I can't help but mention that there would be a more efficient way to build your model.
Your sketch is rather complex and could be broken down into successive operations. For one thing your profile appears symmetric, in such cases it is almost always best to centre it to the sketch origin. This is useful for later operations.
You could also only model half of the sketch, pad it then mirror the solid using Part Mirror
, and finally fuse the original and the mirror with Part Union
The many circles in the sketch could be done in a later step. Just sketch a single circle on top of the solid, pocket it then repeat it with a PartDesign MultiTransform
feature containing a LinearPattern along the horizontal axis and a LinearPattern along the vertical axis.
The end result would be done in more steps, but all of them would be accomplished much more quickly than with a single sketch.
