# Element Tapemeasure

JXG.GeometryElement
↳ JXG.Line
↳ Segment
↳ Tapemeasure

A tape measure can be used to measure distances between points.

The two defining points of the tape measure (which is a segment) do not inherit by default the attribute "visible" from the segment. Otherwise the tape meassure would be inaccessible if the two points coincide and the segment is hidden.
Defined in: measure.js.
Extends Segment.

Element Detail
Tapemeasure

This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "tapemeasure".
Possible parent array combinations are:
  The two arrays give the initial position where the tape measure is drawn on the board.

Throws:
{Exception}
  If the element cannot be constructed with the given parent objects an exception is thrown.

Examples:

    // Create a tape measure
    var p1 = board.create('point', [0,0]);
    var p2 = board.create('point', [1,1]);
    var p3 = board.create('point', [3,1]);
    var tape = board.create('tapemeasure', [[1, 2], [4, 2]], {name:'dist'});
