MWeabs Posted June 9, 2009 Posted June 9, 2009 Hi all, new to the forum and loving all the knowledge. I was looking around for an answer to my dilemma and apologize if the solution is on here already. Anyway, I am modeling a handle for a project and I used standard modeling commands (extrude polylines, subtract, union, revolve, etc.) and the 2D wireframe looks right, but when I do the 3D hidden it gets all out of whack. CAn anyone shed some light on why this is happening? Thanks in advance. Quote
David Bethel Posted June 9, 2009 Posted June 9, 2009 Look into FACETRES and VIEWRES for control of smoothness. -David Quote
MWeabs Posted June 9, 2009 Author Posted June 9, 2009 Thanks for the tip, David. I adjusted both settings but it does not seem to change anything. Am I missing something? Quote
CADMASTER1128 Posted June 10, 2009 Posted June 10, 2009 Have you tried typing "REGEN" in the command line? Quote
MWeabs Posted June 10, 2009 Author Posted June 10, 2009 Yes I tried REGEN and no real difference. Also, I adjusted the FACETRES and then redid the model and I still get the jagged lines. I'd attach the file, but I can't get it below 500kb Quote
CADMASTER1128 Posted June 10, 2009 Posted June 10, 2009 MWeabs, Can you e-mail me the drawing file? I'll take a look at and see what I can do! shuseman2@gmail.com Quote
ReMark Posted June 10, 2009 Posted June 10, 2009 Could it be a graphics performance issue (see Performance Tuner) or a graphics card issue? Quote
David Bethel Posted June 10, 2009 Posted June 10, 2009 Is DISPSILH set to 1? What are the values you have for VIEWRES, FACETRES and SHADEMODE? -David Quote
MWeabs Posted June 15, 2009 Author Posted June 15, 2009 The DISPSILH was set to 0, but no difference when I changed it to 1. VIEWRES is 20000, FACETRES 10, and SHADEMODE is currently at 3DHidden, though I tried different SHADEMODE settings. CADMASTER1128 I mailed you a copy of the dwg, any luck with it? Quote
MWeabs Posted June 15, 2009 Author Posted June 15, 2009 ReMark, it could be a graphics performance issue. I was not aware of the 3DCONFIG command. I just checked it out only to discover that 'Smooth line display" is not available. This surprised me as I bought this computer less than 6 months ago assuming it would have no problem with AutoCAD. It's an HP m9510f with a NVIDIA GeForce 9500 GS card. Below is the info from the Tune Log: Driver : 7.15.0011.7578 Your machine contains a 3D Device that is not certified. As more graphics cards and 3D display drivers are tested, they are added to a list on the Autodesk website. You can check for updates and download the latest certification list at any time. Run the 3DCONFIG command and click the Check for Updates button. Current application driver: direct3d9.hdi Current Effect Status: ---------------------- Enhanced 3D Performance: Available and on Smooth line display: Not available Gooch shader: Available and using hardware Per-pixel lighting: Available and on Full-shadow display: Available and on Texture compression: Available and off Available application drivers and effect support: ------------------------------------------------- Software driver Effect support: Enhanced 3D Performance: Not applicable Smooth line display: Not applicable Gooch shader: Software emulation only Per-pixel lighting: Not applicable Full-shadow display: Not applicable Texture compression: Not applicable Direct3D driver: Not Certified Effect support: Enhanced 3D Performance: Available Smooth line display: Not applicable Gooch shader: Available Per-pixel lighting: Available Full-shadow display: Available Texture compression: Available Enhanced 2D Performance: Available So what I'm guessing is going on is I don't have the latest 3D driver for this particular card. However when check for updates through the Performance Tuner, I get a "Failed to update...check your network connection" window even though I am connected to the net. Any ideas? Quote
MWeabs Posted June 15, 2009 Author Posted June 15, 2009 OK, so I downloaded the latest AutoCAD 2009 update (v.3) and now my Performance Tuner says it is up to date. However when I view the Tuner Log, it still says last updated on 2/24/2009 (which, now that I think about it, was before the computer was ever used). And Smooth line display is still not available in Manual Tune. Now I'm wondering if I'm just missing the command to update the 3DCONFIG, or if I'm all updated and my card just isn't supported. Quote
MWeabs Posted June 15, 2009 Author Posted June 15, 2009 Well...after making that last post I opened 3DCONFIG again to see what I could be missing. I tried turning off 'Enable hardware acceleration' and to my surprise the handle is smooth! I'm not sure what turning that off did exactly, but I really appreciate the help on this. Quote
ReMark Posted June 16, 2009 Posted June 16, 2009 I think that by turning off hardware acceleration you put the emphasis back on the software to smooth out the display. Glad to hear you have a solution. Quote
