Virgil Johnson Posted March 13, 2009 Share Posted March 13, 2009 (edited) I have a situation where the edges (building corners and window "cutouts") need a softened edge. Think of an adobe building with windows and doors inset into openings with rounded edges. I am working with a mesh model imported from Revit. Anyone know of a simple way of doing this? Virgil adding to this... I have used a mr material with special effects round corners. Actually I have two walls in the same place - one with roundcorners where I need them and one wall with the same material without round corners to give me straight lines where I need them. Works great but... the problem is how to get some kind of variation. Like a noise or displacement thing going. Some texture on the edges. Am I missing the obvious? -edited again I just discovered they put in something called 3D Displacement in the mr material. When did they do that? must have been in the last couple of minutes. Sneaky Autodesk. I have to quit starting work at 3 am! all I can say is duh and end this thread.

aaronrumple Posted March 13, 2009 Share Posted March 13, 2009 Why wasn't it just modeled correctly in Revit? Using sweeps, columns and void openings it it simple to model all these effects right in Revit. Then there is no fussing with the mesh in 3DS.

I am that idiot. Just a month into using it and I admit the Revit skills are a little weak. Facing a deadline at the moment so I have to limp along. But I promise to get better at Revit. But it is possible to sweep just some edges in Revit? I needed just some openings to have a roundness. So I if I made a wall with windows and doors just parts of the wall edges would be rounded. I tried a sweep in Max and unioned it to the wall. Worked all right but a little tedius with so many steps. v Link to comment Share on other sites More sharing options...
brynmor530 Posted March 13, 2009 Share Posted March 13, 2009 Can you post up any renders or screen shots? How big a sweep or curve do you need to the openings? It might help with suggestions if others who are better at this stuff than me knew just how big a curve to the opens you are after. Small slightly rounded and softened edges could be achieved at render but larger curves will probably require some mesh editing. Link to comment Share on other sites More sharing options...

Windows are from Revit but moved into the wall in Max. The material is mr with Special Effects radius of 2". The 3D Displacement map is a cellular. Still working on fine tuning.

aaronrumple Posted March 14, 2009 Share Posted March 14, 2009 Yes, in Revit you can sweep along a path or series of edges. You could use an in-place family (Modeling > Create > Pick a Category) You can model either a solid or a void. If you do a void and use the pick path option - don't pick an edge that will disappear. The sweep needs to be able to see the edge. Use cut geometry to subtract the void from the wall. Of course a solid doesn't need as many steps. To avoid a lot of in-place families and make things faster, you can create the curved geometry in the window family. This will automatically create the curves on each window you place. The attached was 100% Revit model. Link to comment Share on other sites More sharing options...
Virgil Johnson Posted March 14, 2009 Author Share Posted March 14, 2009 An excellent bit of work Aaron. I really am enjoying Revit. After drawing in Max for 15 years and 3D drawing in AutoCad even longer, I can see the depth of Revit. I suspect the next release will be a watershed for the program. Max is great for visualizations but Revit draws a true model. It clearly is the way of the future - or more like the way of the present. I will explore more. Thanks for the pointers.
