Hello

Can i get some help with this project?

I need to build a reprocal structure, now using ngon

I cannot seen to get the correct joint between the rectangular elements

I am using region slits, but after applying it´s thickness, i do not the correct difference angle.

Any ideas?

Because region slits will not give you true notches, only rectangular ones. If true slits are needed, then you need to make them.

Also, it’s best if you post a screenshot of the problem.

Hello Rene

Thanks for your reply.

What you described is exactly what is going on

You can see in the see in the image that the notches do not align

Could you hel me how to generate them?

Best

Did you try using Box Slits instead?

Sorry, I just corrected the question: I meant BOX slits! :sweat_smile:

*Also, some people might not have the plug-ins you’re using, so I recommend you internalize the objects in question, using a geometry or data component:

Another route to explore (searching the form) is “waffle” structures.

They emphasize the slots to connect pieces rather than reciprocal structures but you might find some inspiration?
