Holes with different diameter on a line

kzycek — Mon, 23 Oct 2023 10:07:59 GMT

I have a rectangle where I on the center axis on the top surface would like to place a number of holes evenly placed on the center axis. This is easy with even sized holes but in this case all holes are different diameter.

I reckon this can be done in a smart way but can someone point me in the right direction?

Alternatively I could of course simply do the math and then place the the holes... but since Fusion 360 is so smart, I figure I should look for the smart way of doing this.

Do you have an image or a model of exactly what shape you want to create? Could you share additionally?

Hi,

You can only set the center points for the circles in a rectangular pattern. The different circles must be created manually, if necessary with previously defined parameters.

Hi,

Are you modelling the holes and then drilling manually or CNC? The easiest way to get any regular line,

rectangle or circular pattern is with the Pattern tool. It will give you evenly spaced "objects" but I don't

know about changing size for each hole. It might be worth it to model pilot holes and either tell the CNC

to change size or drill manually with appropriate drill.

Maybe one of the Gurus of the Forum know a way. It is probably some arcane majical trick us mortals haven't

learned yet.

Cheers

Andrew

I have attached my sketch and after a little thought, I guess what I need to do is make a center construction line with the number of centres I need.

On the picture I have aligned the holes manually.

As I mentioned elsewhere I already did a manually placement and I am starting to believe that my first mistake was to make different sized holes placed randomly on the surface. I probably should have made a center construction line with some kind of center marking for the number of holes I intended to make.

You can mark the places where the circles will appear with the rectangular pattern command, then you need to draw each circle manually. Unfortunately, there is no feature for this in Fusion 360.

Although these are technically circles, not holes.

You might want to use Hole features rather than sketched circles depending on your true Design Intent.

I realise that I called my circles for holes which is of course wrong. However I am still a novice at this and I called them holes as they are going to be holes eventually. I know of the hole command but have also been told that a well thought out sketch is an effective way of making a design (e.g. changing the sketch dimensions will automatically make features adapt).

Also I should have said that this is for 3D-printing.

Thx for rapid help!.

Did you catch what @TheCADWhisperer said about design intent? that may change how you approach this. what is the end result you are looking for? ie what will you do with this, what function does it have?

right now you have a consistent distance between the centers, are you sure you wouldn't rather have a consistent distance between the circumference of the circles?

It's going to be a block with different sized holes. The holes will be for axels.

So it's not crucial with distances between the holes (circles) but design wise I would like it to look nice. I'd rather have consistent distance between the circumference of the circles but for now I wanted to start with the centres.

I definitely started out wrong but I´ll have a go with the centres aligned with consistent distance.

I did watch a tutorial regarding constraints and I understand a lot is possible but as of now I don't have the skills/experience to take advantage of them.

@kzycek

i started to give that solution too, but then got lazy.

The way I would do it is with Equal Constraints lines between the circle circumferences.

I´ll try to play around with this as it's for sure a good exercise.

No construction lines or rectangular patterns necessary. Use horizontal constraints and dimensions (either center to center or tangent to tangent):
