Im trying to work on a piece to 3d print that will interlock with itself. I seem to have everything constrained except for some circles that will be used for some magnets and the vertical pieces of the interlocking parts. I am not sure how to properly constrain these to make this work.
I am also trying to use the sketch\scale feature on the bottom cutout parts, but they don't seem to be working as expecting and I think it's due to the missing constraints.
Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?
I see a lot of missing constraints. Mostly Midpoint.
Why are these Construction lines showing as under constrained?
Could you be missing Horizontal and/or Vertical constraints?
Click and drag. What do you observe?
Easier to draw one half only and not trim the rectangle. To keep parts central I've used midpoint and vertical constraints. (tip, if you start the Horizontal\Vertical constraint, hold the shift key and move the mouse pointer over the midpoint of a line you can pick the midpoint while adding the vertical constraint). I used a parameter (Clearance) to add clearance to the bottom dovetail.
From the sketch just extrude then mirror for the other half. You could use a pattern but Fusion doesn't have a way to automatically join patterned bodies. File's attached.

Thinking about this a bit more and I've come up with a way using a pattern so you could create this with more than 2 sets of holes and dovetails.
Using parameters create a sketch like this that will stay centred using different settings.
Then an extrude and pattern faces.
Just adjust the count parameter for what you need. File's attached.
