Can you please send the data containing the 2 geometries only. I will write a piece of code to try to repro the problem.

Are the shaper geometry and edit geometry simple?

‎07-25-2013

Without seeing the actual data and code, I can only take a guess on the cause of the problem. The error message should be "The coordinates or measures are out of bounds." rather than the other one you mentioned, NETWORK_E_EDIT_SESSION_IN_PROGRESS. The error code associated with this error message can be returned from various places in ArcGIS library. In addition to check the feature geometry's location in the coordinate system, the attributes measurement such as Z and M is also considered as the possible cause here. Also, if the geometry involves curve segment, like bezier, clothid, etc., can sometimes also causes this problem during the process.

I'd use esriGeometry2Dimension as I metntioned before to get the polygon output. ESRI.ArcGIS.Geometry.IPolygon pPoly = pTopoOp2.Intersect(pPolygon2, ESRI.ArcGIS.Geometry.esriGeometryDimension.esriGeometry2Dimension) as IPolygon; Then I will use ISegmentCollection ISegmentCollection pSegColl = pPoly as ISegmentCollection int count = pSegColl.SegmentCount for(int i = 0; i<count; i++) { ISegment pSeg = pSegColl(i); //Do whatever you want with it } You can create a segment collection of polyline type ISegmentCollection pSegColl2 = new Polyline() as ISegmentCollection and then add all the segment from the pSegColl to pSegColl2. I didn't check the syntax of the code, but you got the idea.

No problem. I will try my best to help. First you need to get the polygon feature class, and a shape (a polygon or an envelope I assume) as input in your code. We can then start from there. What programming language you use?

‎07-16-2013

Use ITopologicalOperator::Intersect with output option set to esriGeometry2Dimension, you get a polygon, and then cast to ISegmentCollection. All the segments in this collection will be within the shape.

I will use ISpatialFilter to get the polygons. For each polygon, cast from IPolygon to ISegmentCollection interface, you get the segments that you want.

In ArcObject, there are IZAware and IMAware interfaces, you can call DropZs and DropMs to reset the Z values and M values, or set ZAware or MAware properties to false. These do not apply to feature class, so you have to go through each feature and get the geometry. http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#/IZAware_Interface/002m00000442000000/ http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#/IMAware_Interface/002m0000022t000000/
