Hello all, I am having trouble with 3D pdf files rotating oddly and wondered if anyone can shed any light on the problem. It seems when I include 3D content in my pdf files, the centre of rotation is miles away from the structure and as soon as I begin to rotate it the image appears blank. From what I have read, the centre of rotation should be in the middle of the clipping planes. Correct me if I am not understanding this correctly, but my model is a saved view with a clip volume and no camera on, so I was expecting it to rotate about the centre of the clip volume but this is not happening. Any suggestions gratefully received. I have attached a sample of the problem.
Clip Volume is not the same as View Attributes Clip back and Clip front.
And first you have to set View Depth from icon in View Attributes.
But sometimes it seems to me that the 3dpdf 'learns' what id should rotate about. Make a rotation so it off screen, then use the move tool to get it back, try rotate again. Iterate a few times.

My observations are: the rotation centre is the centre of the 3D-Data's Cube you have within your 3D-Modell your printing.
So I often create a saved view, create a new 3D-Model and attach this with that saved view and do the 3D-Pdf printing.

Frank is correct - do a fit all and you'll see your models extents - in that View Window!
Long time ago Ray explained all this in different posts.
If you use a camera the pdf-printer uses the cameras settings.
