How do I move a rectangle by a midpoint of a side to intersect/align with another object?

I'm trying to replicate a relatively simple model I did earlier today in another program in OnShape to make a comparison of the time and effort involved between them.

And I got stuck.

I sketched a centerpoint rectangle over the corner of another rectangle.  Then I needed to move the midpoint of the left side of it until it intersected another, larger, rectangle drawn around the original.

And nothing I tried would let me do that.

How do you do that?...without having to put a point out there, then draw a line the exact length you need from that point back toward the corner of the inner rectangle, and then drawing the centerpoint rectangle on that line endpoint?

Roughly shown here:

You need to constrain or dimension it to that line. You will probably have to break some constraints to move it as it looks like it is fully constrained.

whtmountain, the rectangle you want to move has been constrainted fully, all its lines and points are black, that's why you can not move it , so delete the dimension 0.4, then drag the vertex on the top left corner to the left line, then it is ok !

@whtmountain , Currently your sketch is fully defined. you have to delete 0.4 dimension as @shanshan_xu suggested. After that you can move that rectangle. kindly refer below video for more detail.

Is there a way to slow down the video?  You draw it so fast, I can't figure out what you're doing.  It would be nice if it could be paused, but that would be something Onshape would have to fix.

This is a very old post, do you have problems with sketching in Onshape?
Many try this as a start.
