Just thinking off the top of my head here but could you have a very simply text file which lists paths to other locations and include that into the AddIn. Then your AddIn code looks for this file and reads from it allowing you to store your data elsewhere? I have not used Python AddIns so not sure how easy it would be to include a separate file?

If your source dataset has ZM values (even if they are not set) and you want to drop these from the entire dataset you will have to export the dataset to a new FeatureClass which does not support ZM values. If you want to achieve this in ArcObjects the easiest way is probably to call the geo-processing tool using the execute method on the IGeoProcessor object.

You would need to create a FeatureSet in your model, expose as parameter, ensure schema is set to any old polygon layer, then when you OPEN the model from toolbox you have an iteractive method for selection features. See attached image.

Your calculate expression is invalid, you have: "[Shape_Length * 2] / [Join_Count]" it should be: "[Shape_Length] * 2 / [Join_Count]" Duncan

Shiko, Sounds like you want to be using FeatureSets, have a look here. Duncan

Accessing the point collection using an index makes a lot of sense to me but I totally agree the Help for this method is about as clear as mud. ESRI need to improve this with proper examples.

The answer to your question is here. I would also question the wisdom of any dataset with 650 columns...

I found this bit of C code on the ESRI website, midPoints is a IPointCollection pointer object before = 0 as object; midPoints.AddPoint(m_curve.FromPoint, ref before, ref missing);

Another approach is to: Extract the end points create XY fields concatenate xy field into a string field do a summary stats on string field, this gives you the valency of the node (how many polylines attached to it) join table back to node featureclass and label with valency Duncan

Andrew, Sounds like you want to be hooking into the IActiveViewEvents Interface and capture when the map changes in someway. Duncan

Sounds like the source workspace is corrupt. Is your workspace an Access database or a personal geodatabase? I would use arcmap to create a new geodatabase then copy your data into it to ensure the GDB_ tables exist.

Carsten, I'm guessing the error is occurring because your candidate is pointing to a path class which is a sequence of connected segments, try a polyline class? Duncan
