Grasshopper Tutorial (Celtic Knot)

[@ParametricHouse]

In this Grasshopper tutorial, we are going to model a parametric Celtic repeating pattern. First, we are going to explain how we can model the base module and then we are going to make a triangular grid, use list item to choose the right corners, make circles with the same radius and then use the region difference to produce the base module. Then we will use a triangular grid to orient the base module on it and finish the tutorial.

awesome tutorials. love the way you explain everything

[@totalmentekemado]

I really love your tutorials. They are well explained and not boring at all... Awesome work. Thank you for taking the time to share.

[@ParametricHouse]

You're welcome😊 glad to hear that

Lots of tutorials all over KZbin but really very rare are able to explain the way u do. Sketching what u will do before going through grasshopper process ( really amazing) , u have amazing way to explain things, thanks for your efforts. Soon will take your online course.

[@ParametricHouse]

Thanks Wael🙏glad that it helped

[@fadeelhusin4517]

Great explanation. I liked your way of thinking of how to reverse the whole pattern to its starting steps. Great efforts.

[@ParametricHouse]

Thanks🙏

Hi, nice tutorials, thanks. Starting from minute 8:16, we could've used the two Circle components with one Region Difference to achieve the same result instead of creating 3 Region Difference components in addition to the List Item component at minute 8:18

You could make a remapping of a slider from 0 to 1 to a domain from size of cell divided by square root of 3 to square root of 0.75 times size of cell. A bit of math but than you have a cleaner control over the pattern.

[@ParametricHouse]

Correct! Remapping is also another option👍

Thank you. How do I save it and use it in the design of gold and jewelry؟?

[@architectq9798]

Any reason youre not using a hexagonal grid in the beginning to generate your points? Without having tried it myself, it seems easier since you dont need to cull duplicates.

[@ParametricHouse]

You can also use a hexagon but you have to dispatch the corners to only use 3 of them. Anyway this can also be done by polar arraying a point or any other method

[@arsenjohnbosco2629]

Thanks for the nice illustration....Apart from contoling the minimum and maximum sizes of the pattern by slider, could a logical condition be added to control its size ?

[@ParametricHouse]

Yes it can be easily done. Connect an evaluate component to the slider and give it conditional statement for example if(x

[@chandrasekaran2429]

nice work sir ...... any alternative .... method is available?

[@ParametricHouse]

I also explained an alternative method in the video but anyway you can also give the pattern more control by focusing on smaller parts of the module and give it multiple parameters

@@ParametricHouse sir i got it need to start different way... and than finish... but i like your grasshopper explanation. and standard detail so helpful.... long days back i'm started this grasshopper. thank you

You're welcome

how do I turn this geometry into a 3D interlaced surface?

[@ParametricHouse]

You can somehow morph this on a NURBS surface but it's going to be more complicated for any 3d model

[@yaraahmed2923]

how could i make it in 3d ?

[@ParametricHouse]

You can also use orient to make a series of 3d modules

Thank you. How do I save it and use it to design gold and jewelry on surfaces?
