work with intersection point of the lines

DenEsenal

hi everybody,
I am new to ArcObjects and looking to get some ideas.

There are several polyline and point features in GDB.
Need to add point to an existing point feature class. Point formed at the intersection of the lines
How to do this in the process of drawing a polyline?

Thanks in Advance.

So you have your feature class, say featCls
IFeature feat = featCls.CreateFeature
feat.Shape = point //point is the intersection of the pplyline
feat.Store()

That's it, you just added the point to your feature class.

Hi Den,

I am not aware how to add the intersection point while drawing polyline. However, below is the link for sample code to create point where polyline intersect. It is a VBA code You may need to modify the code as per your requirements.
