I want to automatically create TopView scenes for the selected components.
If I were to do it manually I would:
Set Camera Parralel Projection >> Open object instance >> Select Top in Views toolbar >> Zoom Extents >> Add Scene.
I have implemented this logic in a Ruby script.
But the result is not the same as performing the operations manually in SketchUp.
The camera location created with the Ruby script is not what I expected.
mod = Sketchup.active_model
selected_objects = mod.selection.to_a
# Parralel Projection
mod.active_view.camera.perspective = false
# Open the instance
instance_path = Sketchup::InstancePath.new([object])
mod.active_path = instance_path
# Set Top view
# Zoom Extents
# Add new page in model
mod.pages.add(object.name + "_TOP")
# Close the instance
mod.active_path = nil
How can I set the Top View in the local object environment?
I’m probably overlooking something…
Sketchup.send_action is not synchronous. The successive Ruby statements can be executed before the view is done changing.
To speed things up, temporarily switch off scene transitions.
Secondly I don’t think I’d do it the way you’ve done it (ie, using the
Before the iteration, I would setup a camera looking straight down and set it to the view:
center = model.bounds.center
cam = Sketchup::Camera.new(
center.offset([0,0,model.bounds.depth]), center, Y_AXIS, false
During the iteration I would
zoom(object) instead of entering in the object’s edit context.
Thanks @DanRathbun for your comment
In the overall script I already turned off the scene transitions so that it improves the speed.
I didn’t realize / read that Sketchup.send_a is not synchronous
That caused the main problem.
It was indeed successful by setting the camera properly.
tr = mod.axes.transformation
view = mod.active_view
center = mod.bounds.center
new_cam = Sketchup::Camera.new(
center.offset([0,0,mod.bounds.depth]), center, object.transformation.yaxis.transform(tr), false
view.camera = new_cam
