Trying to Do - - - > Constraint - Square inside Rectangles

[delaing]

I am trying to sketch a dimensioned rectangle to be centered inside a second dimensioned rectangle using constraints. Yesterday, I was attempting to use the focus-to-midpoint-Shift key trick/method which is outlined in various tutorials and in a post reply by @jhackney1972 , but I cannot get it to work.

Here is a link to his cast showing the approach.

I am receiving error messages, when selecting a rectangle side - "Constraint has already been applied".

What am I not understanding?

Thanks in advance,

Delain

 "Constraint has already been applied".

You can't do it twice....

I guess I wasn't clear with my problem.

In John's cast tutorial, he receives the same error since there are already constraints existing for his rectangles. That is not the issue.

Trying to duplicate his actions with using H/V constraint to move the square to be centered by holding the Shift key to find midpoints and then move the square - - does not seem to be allowed when I'm trying to do it.

Here is another explanation of this approach to centering a rectangle inside another. See Message #3 where @FrankCao lays out his solution.

I cannot make the Shift action work.

Until you supply your data, we can't explain it for you.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Shift will reveal/show the target's midpoint, but the attempt to apply the H/V constraint (as outlined in the mentioned solutions) fails to work.

Attached is a simple file with two rectangles sketched. Attempting to constrain the smaller to the larger so the smaller is centered within the larger.

Can you create a Screencast Recording of your steps?

Good grief!!!

One simple oversight on my part when reading/watching the other solutions.

So I was not holding down Shift prior to picking the first line of the smaller rectangle. I picked the line first, then held Shift when hovering over the second rectangle's line, thinking I was trying to reveal that one's midpoint.

I should be kicked out of the Fusion 360 Operator's Union for that.

Good grief!!!

Thank you Top Daug for making the cast to show me my oversight. Thank you!!!!

You need to watch my Screencast a couple more times.  It distinctly points out that you need to hold the shift key as you are trying to hover over the line to find the midpoint.

Yes, and I mentioned, I missed the simple point of holding Shift prior to picking the first line of the square/rectangle.

Thank you,
