Division limits

hi ... i don't know if this is possible to do with grasshopper but here it goes..

i want to divide a surface... easy part.. but i want that division to have a limit... and by limit i mean that when i move the slider i want it to stop me when the division makes surfaces less than 15 cm... is that possible... ??? i'm just starting to use this program and i'm loving it but theres much i have to learn...

i want to put that limit so then i can apply it to different surfaces...

thanks for reading hope theres a way to my problem... =)

Unless you can work out from first principles what the maximum division count could be, there's no way to directly limit it. You'll have to divide at least once, so you can measure whether or not the division exceeded the limit.

I think an easier approach is to measure the distance and display a warning when objects get too small.

thanks for the help =)

is there a way to get the dimension of the 4 sides of the surface... so when it gets the factor m, its including all sides of the shape..

Yes you can extract both edges and isocurves from a surface, and measure their lengths. However note that you're creating surface strips by cutting up the UV space of a surface, which is not guaranteed to progress linearly between the two limits. It may well be that if you divide a surface with domain (0 to 10) into ten strips, you end up with strips that have physical dimensions like (5, 2, 1, 1, 1, 1, 1, 1, 2, 5), rather than all being the same.

thanks again =)

i did it using the surface edges instead of the dimension surface..

and then used the factor you gave me
