Scaling a sketch

I'm trying to scale this sketch by 1.5 times whilst retaining the parametric aspects; by editing all the dimensions with *1.5, but that is giving me errors on the dimension marked in the picture.

 

I cannot figure out which constraint is preventing me from scaling this dimension.

Some of your sketch lines are green meaning they are fixed and won't scale.

Also, in most cases you should not first create a body and then move it into a component but first create and activate a component and then start modeling. See Fusion 360's R.U.L.E #1 & 2

Using the move tool to position/orient components also is not recommended.

Also, I'd keep the fillets out of the sketch.

I recommend starting over from scratch and use the BORN Technique as much as possible and practical.

I would probably not have repeated dimensions.

Every single dimension is linked to ply thickness, so I don't understand why it won't scale, if I change the ply thickness. 

 

Why should I keep the fillets out of the sketch?

Because sketch objects colored in green means that at some point in time either purposely on inadvertently you applied the fix constraint to those sketch objects. When you change dimensions they remain fixed as the name indicates.

 

It creates more robust and computationally faster models to apply fillets as solid features where possible.
