Locked in Perspective View

SketchUp
1

I am working on a file and the view is locking in perspective view. I clicked a button and it wont switch to two point perspective. When I click two point perspective it switches. Then as soon as I hit the orbit button it switches back to perspective. Is there a way to switch it back to two point perspective. I have had this happen in the past and I just rode it out. Just want to know how to disable the perspective lock default so that when it happens again in the future I can fix it. Dont want to paste in place into new file and resave.

You can’t lock into 2-Point Perspective. Activating Orbit will drop out to normal Perspective. That’s normal behavior. The only way to prevent losing 2-Point perspective is to leave Orbit alone. I would create a scene immediately after selecting 2-Point Perspective so you can easily return to it.

Is there a way to accidentally lock the perspective as parallel projection? That is what happened. I would orbit then it would go to perspective but it would keep the parallel projection. Even when i would click two point perspective. It would snap back to perspective with parallel projection.

You can’t have Perspective and Parallel Projection at the same time. If you set the field of view very narrow in Perspective it would look like Parallel Projection but it still wouldn’t be Parallel Projection.

2-Point Perspective sets the camera so the “image plane” is vertical. No up or down component to the view. This means there’s no vanishing point above or below the model, only the vansihing points on the horizon. With Parallel Projection there are no vansihing points at all.

You can pan the camera and keep 2-Point Perspective but you can’t orbit.

That is exactly what happened. I screwed up the field of view. Thank you. Changed it back to the default 35. Good to go.

I don’t understand what you are talking about.
SketchUp switches between Perspective and Parallel projection methods only when you select one or the other from the Camera menu. 2-point perspective is a drawing convention that is not a “real” perspective as vertical edges do not converge to a vanishing point or the vanishing point is infinitely distant.

It might be a good idea to set up a few shortcut keys for ‘Parallel Projection’, ‘Perspective’ and ‘Two-Point Perspective’.

  • Using the \ key I can toggle between parallel and perspective (the current latest ‘Field of View’)
  • Using [Shift] plus \ I can instantly get ‘Two-Point Perspective’ from either being in parallel or perspective mode.
  • also (default) [z] gives me zoom. Then [Shift] plus sliding the magnifying glass cursor up or down changes the ´Field of View’ in degrees (or the 'Focal Length in mm). Even overrided by input.
