[Code] entities.add_linear_dimension

[TIG]

Code:

entities-add_linear_dimension.rb

Adds new Method the Sketchup Entities class

add_linear_dimension(start_point, end_point, offset, rotation)

The first pair are Sketchup::Point3d's (or as Arrays [x,y,z]).
The second pair are both optional:
. 'offset' determines the offset from the two points.
default=0.0, as number [==inches] or units [e.g. 50.mm or 2.inches] or a string
that could be read as a length [e.g. "50mm" or "2""].
Note that there are NO leaders drawn for an offset dimension.
. 'rotation' turns the dimension about the length-axis (of 2 points).
default=0.0, it is entered in degrees.
These two work together:
an offset of 0 and a rotation of 0 give a 'flat' dimension spanning
between the two points,
an offset of 0 and a rotation of 90 give a 'vertically' oriented
dimension spanning between the two points,
an offset of 2" with a rotation of 0 gives a 'flat' dimension offset
from the two points,
an offset of 2" and a rotation of 90 gives a 'vertically' oriented
dimension offset 2" above the two points.;
and so on...

Essential:
Needs 'linear_dimension.skp' in the Plugins folder
it could be customized: keep it 1" long x 0" high.

Tip:
If you want a dimension that is readable from any direction then add
two on top of each other, one rotated at 0 and the other at 90. As one
disappears from view the other will become visible...
