Ken Posted December 31, 2013 Share Posted December 31, 2013 Just about to submit a bug report, but wanted some confirmation. I cannot render Hidden Line for an extrude of a polyline containing circular segments. A 3D viewport of it on a sheet layer won't update, and when a bit more complex with many other viewports, there's a huge lag in viewport updating. Perhaps related to the other discussion: http://techboard.vectorworks.net/ubbthreads.php?ubb=showflat&Number=193724#Post193724 See attached file. What am I doing wrong? Quote Link to comment
Kevin McAllister Posted December 31, 2013 Share Posted December 31, 2013 There's definitely a bug. If you go into your VW preferences, on the 3D tab, what's your 3D conversion resolution set to? If mine is set to low/med/high it renders as expected. If its set to very high it doesn't render at all. Even with only that one object in the file. I'd be curious if you have the same results. I would file it or wait for Jim to follow up in the forums after New Years.... Kevin Quote Link to comment
Ozzie Posted December 31, 2013 Share Posted December 31, 2013 Hi Ken, I know nothing about Rendering really but had a play with it See attached Quote Link to comment
Kevin McAllister Posted December 31, 2013 Share Posted December 31, 2013 Ozzie, The file you posted back still shows the same problem on my machine. The background render completes but the hidden line doesn't unless I reduce my conversion resolution as above. What's your conversion resolution set to? I notice you're on a PC so it might be a Mac bug. An object this simple shouldn't be choking VW even when the conversions resolution is set to very high..... Kevin Quote Link to comment
Ozzie Posted December 31, 2013 Share Posted December 31, 2013 Hi Kevin, Computer specs in signature wrong ? have to change them On my Toshiba lappy at the mo It has a Nvidia GT 750M 2gb and with 3D conversion resolution set to Very High Hidden Line does not work Works in Lower resolutions Tried it on my drawing puter also ? it has Nvidia GTX 770 4gb Same Darrell Quote Link to comment
Ken Posted January 1, 2014 Author Share Posted January 1, 2014 Kevin, you?ve nailed the precise issue again ? 3D conversion resolution. When I set it back to High (from Very High), it renders okay. In fact, Update All Viewports (I have 47 viewports) now take only 35 seconds instead of over 2 minutes. Most are Hidden Line render. I went further and tried the Medium setting. While Update All Viewports is even quicker (20 seconds), there are some jagged octagon-looking shapes where I have extruded circles and circular solids. So it seems the High setting is the good balance for me. I probably had ambitiously set all my 3D prefs to their max thinking my hotrod 3.5GHz i7 iMac can handle anything. And in this document that lags, I have a good number of circular-infused polyline extrudes and curvilinear geometry. It?s a bit disappointing that geometry with many circular forms can affect a fast desktop computer. But what a relief. Thank you both for looking into it. Quote Link to comment
Kevin McAllister Posted January 1, 2014 Share Posted January 1, 2014 Glad to help. I still think you should bug submit it. That geometry isn't particularly complex so the rendering shouldn't be failing. Historically I've kept my 3D conversion resolution on Very High. There was a recent post by someone from NV (possibly Jim but more likely Dave) about setting it lower for best results. The problem I've found is that this setting is universal, so something 3" in diameter and something 30' in diameter seems to have the same number of facets. I've been working on a project that has walls with a 15' radius so the facets became very obvious in most render modes. The facets also tend to show for small objects destined for 3D printing. Its fine to suggest using a lower quality level but in practice its not that easy. Kevin Quote Link to comment
Ken Posted January 1, 2014 Author Share Posted January 1, 2014 I'll submit it as a bug. Also the objects I'm drawing are very small. I'm using thousandth of an inch (0.001 inch) as edge fillet for example. I didn't know it was also a factor. Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted January 6, 2014 Vectorworks, Inc Employee Share Posted January 6, 2014 Very High should never be your default setting, set it something more reasonable like Low or Medium. Quote Link to comment
