derklauer Posted February 11, 2015 Share Posted February 11, 2015 I am a proficient CAD user and attempting to use civil 3d (2015) for alignment sheets. Currently I am using the trial version and considering purchasing the program however I am having some serious performance rendering issues on basic alignment generating which make the program essentially unusable. Which is giving me some reservations on purchasing the program. I have a CPU that far exceeds the minimum requirements I seriously doubt this is how the program operates so am looking for some input. My data set is not massive. I have 22 mile alignment consisting of around 90,000 linear survey points xyz. The DWG when saved is 6.539KB The points imports in a relatively reasonable time frame 2-3 minutes. and im am able to connect them using the command "3dpoly line" + '_pn. However after I have the 3dpoly line it take about 3 minutes to select the line. and about 25 minutes to generate an alignment or a feature line. I have turned the "GRAPHICCONFIG" on and off and get the same results My system specs are proc: Intel® core i7 @ 3.5GHz 3.5GHz Ram: 32gb video card Geforce GTX 980 Quote Link to comment Share on other sites More sharing options...
JerryG Posted February 11, 2015 Share Posted February 11, 2015 Not sure what Operating system you are running but try here for a recommended driver for your video card http://usa.autodesk.com/adsk/servlet/syscert?siteID=123112&id=18844534&results=1&stype=graphic&product_group=3&release=2015&os=131072&manuf=all&opt=0 I looked but could only find the driver for the 9600. I use a Quadro FX 580 and had to go back a driver version (what autodesk recommended) to get the display to work correctly. Its still a bit slow but def not as bad as what you have described. I would also break the point file up into 4 or 5 different files and insert them one at a time. Quote Link to comment Share on other sites More sharing options...
derklauer Posted February 11, 2015 Author Share Posted February 11, 2015 Issue solved. The hang up is in the amount of vertices in the joined 3dpolyline. I ran the weed command and cleaned it up now it is running at a reasonable speed Quote Link to comment Share on other sites More sharing options...
