Opacity slider on 3d models

[SCALEMODEL]

The problem that this feature will solve:

Show models in-between other models.

Brief description of the outcomes that you expect from this feature:

Possibly with opacity change it could enable you to select Sketches and 3d Model that is at 100% in opacity. Basically opacity change is a soft hide feature.

What can’t you achieve without this feature?

With opacity set lower, it will help you visualize, instead a hard toggle on and off.

Also, to quickly choose predifined material (and opacity).

Transparency toggle switch

Or like this [material popup_240708_08]

If this is to difficult to implement, a great shortcut would be a way to “Pick Face Color” (incl transparency). Is so, you could pick of present item or even build a small selection on-the-side to use.
