Hello, With the method below, I am able to find the tilt angle in X of a component relative to the SketchUp scene. mod = Sketchup.active_model sel = mod.selection sel.grep(Sketchup::ComponentInstance).each do |s| xaxis = s.transformation.xaxis angle_between = xaxis.angle_between(X_AXIS) a…

But if the instance is at the top model entities context, then you can use the world X_AXIS as a reference. angle_in_plane( sel[0].transformation.xaxis, X_AXIS ).radians.round

Perhaps like this ?: [image] Ruby angle_between issue Ruby API More elegant solution: # Counter-clockwise angle from vector2 to vector1, as seen from normal. def angle_in_plane(vector1, vector2, normal = Z_AXIS) Math.atan2((vector2 * vector1) % normal, vector1 % vector…

Thanks for your dezmo example, It doesn’t seem to work with components. I tried to readjust the formula for a selected component and the result is always -90 °. mod = Sketchup.active_model sel = mod.selection sel.grep(Sketchup::ComponentInstance).each do |s| tr = s.transformation xaxis = t…

[image] juliendufren2016: I am not sure which are vector1 and vector2 in the example eneroth3? Julia’s example has a method description: Counter-clockwise angle from vector2 to vector1, as seen from normal. So therefore, vector1 is the vector that is being tested, and vector2 is the refer…

I can also write it like this: mod = Sketchup.active_model sel = mod.selection sel.grep(Sketchup::ComponentInstance).each do |s| xaxis = s.transformation.xaxis angle = Math.atan2((X_AXIS * xaxis) % Z_AXIS, xaxis % X_AXIS).radians.round p angle end Or like this: Sketchup.active_model.selec…

[image] juliendufren2016: I can also write it like this: Why would you want to? It is more self-documenting to use the angle_in_plane method within your extension submodule or class. For more information, … the Enumerable#grep method takes a block. You do not really need to use Array#each .…

[image] DanRathbun: It is more self-documenting to use the angle_in_plane method within your extension submodule or class. You are right Dan! I am doing this only to better understand what is going on. In reality if the code is executed in a single block, it is easier for newbies in ruby li…

[image] juliendufren2016: X_AXIS #X axis of SketchUp Scene Please note that your comment is not exactly true in all cases. The API constants ORIGIN, X_AXIS, Y_AXIS, and Z_AXIS are the preset world (model) axes of the IDENTITY transformation. These should never change (ie, they are constants.…
