change the radius

hi there i need to alter the curves that are on the inside of this part, they need to have a radius of 5 to locate on my servo motor. i drew the square then tried to fillet but it gives me the opposite curve so i tried drawing a circle but that was on the wrong side of the bolt holes.

i know it will be something daft im doing.

It is unclear what you desire.  You mention curves on the inside but all the curves in your model are controlled by the first sketch.  If you want to edit them, simply edit the sketch.  If you want to add 5mm radii to the sharp inside corners, use a Fillet.  If you could markup a screen capture to define your needs, I am sure someone can easily help.

@mcnicollchris 

Do you want to learn how to do this correctly?

(Correct modeling would require starting over and following explicit instructions.)

 

Tips:

Anytime you see repeated dimensions - you are probably working too hard.  Get lazy!

Anytime you see blue geometry - you should stop and ask questions before continuing on...

Before we start - what is the purpose of these two lines?

Whenever possible and practical - make use of obvious symmetry about the Origin.

Create the two point rectangle to the right of the Origin as shown below...

Add a Midpoint constraint between the Origin and the left side vertical line as shown below.

What do you notice about the color of the lines?

Add a Horizontal constraint the construction line that you just created.

(Tip: Your line might already be Horizontal in which case Fusion will tell you the constraint is not needed.)

Add the 10mm dimension between the two left vertical lines in the two rectangles.

What do you observe about the construction line rectangle?
