Query Construction XLines
 
 
 

Once created, you can query the first point of a constuction xline using the BasePoint property. The second point used to create the xline is not stored with the object. Instead, use the DirectionVector property to obtain the directional vector for the xline.

Query a construction line

This example finds the base point and directional vector for the xline created in Add a construction line

Dim BPoint As Variant

Dim Vector As Variant




BPoint = xlineObj.basePoint




Vector = xlineObj.DirectionVector
