Zoom

[Andy]

Hello,

When I use pgup,pgdn for zoom somedays it is slow and jerky and other days fast and smooth. I try to test this with small drawings, same results. No other programs running etc. Any ideas?

Thanks,

Andy

May be related to the Enable OpenGL® drawing option under Screen/Configure/Screen. Test things out with the option on, and off, and report back. We tend to set this off as a default.

Dave,

My "Enable Open GL Drawing" is checked but it's greyed out. (V8 Beta 3). Any ideas?

It'll grey out when you've got shading on. Can't shade without it!

Dave,

I tried the open GL Switch and no improvement.

Here are a couple graphics-speed related questions: ) Do you often use different line styles? These are historically slower, most notably with OpenGL drawing ON, than solid lines. 2)Do you use "TrueColor" graphics? This, too, is historically slower than "HighColor", or 65K colors. 3) Do you sometimes view parts at drastically different screen scales than that at which the geometry was first drawn? Screen/Next/Regen could help there. 4) Do you have lots of note and dimension text? When these get small and are drawn as rectangles, it's considerably faster than drawing the full text everytime. And even then, TrueType fonts tend to be a little slower than our fonts.

Hope this helps...

Hello,

The only thing I have in the drawing is a simple square for testing only. No text, no special line styles, etc. I dont know where to set true color or high color (Tell me about that please) and therefore I am using the same everything and still get an upredictable fast or slow zoom???

Just checked, High color 16bit
