I need to generate a cube with uniform spherical holes

[Anonymous]

I need to generate a cube with uniform spherical holes...like the one attached BUT with thicker walls to be strong enough for 3d printing

[davebYYPCU]

Edit cube and or sphere size, or pattern count.

Might help....

Have you made an attempt at this?

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

I need to thicken the walls vertically and horizontally which means reduce the size of pores...how can I do this?

The file that you linked (not sure why you didn't Attach here as requested) is not a Fusion *.f3d file?

I could create the geometry for you - but this doesn't give me any indication about what you need to learn in Fusion to complete the task yourself.

You will want to learn

Extrude

Revolve

Pattern

Are your intended units mm, cm or inches?

Sorry for my mistake

here is the file in the requested format

I need to output the file 20 mm3 volume with spherical pores of pore sized 2 mm diameter

This is not a native Fusion file.

This is an stl file imported into Fusion.

Did you make an attempt to model the geometry yourself?

Above is image of my attempt.

Notice that you will have a Timeline record of your attempt including Extrude Revolve and Pattern.

I found the .STL file. Now I need to edit it..would you kindly set me a written script of steps so I can follow them? how to edit the meshwork? so that I would change the pore sizes?

[JDMather]

How much training/experience do you have with Fusion 360.

This would make a good example to gain modeling experience.

STEP 1. Start a new file.

Sketch the square as shown.

Extrude the square by the same dimension into a cube...

well, Sir.I appreciate your help to the max

I do not see any dimension(s) on your sketch?
Blue lines should keep you awake at night.

How big is your square?

I find it very difficult to pursue working at 3d modelling with fusion 360>>> I can do the final touches at a slicer program like meshmixer or prusaslicer before 3d printing

[TheCADWhisperer · Accepted solution]

A square and 4 circles.

Can be made fully parametric and trivially easy to edit.

[davebYYPCU]

Slicers will not change what you have asked for, 

scaling the box size can be done but the holes will be proportionate.

You need to model your own block with the new required sphere size.

I think you might be looking too far forward.

Drawing a square is 2D - about as simple 2D as you can get.

The only thing more simple is a 2D circle.

So this entire problem reduces down to drawing a square and a circle.

Fortunately enough>>Prusa Slicer, Cura..etc have a certain option named "Horizontal Compensation" which reduces the size of the holes
