Exporting Revit models for other rendering engines

[pashley]

If I wanted to render a Revit model in VIZ or some other rendering app, to what format would I export the model? Can this even be done? If so, what are the drawbacks?

If exporting is possible, can walk-throughs be created from the imported model if the importing program has that ability for its native files?

The basics will apply to other rendering programs also.

I export the 3dview to an Autocad drawing and import that into 3dMAX.
I have successfully exported to 3dsmax 5 and 6. You can also bring in
models from MAX but there are problems:

The attached files are 3dsmax 5.0 images exported to Autodesk dwg format. Note that the dwg and dxf file was taken directly into Revit 5.1 via dwg and a separate project imported dxf. You can explode the imported dwg, but the dxf is erased if exploded. (Tried that to try and get the section to work).

In plan view you only get a "site" or top view, no matter the layer.
In elevation you get any image you chose, as you do in any camera view.
However, sections ONLY show the elevation, no wall thickness etc.

The file is De Espona's Bankhaus model which means I cannot post the model for you to play with. The attached images are the original 3dsmax base image, dwg image - rendered with no models and wireframe, and one image shaded with edges of the dxf model.

I'm printing out the Adesk material myself to see if there is anything hidden there to help into MAX. Biggest problem is the material changes...

A bit more info -The base image is Max 6.0 :lol:

hi,guys.I regist today and come from China.
I completed a project using revit 5.1 but I find it is difficult and puzzle that exporting revit modeling to the max6 file.
we can extport .rvt to dwg after setting the export setup according to autodesk's revit whitepaper. and importing the dwg file to 3dmax6,my god,the same style object turn a block.For example. in revit,different style wall is independence,I can specify a material to a wall,but in 3dmax,
all walls is a object composing.I must break away it spending many time.
It is crazy when so many walls in your project. More over,all revit element will miss the problem.
How should I do?autodesk must tight the connection of revit and 3dmax.

It's one of render images of my project.

I have the same problem going to Max from Revit, so I have focused on using Accurender as best I can. The Revit Accurender has some limits, but is quite capable. I posted two images on the Image of the year award area, check them out -( removed from post- rp) both are Accurender only images. (no touch up with Photoshop). Only draw back is that they took over 6 hours each to process. What about your image - is it Accurender or Max?

When I was first starting in Revit, I modeled a project in Max and then documented it in Revit. Attached you'll find the images resulting. I have not attempted to update the final Revit model for presentation, but Revit was an excellent tool in proving the concept. After seeing what could be done with Revit, I have focused on seeing how far you can take the Accurender shipped with Revit. Hopefully the version will be updated to Accerender 3.5 so the RPC 3.0 files can be used.

The white paper you mentioned brings up another learning curve to focus on setting layers and colors in Revit to take advantage of Max. Just something else to learn... :roll:

Thank your reply for my question!I try to use Accurender to render my images before.but the result was so bad! Accurender raytrace render engine can't compare with max standard render,its global illumination is very slow and lack detail.If you used finalrender or mental ray,you should throw Accurender away:)
The image I posted was rendered with Max6.0+finalrender stage1 sp2.It have 4000X3000pixel and it took me 20 minutes.The effect and speed was very satisfiable.
Yes,revit is good tool for realizing the concept,it carry more interesting than other cad tool. Autodesk ins. should intergrate 3dsviz into revit as they did it for ADT.

By the way,I find a tip of export revit model to max.If you export rvt to dwg,you will have a model making up of 3dface. but you export rvt to 3ds,then import 3ds file to max, ok,the model is composed of 3dmesh.
you can detach the element you will especial material.It is more easy to deal than 3dface.

the image was rendered by finalrender too.

Got Final Render 2, but haven't learned it yet - looks like I need to. Nice lighting. Another fun one if you haven't explored it is Dreamscape 2..

Where did you find the 3ds export on Revit? Or do you mean throwing it to Autocad as a dwg and then saving it to 3ds?

finalrender is very easy to learn. It can render beautiful image even if you use standard setup.
yes.You must export .rvt to .dwg,then save it as .3ds using autocad.
