is ITopologicalOperator.Intersect can used in 3Dimension？

i got an argument exception，when set esriGeometry3Dimension

thanks a lot

do you see the graphic in the link to the documentation for ITopologicalOperator.Intersect?

I guess the example with the two lines shows the solution for your problem... or i don't get it

zszs

thanks for your reply，actually，it is not the intersection

i mean，some parts of two line，in the spatial，are almost same

i need get the same part
