Descriptive geometry true length of a line

What do you mean by true length of straight line?
A true length line is the actual straight-line distance between two points.
In orthographic projection, a true-length line must be parallel to a projection plane.

What is a line of true length?
In geometry, true length is any distance between points that is not foreshortened by the view type.
In a three-dimensional Euclidean space, lines with true length are parallel to the projection plane..
What is the true length in descriptive geometry?
The true length (TL) of a segment is the distance between its end-points.
Finding the true length of a segment is a basic problem in descriptive geometry..
What is true length in projection of line?

TRUE LENGTH (T.L.) AND TRUE INCLINATION (T.I.)
The length of T.V. is dependent on θ.
T.V. and θ are inversely proportional.
The position of T.V. is a function of the True Inclination with the V.P., i.e., Φ.
If the F.V. of the line is T.L., then it must appear at an angle of θ with the xy line.

When a line segment in space is oriented so that it is parallel to a given projection plane, it is seen in its true length in the projection on to that projection plane.

A true length line is the actual straight-line distance between two points. In orthographic projection, a true-length line must be parallel to a projection plane. A line can also appear as a point, called an end or point view. This occurs when the line of sight is parallel to the true-length line.

To find the true length of a line you must take a view parallel to the line; in other words, if a line is a parallel to the folding line in one view, it is shown in true length in the adjacent view.

How are perpendicular measurements used in descriptive geometry?

As locations, and therefore measurements, are involved in descriptive geometry we devise a method by means of which accurate perpendicular measurements are represented on a sheet of paper

Finding the true length is a fundamental process in descriptive geometry that advances the problem-solving to the next steps to reach the solution. To find the true length of a line you must take a view parallel to the line; in other words, if a line is a parallel to the folding line in one view, it is shown in true length in the adjacent view.The true length (TL) of a segment is the distance between its end-points. Finding the true length of a segment is a basic problem in descriptive geometry. The constructions that can be used to solve this problem are based—among other things—on the property that a parallel projection between two coplanar lines preserves distances.In geometry, true length is any distance between points that is not foreshortened by the view type. In a three-dimensional Euclidean space, lines with true length are parallel to the projection plane.
