Shapes Disappearing with OR

[Don6218]

No, no. Go up by 30 or so, to something like 90. You can try 30 and see if it gets worse, though. If it does then we know what the problem is

Oh, ok. Sorry, just numbers on a screen, hehe! They can be changed, thank you again. Sorry to be such a bother.

YES! That worked just as you said. Thank you for pointing me in the right direction. I can see the walkways now from the cab as it should be. Should I compress the files? or leave them as they are?

I always compress shape files, but that's just my thing. It should work just as well either way, but will likely require a bit more memory uncompressed (compressing reduces file size by something like 15 times)

I've always left shapes uncompressed. My unscientific reasoning is that uncompressing at runtime takes up CPU and that's more precious than memory for most people.

I've often wondered about that, would be interesting to know if the development team had any data on that. I'd have to think that the nanoseconds ( would that be the range? ) saved uncompressing a file would add up.

I think about it too. These days... with fancy CPU's and Graphics cards that didn't exist in 2001 and systems with much more ram... compressing should hardly make a difference at all. Willing to be wrong... but I'm speaking based on what limited information I have.
