How to make mesh filter models?

[MichaelSGao]

I´m trying to make a model of a mesh filter with the filter plate itself has a diameter of ~12 cm and the diameter of the holes is 1mm.

Only one quarter of the sketches were drawn in my design, the computer couldn´t handle these details properly already...

I Had a peek over this: https://help.autodesk.com/view/fusion360/ENU/?guid=Fusion_Simulate_concepts_sim_f360_mesh_mesh_guide.... 

I´m not sure wheter this guideline is talking about the exact problem that I´m facing. What is the efficient and correct way to get this job done?

I guess the first question is:  What is your goal in modeling this mesh?  Do you NEED the actual mesh geometry to be modeled in 3D?  If so, for what purpose?  Are you planning to manufacture this mesh using a 3D printer?  Are you planning to do some fluid simulation on the mesh?  If there is no real need for the 3D geometry, I would not attempt to model it - just use an appearance or a decal to show the mesh.

Now, if you do really need the geometry, then definitely do not attempt to do it in sketch.  Make one hole in the Solid environment, and pattern that hole using Solid Pattern (Optimized or Face Pattern).  Even then, depending on how big the mesh is, it may take some time to compute the results, and the model will be very heavy.

Thank you @jeff_strater for the follow-up questions and your answer.

Yes, I do need the geometry, both for 3D-printing and for fluid dynamics simulations.

Let me see whether my PC will work better on replicating the hole pattern.

I've downloaded and opened your file. I'm no expert but as a basic rule keep your sketches simple. If in the end, you need a disk with a thousand holes your sketch should be the Circle that is the disk and just ONE circle for the many holes. You pattern the "hole", not the circle.

Many thanks to both of you! @jeff_strater @Warmingup1953 

I´ve successfully made this filter model by replicating a single extrusion (cut) pattern for many times.

I also had a look at this dicussion and it turned out that even the fastet optimized-type computation already took a very long time in my case... Anyway the final outcome was what I was hoping for.
