Check "if view?"

CadFather

does anyone know if there is a way to check whether one is aligned to a standard view (current view)?

tried various combinations, "if view=='ViewTop" etc. there seems to be nothing in the api.

Thanks

This will return true if the view is looking straight down (top view)
if Sketchup.active_model.active_view.camera.zaxis == [0,0,-1]

I like Camera#direction - it's more clear than zaxis.

Vector3d#parallel? and Vector3d#samedirection? might be better than == since they consider tolerance.

thanks J, that's promising!

EDIT: something's moving...! will report back

yes....just wonderful, all works great.

Jim, are you trying to scare me?

Thanks!

Not very scary.


cam_dir = Sketchup.active_model.active_view.camera.direction
if cam_dir.samedirection?(Y_AXIS)
  # Front
elsif cam_dir.samedirection?(Y_AXIS.reverse)
  # Back
elsif cam_dir.samedirection?(X_AXIS)
  # Left
elsif cam_dir.samedirection?(X_AXIS.reverse)
  # Right
elsif cam_dir.samedirection?(Z_AXIS)
  # Bottom
elsif cam_dir.samedirection?(Z_AXIS.reverse)
  # Top
else
  # Not aligned to Std View
end

Jim, that neat way, makes perfect sense..!

here's the follow up to the previous if anyone has any idea:

working with this below, all good. but are there not controls for the 'look around' tool as well?
(nothing in the api)

   def onKeyDown(key, repeat, flags, view)
		case key
		 when @upArrow  then  Sketchup.active_model.active_view.zoom 1.01
		 when @downArrow  then  Sketchup.active_model.active_view.zoom 0.99
		end

what i'm trying to achieve is a plugin that will use the keyboard to incrementally spin and turn around the model or a selection. (will be out in 2019).

Indeed much nicer way to do it, jim
