Loft less curve with more curves

Hi,

I have problem with loft two sets of curves, that have different counts.

One set of curve is from the division of "vault" (from flip of the quarter unit).

The other set of curve if from the division of the vault bottom surface, has less division curves than the vault.

I need to loft the curve from bottom with the curve from vault. But only get the original quarter vault connect to the bottom. (as the gh. file shows now)

Can someone tell me how to relate the bottom to every quarter unit, and loft the curves on them with the bottom curves;

And how to control the items number, so I can switch the loft [1] on bottom with [2]/[3]/[4].. on the vault?

Thank you very much!!

Hi Heinrich,

Thank you very much for the reply! That helps a lot!

For the order, it relates one curve from bottom with the quarter units at the same spot now. (Shows in picture) Is there a way to connect the one curve on bottom with other spot, so the number of item is all switches like:

1, 2

2, 3

3, 4

4, 5

5, 1

Another question is, if I have more division numbers on the vault(I mean a quarter unit) than on the bottom, can I still loft the curve from bottom with all the curves on the vault?

Regards.

Hi Heinrich,

Thank you very much for reply. It works very well.

But I just found the curves from vault are not really attach to the surface, because they are from the "diamond" planer curves. I tried to project the curves on surface and follow the scrip you gave me, but it doesn't work as the original way. ( please see the attachment)

Can you please help me take a look to see what's wrong with it?

Regards,

Yuge

Hello Yuge

You need to do the following

Trim tree changes the curves tree to have 4 branches (lists) with 8 curves each branch. that matches the data structure of the vault 4 surfaces, after being grafted and simplified, so that you have the same path structure between them. that way each list with 8 curves gets projected to the corresponding vault surface.

cheers

ps it is essential to study lists and trees to work easy with grasshopper
