Not Selecting / Disappearing Annotations

I recently upgraded to Rhino 6 at work. The first project I’m working on was importing a somewhat large CAD file of a site plan.

For some reason I noticed a lot of the small annotations and dimensions disappear when zoomed out, and because of this I cannot select them. I never had this issue in Rhino 5.

Also related is when I zoom region or zoom window into a specific area, then pan somewhere else, my annotations also disappear until I perform a zoom region on that area. Again I never experienced this in Rhino 5.

Hi Jonathan - can you run the SystemInfo command in Rhino and paste the results here?

Hi Jonathan- a couple of things - one is your video card driver is a couple of years old - whether or not that comes into play in this problem, it is probably a good idea to get the latest, from the NVidia website - (don’t rely on the Windows check for the latest).

The other thing is I was reminded by the developer that V6 has a ‘degrading’ of annotation below a certain size to lines and then it goes away - so, is there a stage in your operations where the disappearing annotations become lines before they disappear?


Hi Pascal,

Thanks for the advice regarding the video driver. I will try to manually update from the website and see if that makes a difference.

Also, yes the annotations turn to lines at a certain distance. Actually I am fine with this graphically, but the main problem was not being to select them at all if they degrade all the way to disappearing. Is there a way to disable this effect?


Hi Jon - looking at this here, Dimensions do not disappear as a whole, but the dimension text showing the value disappears - are we seeing the same behavior? For text blocks, I think the problem may be, that an entire block of text will disappear if the individual test elements get below a certain size, even if the overall block of text should be visible, maybe as a solid rectangle or something, am I on the right track?


Hi Pascal, I was going to make a screencapture but now I can’t seem to get it to behave the same way… maybe it was just a fluke from running too many things at once or something… It was not a whole block of text disappearing, but rather individual texts in a close region. Also I was operating in Top View as well when this was still happening, so it wasn’t a perspective issue. Hoping it was just a random issue. I’ll post a follow up if I can get it to behave like that again.


Hi Jon - ok - if you see it again and can come up with steps to reproduce, that would be ideal, but I know about these hard to reproduce deals, they can be frustrating.
