hello joe!!
thanks for your help.
Maybe i didn't explain what i need. sometimes my english is not good.
i have a function for getting the centroid of polygon, like the application
you sent me, but i don't create a region.
i just sum x and y coordinates and i get the centroide.
what a really need is, for example in an irregular polygon like an L, the
centroid is outside of it.
i need the centroid always inside. i don't know if i'm talking about
centroid and this is wrong.
do you know Autocad Map?? have you created topologies?? i need the point
like autocad map puts the centroid.
or like arcinfo the same.
thanks very much for your time.
I develope applications in AutoCad and AutoCad Map, working with topologies,
object data, databases etc.
basically GIS, and sometimes i have 50000 polygons for processing.
if i can help you anytime i'm here!!
