 Length
Overview
Prior to SketchUp 2015, Length
used to be derived from Float
. This is no longer the case.
Because length units are used so often in SketchUp, a special class has been added to make it easier to work with length values. You can use a Length object any place that you would use a Float.
Internally, all lengths in SketchUp are stored in inches. The Length class stores values in inches as well. A number of methods have been added to the Ruby Numeric class to do units conversions.
The setting for the Length Format and Length Unit can be retrieved from the Sketchup::Model#options by querying the “UnitsOptions” Sketchup::OptionsProvider for “LengthFormat” and “LengthUnit” respectively.

Instance Method Summary # collapse

#<(length2) ⇒ Boolean
The < method is used to see if one length is less than another length.

#<=(length2) ⇒ Boolean
The <= method is used to see if one length is less than or equal to another length.

#<=>(length2) ⇒ Integer
The <=> method is used to see if one length is less than equal or greater than another length.

#==(length2) ⇒ Boolean
The == method is used to see if one length is equal to another length.

#>(length2) ⇒ Boolean
The > method is used to see if one length is greater than another length.

#>=(length2) ⇒ Boolean
The >= method is used to see if one length is greater than or equal to another length.

#inspect ⇒ String
The inspect method is used to retrieve an unformatted string for the length, which is the length in inches, regardless of the user's model unit settings.

#to_f ⇒ Float
The to_f method is used to convert a length to a normal float.

#to_s ⇒ String
Format a length as a String using the current units formatting settings for the model.
Instance Method Details
↑ #<(length2) ⇒ Boolean
The < method is used to see if one length is less than another length.
For example, if l1 = 1.0.inch and l2 = 1.000001.inch then l1 == l2 so l1 < l2 should return false.
↑ #<=(length2) ⇒ Boolean
The <= method is used to see if one length is less than or equal to another length.
↑ #<=>(length2) ⇒ Integer
The <=> method is used to see if one length is less than equal or greater than another length. Because we change == for Length to do a test based on a tolerance, we also need to change <=> to also take tolerance into account.
↑ #==(length2) ⇒ Boolean
The == method is used to see if one length is equal to another length.
The equality comparison on Length values uses the default tolerance that SketchUp uses for comparing lengths.
↑ #>(length2) ⇒ Boolean
The > method is used to see if one length is greater than another length.
For example, if l1 = 1.0.inch and l2 = 1.000001.inch then l1 == l2 so l1 > l2 should return false.
↑ #>=(length2) ⇒ Boolean
The >= method is used to see if one length is greater than or equal to another length.
For example, if l1 = 1.0.inch and l2 = 1.000001.inch then l1 == l2 so l1 >= l2 should return true. Also L1 <= l2 would return true.
↑ #inspect ⇒ String
The inspect method is used to retrieve an unformatted string for the length, which is the length in inches, regardless of the user's model unit settings. See Length.to_s for a way automatically format your Length to the user's model units.
↑ #to_f ⇒ Float
The to_f method is used to convert a length to a normal float.
