Chapter 6 Creating Geometry Using Ruby Scripting
Whenever you work with components in Ruby, it is very important to have the component’s
axes (the ones that you see when you edit or double-click the component) in the
correct location. Copies will be placed using a component’s origin. Double-check their
placement if your results don’t look as expected.
TIP
Figure 6.19: Selection for example
# Use this to map a component onto the center of all selected faces
mod = Sketchup.active_model # Open model
ent = mod.entities # All entities in model
sel = mod.selection # Current selection
# Get the one component’s definition
comp = nil
sel.each { |e|
if e.typename == “ComponentInstance”
comp = e.definition
end
}
# Iterate through all ungrouped faces
sel.each { |e|
if e.typename == “Face”
