Having hard time making array of hex shapes?

[Anonymous]

Why is it so hard to sketch a simple array of hex shapes( like a bee comb)? Not that many cells just 19.

Also trying to do it para-metrically with just two parameters. 

I keep getting over constrained errors, when there are still lots of blue lines not constrained.

I could do it in Sketchup a lot easier, but I can not see an easy way then to convert it to be parametric.

How about one user parameter, a couple of mirrors, plus a couple of circular arrays?

Hi,

Even though there is no problem with this amount in sketch mode, I would like to point out to create arrays only in Body/Face mode. In the sketch only 2 hexagonal elements are needed.
Especially with honeycomb arrays you can quickly get over 500.

Then the fusion sketch solver is at the limit of its possibilities, if it has not already exceeded them.

As indicated by @g-andresen  you should pattern bodies or features.

File>Export and then Attach your *.f3d file here if you can't figure it out.

An image of your ultimate Design Intent might be useful as well.

Like this, done in Sketchup, except with parameters cellradius and cellspacing.

Sketchup is Ok, but this is a Fusion 360 forum 😀  Where are you having trouble doing this in Fusion 360?

This was done with just one parameter with several joints and a couple of circular patterns.  It's not a difficult task if you think in Fusion 360 terms instead of Sketchup terms.

Me mentioning Sketchup was the fastest way to describe what I needed to do, since Fusion 360 was mot working for me. Can you show me how much of this you did in a sketch and how much was generated outside the sketch? That is probably what I am not used to doing. I do need the 2 parameters to control both the size of the hex and the spacing between them.

Attached is a file with a couple of ideas.  many other ways to approach of course.  take a looks see and let us know if yo have questions.

and a screen cast also-

Very efficient! This is a nice way of doing it.

Here's one way to do it with joints.  To do it in a sketch, then you can just copy/paste the three hexagons needed for the circular array, however, when it comes time to extrude, you'll either need to do a lot of trimming or selecting small closed boundaries.

Here it is with just a sketch.  It is rather tedious to add all the necessary constraints to make it parametric.  Still only 2 parameters, one for the size of the hexagon and one for the wall width.

Thanks for your solutions.

I have learned a lot from your examples and especially like the  last one.

I guess the circular copy must take up less processing for fusion to keep track of.

When I used axial copies it seemed to get bogged down computationally.

 look forward to recreating it on my own soon.

Thanks again
