RogerC Posted February 20, 2014 Share Posted February 20, 2014 Hi, I just wanted to see if there are people here that are exporting (or linking)their models to 3ds Max to create renderings. We have been doing this for a while, but passing our models through AutoCAD, where we do some editing. Kind of tedious but we get decent results at the end. Like to see what others are doing and the results they are getting. Thanks & cheers Roger C Link to comment Share on other sites More sharing options...
Guest dialog Posted February 20, 2014 Share Posted February 20, 2014 Going through Autocad is pointless. Use either the FBX exporter from revit or depending on which version of revit and max you have, you can directly link revit files into 3DS max. If you are using older versions, FBX is the way to go. Gives you lots of options to work with. If your design is constantly changing, having a linked file is nice. Link to comment Share on other sites More sharing options...
RogerC Posted February 20, 2014 Author Share Posted February 20, 2014 Desmond, Do you use this workflow on a regular basis? Honestly we have used almost everything from Revit to 3ds Max directly and always have problems with the mesh. Link to comment Share on other sites More sharing options...
Guest dialog Posted February 20, 2014 Share Posted February 20, 2014 Yes we use this regularly. We have used this method on the Calgary Airport project for almost 3 years now. What we have found is that the linking is good during the design stage when the design is changing all of the time. When the designed is more locked, we bind in the FBX and start the cleanup, materials etc in Max. What issues are you having with mesh? What versions of revit and 3ds are you using?

RogerC Posted February 20, 2014 Author Share Posted February 20, 2014 The problems we have are mostly related to double faces and irregular geometry which is causing problems when we go to animate the models. Link to comment Share on other sites More sharing options...
Guest dialog Posted February 20, 2014 Share Posted February 20, 2014 Ahhhh yes... I have faced this many many times. The problem is whoever is modelling the revit... they need to make sure they are not making duplicates of things. Some of the files I have seen in revit or sketchup have 2-10 columns in the same spots. We came across the same issues in our animations and the only way we fixed it was to delete these duplicate objects, or in some cases extrude the face of the duplicated objects by a mm or two. There is a VRay setting I THINK that can help with this, but I have noticed it also kills render times. Link to comment Share on other sites More sharing options...
RogerC Posted February 20, 2014 Author Share Posted February 20, 2014 Well, we can't afford a slower render solution, as our render farm is slow enough as it is. We get Revit models, or exports from various companies. The quality varies enormously, but even the good ones still exhibit these problems. I'll see if I can come up with a concrete example and post it. Link to comment Share on other sites More sharing options...
Guest dialog Posted February 20, 2014 Share Posted February 20, 2014 Our solution has been to delete duplicate/coplanar objects. This takes a fair bit of time for the bigger projects. Link to comment Share on other sites More sharing options...
RogerC Posted February 20, 2014 Author Share Posted February 20, 2014 That'a basically what we are doing, but we pass the model editing through AutoCAD. Link to comment Share on other sites More sharing options...
paneli Posted June 8, 2014 Share Posted June 8, 2014 For me revit models always been a problem to render. Walls for example produce a lot of noise in render, even after I changed their structure in revit and left only the core. A similar Autocad model renders perfect, with exactly the same render and mat settings. I don't know what exactly is the problem, may be it's just bad karma or something.

Sauger Posted June 8, 2014 Share Posted June 8, 2014 Have you tried to export as DWG solids, just to test if it´s the FBX settings? I get very clean models(for game engines) using DWG, done many tests, same building done in MAX only differ 0-20% in vertices. You need to sometimes tweak the import settings if curved geometry (ellipses are not ideal). Suite workflow also can be set up to get very nice models to MAX, but I prefer DWG since not need any textures, or materials. Link to comment Share on other sites More sharing options...
paneli Posted June 9, 2014 Share Posted June 9, 2014 I use link and there not enough settings to tweak the geometry Link to comment Share on other sites More sharing options...
RogerC Posted June 9, 2014 Author Share Posted June 9, 2014 Yeah, we are still outputting to ACAD first. There are just too many things we do to the model to refine it in ACAD. It gives us better final renderings, so it's worth the extra effort. Link to comment Share on other sites More sharing options...

rbcameron Posted September 25, 2014 Share Posted September 25, 2014 I might be able to help you guys out a little. In 4 or 5 steps Revit + 3dsMax works pretty well. Here's the blog: http://mistressofthedorkness.blogspot.com/2013/11/revit-3dsmax-utilizing-render.html These are examples of Revit to 3dsMax of mine to view. I've had pretty decent success: http://www.turbosquid.com/Search/Artists/3d-medical-equipment?sort_column=A5&sort_order=desc Link to comment Share on other sites More sharing options...
