superden01 Posted October 2, 2006 Share Posted October 2, 2006 Hi there, I have recently updated from vw11.5 to vw12.5 and have been working through the changes and fixing any little issues that I can. I however am just trying to fix a little issue when zooming with the mouse scroll wheel. When you zoom in the image becomes very blocky and will pause, briefly before the image corrects itself. I have done a search and found a few threads which mention this problem but I have not been able to find one that resolves the issue. Does anyone know if there is a solution for this problem. Any help would be much appreciated Denny Quote Link to comment
Travis Posted October 2, 2006 Share Posted October 2, 2006 You probably have Quartz Imaging turned on in your VW preferences. This yeilds a very nice image, but at the expense of the "self-correcting" process you describe. Turn off the option (which I normally do) and you'll have the same thing as 11.5 Good luck, Quote Link to comment
superden01 Posted October 2, 2006 Author Share Posted October 2, 2006 Hmmm no. I thought you had it for a minute but couldnt find the Quartz image option. With further investigation I found that Quartz imaging is mac only. I am on PC. Any other ideas? Denny Quote Link to comment
Guest Posted October 2, 2006 Share Posted October 2, 2006 This is the expected behavior on detailed and complex drawings, or slower video cards. When zooming, the screen needs to redraw every movement. To speed things up, the drawing within the application window is temporarily converted to a bitmap. When the zooming completes, the image is redrawn. The bitmap conversion step eliminates unnecessary redraws, which aid in the speed of zooming. Depending on the drawing - how many objects, type of objects, number of vertices, and alot more criteria - will determine how quick the final redraw occurs. The video card also plays a role here - the faster/better the video card, the more noticable the redraw speeds in the majority of cases. The other factor is video drivers. Make sure your video card has up to date drivers installed. This will significantly affect speed amongst other details. Quote Link to comment
Hugo Posted October 3, 2006 Share Posted October 3, 2006 Katie, I am very interested in this issue. What do you consider a slow video card? What about the Intel GMA 950 built in on a MacBook, and the PCI Express Ati Radeon X1600 on an iMac? How do these card qualify? Thank you! Quote Link to comment
superden01 Posted October 3, 2006 Author Share Posted October 3, 2006 Good point Hugo. I too would like to find this out. I am currently running an Nvidia 6600 with 256 ram and looking at data I found on tomshardware.com, relating to frames per second, My 6600 is slightly slower than your x1600, but not much. Both cards are definitely closer to the bottom than the top, but how high do you need to go. Sure bigger is better but the higher you get the more disproportional the price/performance ratio gets. I also would not like to spend to little and be disappointed. I have also had suggestions that a card with greater ram may be better, though from what I have read this my not be as important as other speed related features of the card. Any outside knowledge would be great Denny Quote Link to comment
seanSF&A Posted October 3, 2006 Share Posted October 3, 2006 Katie, Im sorry but this is just not acceptable. This did not happen in 12.0.1 so why is it happening now? My system should be more than up to the re-draws and as it managed it in 12.0.1 it must be the software that is at fault, not my video card (running the latest Nvidia driver) What has changed in the software to cause this? In which future upgrade will it be ironed out? Regards Quote Link to comment
seanSF&A Posted October 3, 2006 Share Posted October 3, 2006 On reviewing other threads that mention this problem, it all becomes clear. All the posters that are reporting 12.5 to be slower are running PC's and all the posters reporting beter performance are running it on macs. So why is this please? Quote Link to comment
Guest Posted October 3, 2006 Share Posted October 3, 2006 OKay - I didn't realize that this post was exclusive to 12.5. If you are on a PC - check to make sure the video driver is up to date. Quote Link to comment
superden01 Posted October 3, 2006 Author Share Posted October 3, 2006 Yes latest driver downloaded from Nvidia.com on Monday. version 91.47. Still no fix Quote Link to comment
Guest Posted October 3, 2006 Share Posted October 3, 2006 I have the same driver version installed here. If you want, send a sample file demonstrating this and I will see what my test results end up as. Quote Link to comment
superden01 Posted October 3, 2006 Author Share Posted October 3, 2006 I dont think it is related to a particular file. We have 4 pc's running 12.5 here and all working on various files both new and old. All with same problem. Quote Link to comment
Guest Posted October 3, 2006 Share Posted October 3, 2006 I understand where you are coming from. With that said, I don't see a difference and I have a video card that's on the low end of the spectrum. If I can take a look at the files that you are seeing and try them on my computer, it can either rule out a number of factors, or provide additional information into the situation. It's up to you. However, without a file, I can't duplicate the problem and therefore have no other suggestions. Quote Link to comment
seanSF&A Posted October 4, 2006 Share Posted October 4, 2006 how do I send a file? Quote Link to comment
MikeN Posted October 4, 2006 Share Posted October 4, 2006 (edited) I too have been experiencing similar problems. I posted this on the ListServe on Sept. 21.... Since upgrading to 12.5 I?ve been experiencing the following video display issues: - When zooming in and then zooming out, everything outside the viewable area disappears. (Manual regen fixes this issue) - When zooming in and out Vector Caching seems to freeze leaving me with a low-res and un-editable drawing file. This happens whether Vector Caching is on and off. (Manual regen fixes this issue) - When zooming in and out, the selection handles of a selected object disappear. (Manual regen fixes this issue) My current configuration: - VWA 12.5 with Renderworks - WinXP Pro with SP2 - Intel Pentium D 3.2ghz - 2GB Ram - nVidia GeForce 7800 GTX 256mb using Digital output. (1680x1050) None of this happened in 12.0.1. and installing the latest graphics drivers did not solve the problem. I?m getting tired of manually regen-ing, so any insight would be greatly appreciated. Edited October 4, 2006 by Runtime Error Quote Link to comment
MikeN Posted October 4, 2006 Share Posted October 4, 2006 Bit of an update on these matters over here. Quote Link to comment
Amy L Posted October 7, 2006 Share Posted October 7, 2006 For what it's worth, this is one of the first things I noticed about the12.5 upgraded floor plans (created in 12.0) while zooming. Mostly everything was as it should be, but occasionally, while zooming in and out, things get pixelated. (This is with quartz imaging selected.) It corrects itself quickly, but is definitely different from 12.0. I'm also test driving on a laptop that is not my work-horse, which could explain the difference. 12.5 test run on: Mac PowerBook Laptop 1.67 Ghz PowerPC G4 2GB DDR2 SDRAM version 10.4.8 Quote Link to comment
seaprt Posted December 12, 2006 Share Posted December 12, 2006 I don't think this is a pc or mac issue. This is a perception issue. Most pc users are probably coming from AutoCad which has a real time scroll zoom without any annoying pausing bitmaps. We can try all kinds of settings and upgrade to the fastest equipment, but it is still not going to fix the scroll zooming issue. My suggestion would be for Nemetschek tech people to actually try the AutoCad scroll zoom to realize what posters are referring to. Maybe then, Nemetschek can realize and fix the problem. By looking at the posts, this is a very persistent and real problem. I hope this gets fixed soon in a patch or next version of Vectorworks. Thanks, seaprt Quote Link to comment
ErichR Posted December 14, 2006 Share Posted December 14, 2006 It's not a zoom issue necessarily. Lots of 3D apps allow smooth, 'rendered', real-time image manipulation. VectorWorks doesn't: GL sort of, RenderWorks not. A software; not a video driver issue. Quote Link to comment
COMJAX Posted September 6, 2007 Share Posted September 6, 2007 manually regen-ing, I give up. How do you do a manual regen? Quote Link to comment
Guest Posted September 6, 2007 Share Posted September 6, 2007 Double click on the Pan tool (looks like a hand in the Basic tool palette) Quote Link to comment
Hugo Posted September 7, 2007 Share Posted September 7, 2007 What about the zoom in VW2008? Is it faster? Quote Link to comment
