Assuming the intent is for the lines to intersect cleanly: Example A is called an Overshoot. Example B is an Undershoot. Chris Donohue, GISP ... View more

Less likely, but worth checking if all else fails- check if your data and Data Frame all have a coordinate reference system applied.  If some do not, they can change unexpectedly as you zoom in and out. Chris Donohue, GISP ... View more

If the data is in a line feature class and there is a field attributed by material type, one can run a Dissolve specifying the material type field as the dissolve field to create a layer with lines with consistent material.  This dissolved feature class can then be symbolized by Material type to spot the changes.  Alternately, if one has an Advanced ArcGIS license level, one can run Feature Vertices to Points on the Dissolved feature class, specifying Both Ends , to create a point layer which can then be symbolized to show the change locations. ArcGIS Help (10.2, 10.2.1, and 10.2.2) - Dissolve (Data Managment) Feature Vertices To Points—Data Management toolbox | ArcGIS Desktop  Note that this assumes the data is coincident, i.e. pipe segment ends touch each other cleanly (no gap or overlap).  If the pipe segments are not coincident, you will need to employ Topology and Editing to make their ends coincident.

I don't know for sure on that one.  My SDE Administrator found that there were variations on the storage types not only based on what was specified but also what the Database is (in our case SQL Server), what version of database, and even in some cases what patches were applied.  It would probably take some digging to figure it out. In regards to the issue you are trying to resolve, I wonder if there would be a way to take your data, irregardless of whether it is in a true curve or not, and process it to make true curves (like into a File Geodatabase).  Just pondering, but that would then allow running the model. Also, let me tag a specific group.https://community.esri.com/community/transportation . They may know of a different approach to do the analysis. Chris Donohue, GISP ... View more

One caution, SDE supports several geometry types, but some of them do not support true curves.  We recently discovered this when we were considering moving to a different geometry type for some our feature classes in SDE for performance reasons. Also, for other readers that are interested, I believe this is the model being used: http://www.arcgis.com/home/item.html?id=267ce9c896a5480982cfa4bfa1747018 - Identify True Curves Chris Donohue, GISP ...

File geodatabases do support true curves.  However, of course, the depends on how the data got into the File Geodatabase.  If someone imports a shapefile into a File Geodatabase, it does not change the "curves" to true curves; they still remain many small straight lines.

I don't know the specifics on the model mentioned but one possibility to bring up - it may be that the input data does not have the true curves it is looking for.  For example, if the input data was from a shapefile, none of the features in it would be a true curve, as shapefiles do not support true curves (shapefiles form a curve by using very short straight lines instead).  So getting a warning that an empty output was generated would technically be correct. I'd run a test feature class that has a mix of true curves and densified curves to see how the model responds.  Also, it may be that the model is set up to do something different than what you want.

I'm not sure what version you have of ArcMap, but here's the ArcGIS 10.1 instructions.  If it is not 10.1, check the Help for similar topics as there may be changes between 10.1 and other versions.

There are several places where things can go awry.  Here's a good article with a process which helps one avoid the common issues.  I'd run through this process.  If it doesn't work out, let us know what went awry.

.AVX files were used with ArcView 3.x.  I don't know offhand if they can be used in modern ArcGIS versions. avx - ArcView extension file (ODB format) source:  FAQ: What are all the file extensions related to ArcView?  Also, I have heard that the site you downloaded the program from has not been updated lately for recent versions of ArcGIS, as the proprietor is concentrating on other projects. rastrauch  Chris Donohue, GISP ...

In the original map, something to check would be to see if any of the Annotation setting(s) are not checked on.  Sometimes these get turned off, which means when graphics are attempted to be added they "disippear", when in fact with this setting unchecked they are getting added but not displayed.  Note that there could be several annotation groups listed here (the example below just has the normal default).  If any of the groups listed here have the checkboxes off, turn the checkbox on and then see if you can then add Graphics.

If the issue is that the tool is failing to move to the correct location, I'd start by checking that your Data Frame and data layers have a coordinate system. Also, check the section "Guidelines for specifying coordinates with the Go To XY command" in the tool Help (see link below) for the particulars on how the tool expects the data format to be when entered into the tool. Using the Go To XY tool—Help | ArcGIS for Desktop  If the issue instead is that it does go to the correct location, but you are unable to add a point or callout, we'll need a bit more information.  Is the goal to add a point as a Graphic?  Or add a point as a feature  in a layer?  Also, when you are attempting this, are you in Data View or Layout View?

Robert Scheitlin, GISP has the easiest answer.  Modelbuilder is very useful, it a bit quirky to figure out at first. I will also add that the batch process can also be done using Python if you are familiar with it.
