Can't fully constrain a sketch

Hello !

 

It's my first post on your forum and I am relatively new on Fusion 360.

I mainly use Fusion 360 to make holes in aluminium plates and electrical boxes.

 

On an other project, I wanted to create a SUB-D (https://fr.wikipedia.org/wiki/D-sub) hole.

In my little project, I am nearly sure that my sketch is fully constrained.

 

I wanted to set one circle at the same distance from the square than the other. So I use "=" canstraint.
But it doesn't show a my circles in black.

 I have to put a hard value myself to get it black (the 7mm).

It's very disturbing to have blue lines when I think it should be all black.

 

Do you have an idea on the "problem" ?

 

If you need more informations, doesn't hesitate to ask me.

Thanks a lot for your help,
Sincerley.

Your thinking is correct and what you described above must fully constrain this sketch, if done correctly. I did it:

I wonder where is the problem. Could you export your file to *.f3d and attach it here so I can take a look?

Oh...I should learn to create ScreenCast too. ^^'

@dsouzasujay No problem for your link.
It's interesting. I haven't used yet symetry on Fusion 360.

My problem is exactly the one shown by @hamid.sh.
