"Tentative Point Annotation and Vertex Elevation Modification Provides Significant Productivity Improvements"

 

            In engineering site design, features of interest are often annotated with their Easting/Northing coordinate location.  In MicroStation, this coordinate location can be obtained by using a tentative point, i.e. simultaneously pressing the right and left mouse buttons.  To actually annotate the feature, however, requires that the coordinates be manually typed in to the text editor and then placed in position.  For Easting/Northing coordinates, each of which are typically six or seven digits long, this can occasionally result  in typographical errors which are difficult to detect.

            The data point annotator is an interactive utility allowing engineer’s to easily perform Easting/Northing annotation of features in the design file.  Interface controls allow the active text angle and text height to be easily specified.  When the “Annotate Data Points” toggle is pressed an Easting/Northing annotation is made each time the data button is pressed.  Additionally, a zero-length line is placed at the exact coordinates of the mouse to allow subsequent “snapping” to the precise location of the annotation.  

            The utility also provides a vertex elevation editor.  In MicroStation no readily apparent tools are provided for changing the elevation of an individual vertex on an existing element.  The elevation of the entire element can certainly be changed but not an individual vertex.  When an element is selected, the vertex nearest to the mouse position when the element was selected will be modified.  The current elevation of the vertex is then shown on the interface form.  It may be changed to a different absolute value, or an offset difference in elevations may be applied.  The vertex is actually modified when the “Modify Vertex” toggle is pressed.
