Defined in:

Overview

Until SketchUp 2018 ‘Geom::Transformation.scaling(scale)` modified the 16th value in the transformation matrix. This way of scaling the matrix isn’t fully accounted in all places in SketchUp. There are also a number of exporters and render engines which also doesn’t fully handle this.

Examples:

Workaround for SketchUp versions older than SketchUp 2018

tr = Geom::Transformation.scaling(scale, scale, scale)
