Yes, My GCS and import fields are set correctly .  Do I assume because the GCS is a lat-long format by definition, then the program knows to import in that same format ? ... View more

Dan, Yes indeed, thanks for that feedback.  The 3d polyline was adjusted in its Z value using the Adjust 3DZ function.  However, the change was not obvious in ArcMap.  I did not see in the attribute table or the properties of the object in ArcMap, having different units or Z values.  But the Z value change was observable in CAD.  Is it possible to confirm the change in ArcMap ? ...

Yes, thank you, I used Field4*0.3048 which gave the correct results.  I suppose if I had linework that I needed to adjust the Z value for, then the Adjust 3D Z method is the preferred way ? ... View more

Dan, I see what you are saying.  I selected in Arc Toolbox->Data Management Tools->Feature Class->Features->Adjust 3D Z.  I did not see an obvious change but did get a successful response that the adjustment was made.  Since I am working with points in attribute tables, I think you said the above process will not work for tables but I can use the Field Calculator to calculate the metric units in a new or un-used column of the attribute table.  Please confirm if I am now understanding or if there is still some part I may be missing. ...

Curtis, Thanks for forwarding to the proper forum, I was unfamiliar.  Will look forward to their responses. ... View more

Dan, The example involves python programming which I am not familiar, unfortunately.  I did try to copy and paste the lines of code into the python window but got an error on line 1.  But if the transformation/projection is complete in every other way, it is just a matter of converting the Z units to meters in excel, if I am understanding correctly. ...

Dan, Yes, I believe per the screen shot below, that the Z-Values are true.  If I understand, those are turned on or off using the Environments tab in the Transformation of Project, set as "Same as Input".  Is my understanding correct? ... View more

Dan, Thanks for that feedback.  So if I understand correctly, the actual units will not update,  but the Z-Coordinate I selected will update which proves to be the case per my example project.  If I "transform from a state plane system such as NAD83, to a geographic system such as wgs84, that involves both a transformation and a projection.  Am I correct to assume that is the case ? ...

Dan, In arc catalog I created a file database, then imported my points into the database as a feature class.  Then I ensured the feature class had a Z coordinate to start with (NAVD88).  Then I performed the transformation/projection from NAD83 Intl Feet to WGS84 meters.  The XY appeared to change properly to WGS84 but the Z values were still showing feet values.  What am I likely doing wrong if I want to get meters as my Z values, assuming it is possible? ...

Dan, Ok, if I understand, my project tab "Z Coordinate System" found when populate Output Coordinate System (see screen shot below), is the same as the "Vertical Parameter Button" you are referring ?  If I am correct, my elevation values are not changing from feet to meters.  I have an elevation, for example of 25.36', that value persists after the transformation (SC Nad83 Intl ft to WGS84 m).  What else am I likely missing ? ...

Dan, I am not getting the Vertical Parameter button.  Below is a screen capture of my project dialog for reference.  Perhaps I am missing something or do not have the correct version of ArcMap ? ... View more
