Holes in a cylinder

Leggie

Hi I’m trying to draw a 142mm cylinder with it covered in 3mm holes at 5mm centers
It’s to make a filter basket
Is there an extension that will help
Thanks Dean

Draw the cylinder in an unfolded fashion, draw the holes and array copy as desired, the use the extension "Flowify" to turn it into a cylinder.

Ok thanks

If you work out the logic of the shape you can just use arrays.
Here I roughly worked out the number of segments needed then created one hole and made two arrays.
This hole is 1.5mm radius and the face is a 5mm square, and the cylinder is 142mm radius with 168 segments. It's not accurate, you need the correct circumference then divide by the 5mm centers, to get the true number of segments. I just did this by eye.
That was my guess from your info.
If you need thickness then I would make the hole with two faces in a wedge format.

Hi I managed to draw it by taking one segment of the circle (80 segments), pulling it up to the length and cutting the holes in that
50 holes per segment
Then I copied and rotated it 80 times, so now we have 4000 holes
It was scaled up x10, I tried to scale it back down but got the spinning beach ball and it just froze up
Any idea how to clean it up

Use the bare minimum of segments for your holes.

the file is too big to send

I'm not sure why you want to send it.
Just start again and use fewer segments in the circles for the holes, and be patient, doing anything with 4000 holes can take time.
And I'm off to bed.

By the way, how many users accounts do you have?

Leggie

I’m on the minimum
Only one account

Box

What is the minimum?

How can you only have one and yet you are leggie in one post and leggy in another.

As they found out in Blackburn, Lancashire.

I signed into my iPad and forgot which way it was spelt
24 segments

Fortunately I'd finished my coffee before reading that.

24 is the default not the minimum. You could use as few as 8 and still have the appearance of a smooth circle. The minimum is 3.

Just to keep you all happy.

Good thing the holes were very small!
