Project Help / Suggestion

Hello All,

I am currently designing a mold to create a slip cover for my design portfolio. I am new to grasshopper and developing an algorithm to achieve what is displayed below. Attached are images of the actual cover, a concept sketch, and a 3d model I started to work on in Rhino.

I need a way for grasshopper to generate points on the lines drawn based on the proximity of the contiguous line above it. I will then use the same algorithm to determine the radius of a sphere centered on said points. What this will generate (hopefully) is a 3D surface based on 2D contours. The measurement between lines will have to be perpendicular to the point on the line to determine the correct radius.

Any suggestions on how to approach this project would greatly help. Please contact me at amalchemydesign@gmail.com .

Thank you

Hey,

maybe this is a point to start from. The inputCrvs can be easier by a cull pattern. (then you can read all at onece).

The Cover is pretty difficult and not so easy to handel. There are many "if" situations in it. the skecth you made would be much easier. :-)

Hey,

Thank you for your suggestion. I will try this method when the algorithm is all worked out.

I appreciate it.

Best,

Sean

hi dedackel,

do you know how to create parametric curves, as in the example above.

or something like this:

thanks in advance

hehe,

somthing simillar.

The main trick is to define a increasing/decreasing value for the rotation, the influence area is easy to define.

hi michael,

why dedackel laughs? (:
even if he laughs, thanks anyway.

and many thanks to dedackel.

something else, i would like to know,
if is it also possible to attach multiple points
with your definition?

I dont know why he laughs, I only proposed a start not a solution, I literally did that in 5 seconds at work.

I laughed because my 5 secounds work was quiet the same as yours! :-)

guys,

i think the story is complicated for me.
it is a matter between you.
i consider myself out of there. (:

dedackel, can you affect the curves also in the z direction?

dedackel,

sorry, i forgot: i like it!
