Find points were used to create an UCS

[ngocson8335]

Hello everyone,

I created a UCS by 3 edge points in a part. Now I would like to specify back which edge points that I used to create that UCS.

Thank you.

You have to look at the UCS Definition.  There is a method: GetByThreePoints :

Dim PickThis As UserCoordinateSystem = ThisApplication.CommandManager.Pick(SelectionFilterEnum.kUserCoordinateSystemFilter, "Select UCS")
If IsNothing(PickThis) Then Exit Sub ' If nothing gets selected then we're done
	
Dim Origin, xPoint, yPoint As Object

PickThis.Definition.GetByThreePoints(Origin, xPoint, yPoint)
Logger.Trace(CType(Origin.Type, ObjectTypeEnum).ToString)
Logger.Trace(CType(xPoint.Type, ObjectTypeEnum).ToString)
Logger.Trace(CType(yPoint.Type, ObjectTypeEnum).ToString)

Although, when I picked edge midpoints the Object returned in the edge it self, but Endpoints actually return as vertex objects.
