Distance and Direction holds on to previous coordinate system, bad results

[BobBooth]

• If you open ArcMap
• open Distance and Direction add-in
• add a basemap (sets the data frame to Web Mercator)
• change the data frame to WGS84,

the add-in seems to be mis-handling the current coordinate system for line construction.

• Create a line interactively.
• Add two points in different hemispheres.
• The line is labeled plausibly, but the resulting feature is invisible unless you zoom in many times to the center of the label.
  Using the ArcMap measure tool, the distance I got in my test case is 171 meters.
  

ArcMap 10.6.0.8321
DD 2.2.0.26

@csmoore @kgonzago - I just found this while setting up to do a checklist test for #503
I feel like I've seen this before, but didn't see it in the issues.

[csmoore]

@BobBooth - you are correct this is a previous/known issue (with all of the addins) - recorded here: Esri/visibility-addin-dotnet#248 - but a good time to see if there is any progress on this

[BobBooth]

@csmoore - thanks, I didn't think to look in Visibility.

If you set the coordinate system to WGS84 before adding the basemap, the tool works as expected.

We need to understand if this happens with LInes, Circles, Ellipses and Rings.

This challenge could be related to how we are creating the graphics containers during the interactive selection. I think that we are placing the spatial reference on these points during that initial graphics creation. If we can update this spatial reference when the map changes it could be the fix.

Steps to replicate:
Open a new ArcMap session
Add a basemap (Web Aux Sphere is the projection)
Create a line using interactive
Change the dataframe coordinate system to GCS 1984
Draw another line
Result
Graphics do not show up on the map if the element is saved to a database object (feature class or shape file it is created successfully)

Possible Solution
When the spatial reference is created the graphics container that we are creating needs to be deleted and a new container needs to be created to allow the graphics to be drawn correctly.

@saip I am able to replicate this issue with ArcMap 10.7 and ArcMap 10.6.1

Currently multiple users are not able to replicate this issue. @lfunkhouser can you take a closer 👀

This appears to be working correctly now. Tested switching between Web Mercator and WGS84 Geographic, was able to draw lines, circles, ellipses in ArcMap 10.3.1 with the 1/7/19 build of Military Tools.

Tested on 10.6.0 (with the 1/7/19 build of Military Tools) and the problem still exists.
Repro steps:

1. Open ArcMap (10.6).
2. Open Distance and Direction (from recent build of Military Tools).
3. Add a basemap to ArcMap. Dataframe will be set to Web Mercator.
4. Draw some lines from Points, interactively.
   
5. Open the Data Frame Properties and switch to WGS84.
   
6. Draw some more lines. Notice that the feedback line appears, but there is no apparent output.
   However, a green dot and label will appear off the coast of Africa (at 0,0).
   

This also affects the Circle, Ellipse, and Rings tabs.

Add workaround documentation for 10.5.1-10.6.1 for this release. Issue will be addressed for next release.

[BobBooth]

Added workaround sentence to DD and MT Resources doc.

[BobBooth]

Moving from In Progress to March release backlog, because the work-around instructions have been added to the doc for January release. We will look at fixing the actual problem in 10.5.1+ in the March release.

This issue is resolved with the released addin on 10.7.1.

This issue was similar to Esri/visibility-addin-dotnet#327 ,
Esri/visibility-addin-dotnet#327 (comment) but no changes were needed to the D&D addin.

Note: from 10.5.1-10.7 - this is a know SDK issue: Esri/arcobjects-sdk-community-samples#7
