SDivide gives me two 0s and two 1s, instead of 0,1,2,3

Want to draw a line from one corner to the other in a subsurface i have, i divide the srf in 1U and 1V, so i could get the four points P and draw the line using "list item" to get the points; but SDivide outputs four points grouped in two items, 0 and 1.

how can i get the four points listed as 0,1,2,3 ?

thanks. Dani

Hi Dani,

why not evaluate the (reparameterized) subsurfaces at {0,0} and {1,1} ?

didnt work, re-evaluate, and same result, n=2 instead of n=4, i will keep trying.

You'll need to check the Reparameterize option in the S input of SrfEval. This will force the domains of all surfaces to {0;1} {0;1} in both U and V.

Subsurfaces are now reparameterized and grafted. Using Eval Srf to get the corners instead of Divide Srf.

still not working.

i divide surface in 1U and 1V, but i get uv n=2 instead of n=4, i need n=4 to define one line with 0 and 2 uv item...

did you try flattening? i havent tried it but i heard that in the new versions of GH that the sdivide command was a little different. ive read that flattening can help with this
