However, it is possible to make to a 'Point' object appear larger or smaller on the screen.
Just got to...
Preferences -> Visualization -> View/Screen
...and select the 'Calibrate' button in the middle of the dialog and when the next dialog comes up, just move the sliders so that you have as large, or small, a number as possible for both the Horizontal and Vertical scales (If there is an option to 'Lock Resize Sliders' make sure that it's toggled on. If you don't have that option, then you'll need to make sure that the values on slider are the same).
Now this will also make ALL on screen, non-geometric objects, including the Point, appear larger or smaller. This includes the reference CSYS in the lower Left-corner of the screen, any coneheads, the WCS, line end splats (*), etc.
Yes! Its solved! Thank you for your answer. That is useful information for us.
We are migrating the CATIA V5 to NX now. We could be select the point style and we used "." with CATIA, so I asked you this question. That's my background.
Thanks and regards,
