Lines that define the parameters of a dimension.Dimension lines are thin lines terminating in arrowheads. Place dimension lines no closer than 3/8" from the object outline. Parallel dimension lines should be a minimum of 1/4" apart. You may place parallel dimension lines more than 1/4" apart so long as the spacing between dimension lines is uniform throughout the drawing. Dimension lines are generally broken in the center of the line to provide a space for the dimension figure. Dimension figures for parallel dimension lines are staggered. In some structural or architectural drawings, you may find dimension figures placed above the dimension line.
In CAD"A witness line is part of a dimension. It's the line that extends from the outside edges of the object being dimensioned, to where the dimension text is printed. It helps to point out what points on the object the dimension is measured from."Definition of witness, relating to witness lines"b. One who furnishes evidence."
A line on a drawing pointing to another line or part to which the dimensions relate.----

A line has one dimension- length. This is evident if we compare a line to a point and a plane figure. A point has no dimension; it merely marks a location. A plane figure, such as a square, circle, or triangle, has two dimensions. They have both length and height. A line is between a point and a plane figure. It has length, but it does not have width. ------------------------ 1 dimension. Here is a comparison of dimensions: 0 (dimension): Point 1: Lines 2: Plane 3: Solid, space 4+: Hypersurfaces, hypercubes, Klein bottles

You are putting too many dimensions on it. For example, if there is a L shaped sketch and you dimension from the bottom of the L to just above the horizontal part, and then you dimension the vertical part from the end point of the last dimension you'd be okay. But, if you dimensioned both of those lengths and then the total length you would be over dimensioning the sketch.
Center lines, hidden lines, cutting plane, break lines, dimension lines, section lines, extension lines
The 4 component of linear dimensions are: 1. Dimension Lines 2. Extension Lines 3. Arrowheads 4. Numeric Value of dimension
Thin lines for outlining Thick lines for dimension Thin dotted lines Thin dotted lines Thin long chains for center lines
the first 3 dimension Television was made in 1946
1 dimension would just be lines in 1 dimension with no width or no length. You wouldn't be able to see it. Pictures on paper are in 2 dimensions. Models in space are in 3 dimensions.
For putting to many dimension on top of the dimension!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

If lines neither intersect nor are parallel, then they must be drawn in 3D space, or a higher dimension.(These lines are called skew lines)
Three, of course!
Hi The different types of Alphabet of lines are:-Visible.-cutting plane lines.-Short breaking lines.-Border lines.-Invisible lines .-Ditto or hidden lines.-Center lines.-Long break lines.-Section lines.-Dimension lines
