Imports Graphics from the current dgn and creates
linear and point features.
Since graphics are just plain lines and cells
when we attempt to create a survey from graphics, We assign features based on
the best match of certain parameters.
- Cell Name of the
Graphic Element
- Level Name
- Color
- Line Style
- Line Weight
We compare these parameters with the current
workspace feature definitions and assign the best match, If many features do
share these parameters, we will pick the first one.
It tries to match the graphic element's symbology
to the feature definition of survey elements/templates.
The steps below explain how graphic elements
work.
- First, it will
check and compare the Level Name of the Graphic Element for lines, and the cell
name for points, if it matches a Level Name or cell name of a Feature
Definition from the currently selected workspace, then that respective Feature
definition will be assigned to that element. To find this match it works its
way back from the Element Template (level name/cell name, color, line style,
line weight)>feature symbology > Feature Definition and matches.
- If the Level
Name/Cell Name cannot be found or does not exist, then next it will match all 3
attributes of the graphic element: color, line style, and line weight, if all 3
matches the element template of a Feature definition found in the workspace,
then that Feature Definition will be assigned to that element.
- If only 2
attributes are found then it will match Color and Line Style, Line Style and
weight, and Line Style only (color and weight only will not be matched and will
be assigned the default miscellaneous feature).
If many feature definitions from the workspace
share the same matched parameters, then we will use the first feature found.
