polygon split

[wateryfield]

Hi, guys.

I get a problem maybe it was be asked before, but i can't find any tips.

There is a grid polygon and i add a line on it by add SOP.  Is it any way split the grid to two part by the line even the vertex number was not right.

I can split it by polySplit or Clip, Break SOP, but they were not flexible enough.

Any help will be appreciated!

Thanks.

I think you have to write some Python expression for PolySplit SOP to generate the points you want split unless the point numbers to split is fixed.

I think the expression was a great way to do it, i will take a try.

Since i not good at python, i look forward someone have a simply way to achieve it.

first thought.

1.create a transform and center the grid to the cplane Y

2.create a transform to set the grid parallel to the construction plane Y(if needed)

3.us 2 deletesop extraction left and rightside using >$TX and $TX.

4.add the line in both extraction and use a join sop.for each output.

5.merge them back

 

not so elegant but i think that will give you 2 primitive with the line the center line atop of each other

Thank you. Willow.

It was feasible, but i think it not not flexible enough.

Actually i want split many parts in a SOP once, it seems the polysplit with expression was the best solution.

the fuse sop has the ability to create unique points in a given group, that may work on splitting, rather than the polysplit

your last resort may be the cookie sop
