constraints in their workflow.  They are making the software almost unusable for me, at least when there are complex 2d drawings involved.

Hi,

 

In the Sketch Palette if you uncheck "Show Constraints" and then select an individual sketch segment, the constraints for that entity (only) should display.  Is that not happening for you?

 

Best regards,

Sanjay Jayabal.

Thank you, @sanjay_jayabal.  I did not know about that.  However, that still doesn't resolve the seemingly mysterious constraints I am constantly battling with that do not show up.  Perhaps it is not a constraint behaviour.  But if not, I don't know what it is.  Here is a screencast of what I mean:

 

I don't understand why the end of this curve appears constrained to the Y axis. My expectation is that it would stay the same length as I pulled the text around. What is happening here?

The sketch solver frequently solves things in a way that is perfectly logical to a computer, but doesn't make sense at first.

 

It is the end of that line that is constrained to the text block, so when you move the text block, you are only moving the endpoint of the line, not the whole line.

 

If you were to just grab the endpoint of a line, this is what you would expect to happen. 

 

If you want the length of the line to stay the same length, then you will need to constrain the length in some way, such as with a dimension.
