When you access 2D objects from a Solid Edge Drawing, they are lying on a drawing sheet which belongs to one of these categories:
- Working Sheets.
- Background Sheets.
- 2D Model Sheet.
- Drawing View Sheet.
The working and background sheets are part of their respective “sections”.
So the declaration for these look like:
Dim seApp As SolidEdgeFramework.Application = Nothing
Dim seDoc As DraftDocument = Nothing
Dim seSections As Sections = Nothing
Dim seWorkingSection As Section = Nothing
Dim seBackgroundSection As Section = Nothing
Dim seSheet As Sheet = Nothing
Dim seSheets As SectionSheets = Nothing
These sections can be accessed separately as below:
seApp = Runtime.InteropServices.Marshal.GetActiveObject(“SolidEdge.Application”)
seDoc = seApp.ActiveDocument
seSections = seDoc.Sections
WorkingSection = seSections.WorkingSection
seBackgroundSection = seSections.BackgroundSection
and the sheets in each of these sections can be accessed as below:
seSheets = seWorkingSection.Sheets
seSheets = seBackgroundSection.Sheets
Similarly, the 2D Model sheet can be directly accessed from the sections:
se2DModelSheet = seSections.Get2DModelSheet
To access the drawing objects, loop through each sheet as below
For Each seSheet In seSheets
Within each sheet object are the various drawing or graphical elements.
Note that these drawing objects are the ones placed directly on the sheet and accessible only via their collections. Also note their types few of which are listed below:
Points – Point2d via the Points2d collection
Lines – Line2d via the Lines2d collection
Arcs – Arc2d via the Arcs2d collection
Circles – Circle2d via the Circles2d collection
Drawing views are also one of these.
Dim seDrawingView As DrawingView = seSheet.DrawingViews.Item(1)
Drawing views in turn contain 2d objects which are of type with a DV prefix:
Points – DVPoint2d via the DVPoints2d collection
Lines – DVLine2d via the DVLines2d collection
Arcs – DVArc2d via the DVArcs2d collection
Circles – DVCircle2d via the DVCircles2d collection
There’s a twist to this story however.
You can right-click on a drawing view and select ‘Draw in View’
The 2d objects added in this mode can be accessed through a special sheet belonging to the drawing view:
Dim seViewSheet As Sheet = seDrawingView.Sheet
This sheet is internal to the drawing view with a random number as its name. Note that the 2d objects on this sheet are of type Line2d accessible through the Lines2d collection for example and are not DVLine2d objects.
