[REQ]Auto Perspective

[Rich O Brien]

Is this possible?

If I have Ortho Front/Left/Right..... view in SU and I orbit it immediately change to perspective?

I do have shortcuts assigned for Perspective and Ortho but having Sketchup detect that I want to view in Ortho but swap back to Perspective on orbit would be a nice feature.

Cool idea. I could use that.

Sounds like a job for the 'toolObserver' & id nr 10508 (CameraOrbitTool).

do you have a shortcut for 'Camera' >> 'Previous', and is that the behaviour your looking for?

I can see the point but I have a shortcut for camera perspective. It toggles perspective on and off and it's very convenient to me... also for dealing with the famous clipping issues one has some times...

[Rich O Brien]

I too toggle but I am used to Blenders auto perspective mode.

Snapping out of ortho on orbit seems a logical move.

Unless you need to zoom in very close.

It's a great idea so I had a go and it seems to work under Windows.

Save this code as a .rb file and drop it into the plugins folder. I'm a Ruby newby so it might violate proper code habits but feel free to comment.

require 'sketchup.rb'

module MB
class OrbitToPerspectiveObserver < Sketchup;;ToolsObserver
	def onActiveToolChanged(tools, tool_name, tool_id)
		if tool_id==10508
			camera = Sketchup.active_model.active_view.camera
			status = camera.perspective?
			if !status
				camera.perspective = true
			end
		end
	end
end

class OrbitAppObserver < Sketchup;;AppObserver 
	def onNewModel(model)
		model.tools.add_observer(OrbitToPerspectiveObserver.new)
	end
	def onOpenModel(model)
		model.tools.add_observer(OrbitToPerspectiveObserver.new)
	end
end

Sketchup.add_observer(OrbitAppObserver.new)

end #module

edit: changed the code so it will now auto-start when Sketchup starts OR a new file is made. Note: double-clicking on a file in windows explorer will not get noticed by these observers

on the mac, orbit automatically switches to perspective and remains there, doesn't that happen on a PC?

If I am in ortho and orbit i remain in ortho

I don't see that on my Mac. When I orbit the view shows an isometric view but it is still parallel projection.

This is what I see on my Mac:

Front view.

After orbiting.

After manually switching camera to Perspective .

I select Menu >> Camera >> Parallel Projection

I Orbit

I check Menu >> Camera : Perspective is selected

are you seeing something else??

EDIT: I had left the code from above active when I started test, it causes Perspective to 'Stick'

your to quick dave I edited my question because

What did you use to do this Image Rich. It would help in a project I'm developing...
