Structure of Honeycomb in CATIA v5 step-by-step? 1

[zgrgrz]

Hello guys

Could anyone help me or explain how to create Honeycomb structure in CATIA? I need to create a big honeycomb but always I can't go further than few rows. The best idea is to create one honeycomb and copy them but I totally do not know how to do that in CATIA v5, I tried mirror option etc but it does not work well. I attached photo how it should look like. If anyone has any idea please help me Thank you in advance!

Use a "rectangular pattern" or "user pattern" found under Part Design workbench > Insert > Transformation features.

@drewmumaw It does not work, It is easy to do one structure or five but its almost impossible to make more... Like make one big honeycomb!

It works for me. See screen grab below of my history tree.

Looking closely at the lower-left corner, I see Drew sketched two hexagons for the first pad. He was able to make a Rectangular Pattern in the Horizontal and Vertical directions. That's pretty clever!

To get the same result, I would have made a single hexagon sketch, and patterned it in the Horizontal and 60° directions to get the bottom two rows, and then add a second pattern to go vertical for the other rows.

Thank you guys for you help but I still can't do that. I posted few pictures step-by-step how I am doing this and when I have a problem but someone deleted this and change my post (Weird) and my password has been changed, I do not know what happened :O

@grzenio23
Since jackk and I were both able to create a hex pattern, I think this is an error on your side (along with the eng-tips.com site issues that you're experiencing).

Here's a few tips and things to check:
[ul]
[li]Remember to only sketch the outline of the hexes in your sketch.[/li]
[li]Fully constrain your sketch (the geometry should turn green)[/li]
[li]When creating the pad, use the "thick" option if you want a solid result with thickness.[/li]
[li]When uploading your step-by-step images to this site use the image icon with the plus symbol above the input text box.[/li]
[/ul]

@drewmumaw
Thank you for your message. Yes I know that error is on my side. I posted how I am doing this step-by-step and the 4th step is my main problem, do not know how to do that equally and symmetrically like you guys did, if you have some time please have a look
Thank you in advance!

Select one of the planes for your "reference direction".

@drewmumaw
Thank you for your message. I did it with reference direction but is there any chance to leave all walls with the same thickness?

 

[drewmumaw]

@grzenio23
Thickness can be modified in the parameters of the pad feature.

@drewmumaw Thank you but I did this. I mean, thickness when I am doing Rectangularn Pattern, is it possible to make "new honeycombs" stick to "old honeycombs" perfectly? With no gap or double-walls etc?

 

[drewmumaw]

@grzenio23
You can decide which side of the hex profile to have the pad feature create the thickness. The rest should just be a matter of calculating the math to make it work as desired.

Any time! Glad you got it to work. btw..what are you designing? a heat sink?

@drewmumaw I am designing just Honeycomb Cores, I have to compare different materials etc to make it cheap to produce, good to work Its part of my coursework, have to write 5000 words report about Honeycomb Cores

there are not too much types of HC. hexagonal, over expanded and flexcore.do a search and you'll find what is cheaper to produce.
