How to set a midpoint constraint on the horizontal?

[autodeskN884Q]

I have a sketch like this

Now I want to align these two rows horizontally with a constraint.

I've added a line as helper 

And added a midpoint constraint to the two selected edges

This aligned the two rows horizontally which is what I wanted. But it also pulled the line and it's attached rectangles up. What am I doing wrong?

Thank you

I am not totally sure if I understand your issue but I will go on my gut feeling.  Watch the Screencast and see if I am correct.  I went ahead and added another constraint to the origin and one dimension to fully constrain your sketch.  Model is attached.

Thank you once again for your support.

Unfortunately that's not what I was looking for. I should have been clearer in the first palce, my bad.

This is my sketch

And no I want Row 2 to be horizontally centered to Row 1

Roughly like so 

Hope that makes more sense now

What am I doing wrong? with this and the other question, - Not follow convention or training methods.

Missing, 

Reference to Origin, 

Symmetry

Equal constraint

Sketch pattern with out pattern icon

This file is so different to the other sketch, not sure what to recommend.

Blue lines are not recommended, 

Sketch patterns are not recommended

Reference to Origin is recommended,

Equal Constrain is recommended.

Make one cube and pattern it (Body or Component).

Sketch is edited to get you close.

Construction Line - Midpoint constraint, and most is useable....

Might help....

Blue lines are not recommended? Sketch patterns are not recommended? I followed Lars Christensen's youtube tutorials. He is using them. I thought I was going at least in the right direction.

Also it's a little confusing there is no ref. to an origin? I created the sketch on an origin.

I got it now.  I cannot tell if the top row is, not only centered, but on top of the bottom row.  I did it both ways in the Screencast.  Please note, you can find the midpoint of a line by holding down the Shift key and hovering over the approximate center of the line in sketch mode.  This is shown in the Screencast.  Model is attached with the top row centered and on top of the bottom row.

[jhackney1972]

In the Screencast I place the necessary sketch constraints to place your model at the origin.  You normally will not be constrained to the origin by just starting the sketch on it, depends on your settings.  You can add a sketch constraint to do it after you have sketched the lines.  Just watch the Screencast closely.

You don't get symmetry with that box corner "near" the origin. 

Not using the origin until it turns black (white in John's scheme)

Horizontal Construction line with midpoint does.

Mid point in the next row is Vertical to Origin and most turns black.

From the Other question you want a Christmas Tree made of building blocks.  

Make one Block, then make those in patterns.  Much easier.

Make a 80 x 80 x 80 cube, pattern with 90 spacing.

This simple one has no sketch, but offset rows are just as simple....

Might help.....

What is the link to the Tutorial that you are using as reference?

I didn’t open your file, but from the images I see a lot of redundant work.

Any time you are doing the same thing more than once - you are probably working too hard.  Get lazy! Let Fusion do the work for you.

Use symmetry about the Origin.

Blue lines and white dots should keep you awake at night - time to ask questions at the first one.  Don’t create a bunch more.  What exactly is your Design Intent? What are you modeling.  Someone will show you a more efficient technique.
