Purpose
To convert 2D Polylines normally representing contours to 3D Polylines. The main benefit after conversion is to enable 2D Polylines with arc elements to have their arcs* recognised when creating a ground model or when making a section using some menu items in Sections, Create Sections from Drawing entities. *The arcs are divided into line elements within the 3D Polylines at a resolution expressed as an angle (default of 5deg.) and set by entering at the Keyboard "KTFARC".
Operation
Return to not keep the original entities. Select one or more 2D Polylines.
