matthewbrewer Posted December 3, 2015 Share Posted December 3, 2015 Hi all, I'm trying to model a building from CAD plans I've brought into Max using the snaps toggle 2.5 to draw over the CAD with the line tool and then extrude. The problem that I'm having is that the accuracy of the snap isn't aligning with the CAD line correctly. I've turned off all the snaps except for end points, but when I extrude it seems to jump slightly. I'm creating a model for council DA and if they find misaligned edges they reject the submission and you end up spending ages going over the model finding the walls that don't line up. I figured out it was to do with the snapping and I was wondering if there was a way of making the snap line more accurate? Thanks guys Link to comment Share on other sites More sharing options...
jonathandewitt Posted December 4, 2015 Share Posted December 4, 2015 Are you sure you're at the origin (0,0,0)? The farther you are from it the less accurate the accuracy becomes. Link to comment Share on other sites More sharing options...
matthewbrewer Posted December 4, 2015 Author Share Posted December 4, 2015 Yeah thanks, I'd set the origin to 0,0,0 first. I still don't know what causes it. Link to comment Share on other sites More sharing options...
D C Posted December 4, 2015 Share Posted December 4, 2015 Have you taken the drawing into a CAD program and cleaned it correctly? Try resetting the xform on the drawing in max too. Link to comment Share on other sites More sharing options...
CliveG Posted December 5, 2015 Share Posted December 5, 2015 I'm no guru, but this isn't the way I'd go about this. I've always felt the Max snap to be inferior in a lot of respects to AutoCAD snaps, not least accuracy, though the 2.5 feature should be a feature available in AutoCAD. (In fact AutoCAD snaps were even better yet in versions about 15 - 20 years ago now, but that's just showing my age) Work on your file import parameters and just reference and bind the AutoCAD geometry and extrude that. Earlier comments about 0,0,0 should be adhered to as well. This is pretty easy, reliable and accurate. If there are lots of curves you should take a bit more time fine tuning spline settings both in AutoCAD and MAX importing. What hoses me off is that once upon a time these were two flagship products from the same company, why could they not have used similar interface & algorithms then? Obviously now they don't give a rats___e. Link to comment Share on other sites More sharing options...
matthewbrewer Posted December 8, 2015 Author Share Posted December 8, 2015 Thanks guys I'll give that a go and see if cleaning it up in AutoCAD first works. Link to comment Share on other sites More sharing options...
Chris MacDonald Posted December 8, 2015 Share Posted December 8, 2015 This comment will be entirely unhelpful, but max snaps are awful. In fact most viewport related stuff in max is awful. The best I've ever used are Sketchup snaps. AutoCAD and Microstation are damn good too. Link to comment Share on other sites More sharing options...
