In ArcObjects there is the IZAware interface we can use to make an existing 2D geometry aware of Z-values.   I can't find the equivalent in the ArcGIS Pro SDK -- but there must be a way to do this.  How can I, for example, change a polyline that may include a parametric curve from a 2D polyline to a 3D polyline? ...

This may seem like ancient history, but I'm looking for a way to convert an Arc/Info Workstation IGL Font to a TrueType font that can be used by ArcMap.   I had thought there was a way to do this, but can't seem to find any either via Google search or here.  Any pointers would be much appreciated.

Is there a way to read records from a many-to-many relationship table from Arc Python? Thx, Ed ... View more

Hi - Am trying to append the contents of an M-N relationship table in one Geodatabase to an identical table in another Geodatabase using Python.  I had thought that since there is a table that holds foreign keys for the related features that an Arc Python APPEND would work as it does with other tables.  But apparently not so. The code is basically this: classes = ["RelClassName1","RelClassName2"] for className in classes:     arcpy.Append_management(class, os.path.join(outputWorkspace, className), "TEST") If the classes are actually tables this works fine.  If they are m-n relationship class names it doesn't. Any suggestions would be much appreciated. Thx, Ed ... View more

Hi – I’ve got a file geodatabase with lines, points and feature-linked annotation.  For creating new annotation features I’m using the “Selection | Annotate Selected Features” tool from the ArcMap table of contents.  Always for a single selected feature at a time.  Sometimes this can be quick, like a second or two, but often it’s slow, taking 30 to 45 seconds to annotate a single feature. The process brings up a dialog that describes steps:   - Setting up annotation   -  Giving features to the label engine   -  Labeling features   -  Creating the annotation elements When it’s slow it seems to pause at the step “Giving features to the label engine”.   The target annotation class doesn’t really have a complex expression.  It is usually getting a value from a single field.  I’ve tried with and without a feature cache built – no difference. I also found a reference in Geo.Net back in 2014 that reported an issue with a corrupted group layer. (https://community.esri.com/message/95014).   So I tried creating a new map with only the source feature layer and related anno layer.  Still slow. A thing I *did* do that make be a clue is change the annotation expression from one that used JavaScript to one that uses VBScript.  The two expressions produced the same text string.  Not sure if this would make a difference. Any pointers on why this step would take so long and what I can do to improve it would be much appreciated. Thanks, Ed ... View more

Hello – Working through the UN Electric model and notice that “normal position” of switchable devices is a property of the ElectricDistributionDevice – which is considered “Content” within an ElectricDistributionAssembly “Container”.    Given that the assembly (rather than the contained device(s)) will be displayed for most purposes, and does not contain a “normal position” attribute what is the generally recommended approach to symbolize switchable devices based on their position? Thanks for any pointers. Ed ... View more
