This part of the conversion and transformation series discusses a case where a hole exists in the part model and its center point in the drawing views need to be found in terms of the sheet or document units.<\/P><\/p>\n
The case is illustrated in this image:<\/P><\/p>\n

<\/span><\/P><\/p>\nThe hole is created in the ordered mode and has a profile which can be accessed as below:<\/P><\/p>\n
Dim seApp As SolidEdgeFramework.Application =
\nSystem.Runtime.InteropServices.Marshal.GetActiveObject(“Solidedge.Application”)<\/p>\nDim sePartDoc As SolidEdgePart.PartDocument = seApp.ActiveDocument
\nDim seHole As SolidEdgePart.Hole = sePartDoc.Models.Item(1).Holes.Item(1)
\nDim seHoleProfile As SolidEdgePart.Profile = seHole.Profile<\/PRE><\/p>\nThe center point of the profile is a 2d point since a profile is essentially in a 2d plane:<\/P><\/p>\n
Dim xHole As Double, yHole As Double
\nseHoleProfile.Holes2d.Item(1).GetCenterPoint(xHole, yHole)
\n<\/PRE>
\nThe center point needs to be converted to a 3d point since the hole is in 3D space on the model.<\/P>
\nHere comes our first conversion:<\/P><\/p>\n
Dim xHole3D As Double, yHole3D As Double, zHole3D As Double
\nseHoleProfile.Convert2DCoordinate(xHole, yHole, xHole3D, yHole3D, zHole3D)
\n<\/PRE>
\nThis gives the hole\u2019s center point in 3D space as illustrated in the image above.<\/P><\/p>\n
The target is to locate the same point on a sheet where the drawing views of the model are placed as shown below:<\/P><\/p>\n
![\"CAT081.png\"](\"http:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/8\/2019\/09\/CAT081-1.png\" "\\"CAT081.png\\"")
<\/span><\/P><\/p>\nThis calls for the second conversion from model to view and happens in the Draft document:<\/P><\/p>\n
Dim seDraftDoc As SolidEdgeDraft.DraftDocument = seApp.ActiveDocument
\nDim seSheet As SolidEdgeDraft.Sheet = seDraftDoc.ActiveSheet<\/p>\nDim seView As DrawingView = seSheet.DrawingViews.Item(1)
\nDim xView As Double, yView As Double, xSheet As Double, ySheet As Double
\nseView.ModelToView(xHole3D, yHole3D, zHole3D, xView, yView)<\/PRE>
\nThis converts the 3d coordinate to the 2d equivalent in the draft\u2019s view but not yet on the sheet in terms of the draft document\u2019s units.<\/P><\/p>\n
This is done in the 3rd conversion where the view coordinates are converted to sheet coordinates as explained in the previous episode of this series.<\/P><\/p>\n
seView.ViewToSheet(xView, yView, xSheet, ySheet)<\/PRE><\/p>\n
This completes the conversion of a hole\u2019s center point from the 3D model to the 2D sheet.<\/P><\/p>\n
The next part will show how to perform matrix manipulations on occurrences to move and rotate them in the assembly environment.<\/P><\/p>\n
