Does it possible to zoom 1:1 scale a 3D model on the screen? This function is enabled on Catia V4 and V5 (which I've used in the past), sometimes useful to analyze the real dimension of the part you are working on, especially if you are drawing something very small.
I'm currently a Creo 2.0 M100 user.
No. I would be different for every monitor x resolution x window size.
I don't know if Catia takes all that in to consideration but seems unlikely in my opinion.
I hold up a ruler to my screen and zoom until I achieve close to full scale. The ability for Creo to either determine automatically or just be told the screen size and resolution to provide a full scale zoom at the push of a button would be a useful feature.
It would be useful, but I don't think it can be implemented. For instance if you were using a projector there would be no way for the software to know the throw distance and therefore how big the displayed image is. Similarly windows allows you to change the display zoom.
