Viewing from below horizon

[Al]

(from a user email)
I'm interested in the RPS 3D PDF program, for displaying files I create in Sketchup5 or GoogleSketchup Beta. The chief feature I need is something that lets the user orbit the image.

Your sample 3D PDF provides a tool bar that offers a Pan mode and Zoom mode.
Yet both those tools are provided by the Acrobat Reader already, I assume from its own toolbar. Also on your sample 3D PDF toolbar I see an icon for Rotate. It's been unresponsive, for the most part; once, when it was active, I found that it could do orthogonal rotations around a single axis. But that doesn't facilitate a true orbit, of course.

Suggestions?

We use the same tools as Adobe Reader (in interactive 3D mode)

You can orbit the image entirely. However, it you had checked 'Above model base only', then you cannot spin below the model.

We just added this feature last week, and we may have made it the default (by mistake).
(We created it for a user who wanted to spin around models which were placed on a Google Earth ground plane, and did not want the users to be able to go below the ground.)

Turn this off and you will be able to spin all around the model. We will make unchecked the default.

Try turning off this Camera Position setting and see if you get a better result.

I am made a 3D pdf by the RPS 3D PDF. I can't rotate the model upside down. Is there anything have to set in RPS 3D PDF or in Sketchup?

On the "Options/Model" dialog, there's a checkbox for constraining the rotation to "above the base".

I assume this is checked for you, since the I see that Bottom view doesn't appear in the standard view list:

Try un-checking that box, remake the PDF, and see if you then can rotate below the model.
