transparent surface bodies

[batstar]

Good morning to all,
I have a combination with third-party components that are seen by inventor as surface bodies, in the iam you see everything as it must be with the right appearance, when I put it on the table those surface bodies appear to me as transparent, but in transparency only the front surfaces, for example a cube seen of 3/4 I see the three transparent faces in front with the only contour and the three opaque behind. I tried the various options and changed aspects but nothing... .
Thank you.

Hi.
with the 2018 version there is the tab dedicated to the creation or modification of the view (see photo)
in previous versions, if I don't remember badly, you need from the side browser of table 2d, select the view and with the right button, activate the views of the surfaces
