The first sketch is ridiculously complex!  Fusion 360 does not handle sketches that complex very well.  You have to start using better modeling techniques such as moving your patterns into solid modeling.  I notice the sketch was probably imported as it is a base feature.   You probably will not like my solution, I got the sketch to open and I chopped off most everything not being used for the solid grating shown in the model.  If you need to get more grating, patterning in the model space is your answer, Fusion 360 handles that well.   I pattern the existing body three times in a blink of an eye.  My edit model is attached if you want it.

thanks for the help.

Where do i need to go to learn how to not make the drawing so complex.

You just need to think, "How could I achieve this with simple sketches?"

Let's consider a grating for example. Could you do it only sketching ONE hole, cutting that hole through a solid plate, and then patterning that hole as necessary?

For example, I've made this grate using this simple sketch and a Rectangular Pattern of the hole Feature.

Hi and thanks for posting. As you see @jhackney1972  has provided a model that shows an efficient process for a design like this. If you down load it, then open Fusion and use File > Open, you can open his design and examine how it was built.

Just for your information, the Fusion compute thread (the one that is engaged when you edit this sketch) is also the main UI thread. What this means is for a complex operation, Fusion is not crashing, it's computing. Have some patience when creating massive sketches or patterns if it takes a few seconds to compute. In larger models this might be a minute or two.

Let me know if you are interested in tutorials, Fusion has a bunch of built in learning content for new users.
