Honeycomb pattern from a parent sketch.

Anonymous — Thu, 02 Aug 2018 13:52:10 GMT

I'm super new to Fusion 360 so im not all familiar with the terminologies but here goes.

As a learning process im trying to re-create something similar to this:

https://www.thingiverse.com/thing:2559624

But I want to create a single comb and constraint the other combs to have the exact same dimensions but be attached to different points. The idea is to be able to duplicate a body and create some random pattern but where all combs gets their dimensions from a "parent" comb.

So if I wanted to change the size of the wall of a comb or the height after extruding all other combs would get those dimensions as well.

Attached a few screenshots of what im trying to do.

Thanks.

Pattern Features, Bodies or Components, not sketch elements.

Do you know how to fully define just one - just a single hexagon?

That is the start.

Extrude and Shell will then be tools that you want to research.

Going through the Tutorials would help you make good progress towards your goal.

But if you are just excited about getting this project then, File>Export and then Attach your *.f3d attempt here.

Im able to build a singular comb - attached here - but im not sure how I would use that in a "Pattern Feature" so that if I make changes to the "Parent" all other bodies will inherit those changes. If that makes sense?

Also if I play around with patterns they seem to be exactly that; a pattern. But if I want to randomly build that pattern (as in the link to Thingiverse) can I use a pattern still?

What is the purpose of your Extrude3?

Wouldn't it be easier to simply Edit Extrude2?

or Shell?

Your Sketch1 is missing a Horizontal Constraint?

If you want random - then move/copy body/component to desired location.

Any sketch/feature can be edited during or AFTER creation.

I guess so, I just wanted to be able to change the thickness of the shell afterwards.

Thank you so much - I learned a ton of stuff from that screencast!! That was exactly what I was after.

Just out of curiosity; is it possible to have a parent/child relationship between components or bodies? In Blender there is the concept of a "shallow duplicate" or an actual duplicate where it maintains it's "parents" mesh properties meaning that if I manipulate the parent, all child bodies/components change as well.

It seems like what you are doing here with parameters most likely is as close as I get?

Thanks!

Sort of, yes.

You can nest components within the hierarchy of the Browser. You can Copy>Paste Components, which will create a linked duplicate. Or you can Copy>Paste New Components, which will create a non-linked, separately editable ones.

Please note:

The way I did things in the previous video has each hex as a Component. This is ideal if you are going to, for example, 3D print individual hexes and glue them together.

If you want to 3D print the whole thing as a unit, you'll want it to be one contiguous body. See the vid below to see how I get both the "separated" versions and a "combined" version in different Componenets. You can choose either 3D print method now. And because of the way I did it and the order I did it in, the "combined" version always copies the "separated" versions, except that it doesn't have any separation of course. It's all one Body. If you added another hex in the "separated" version, of course you would want to first roll back the timeline to when it was set up to do so, and then roll back the timeline to when you were copying its Bodies into the "combined" version and copy that new one as well, and finally edit the Combine item and include that new body also. It's very sensibly organized if you think about it.
