    Default about revit modeling

    i feel revit modeling is weak.other bim softwares apparently outdo it in this aspect.even archicad is better than it .(of course need aichifomula plugin).

    Be Patient. Revit is quite a good modeler. If you are speaking of "free form", then it is rather a mental exercise to get there, but not a real difficult one. Revit requires a new approach. Keep working to understand how the program models, and use the software in that manner.

    One of the issues in using Revit versus say AutoCAD. Is in AutoCAD you could draw something anyway you wanted. In Revit, although it is flexible, you really have to use the software the way it is intended, so it takes a little while of working with the software (or some very good training) to really understand how you feel the software can best be used.

    Keep those questions coming. We all worked through the initial Revit learning curve (and I'm still learning)..

    I personally find this kind of post very disturbing if you don't know the in and out of the software yet then it's better to ask question first rather than criticize it. Bashing a software without knowing what it can do is simply showing uneducated comment.

    I went through with the same process before but I asked questions rather than throw in some criticism and people around here are more than willing to show you what it can do and how it should be done.

    What specifically do you find weak? We need more information to understand requests like this.

    Do you mean creation tools or editing tools?

    Geometry creation for host objects like walls, roofs and floors? Creation of Geometric Forms (Extrusions/Sweeps/Blends/Revolves) in Massing and/or the Family Editor? The types of surfaces and solids that can be created? How you edit geometry?

    thanks,

    i touches many 3d softwares resulting from my interest.i can say revit is just revision of pro/e for building design.maybe its unique working way disguise its weak modeling..what i need urgently i surface modeling.but revit is blank for it.

    Why do you need surface modeling? If you can post an example of what you are trying to do.

    don't make the generalization that 'other BIM software' can model better. You mention ArchiCAD...ArchiCAD alone can't model anywhere near Revit. It takes a host of add-ons to make it do even simple operations, such as a canted, curved curtain wall, or stairs of any complexity.

    I think you would be more sucessful in your request to post examples. I've seen some very powerful modeling come out of Revit. My opinion is that you just haven't learned how to do it yet.

    While you cannot do traditional "surface" modeling ala Max lofts, nurbs surfaces, etc. you can create very complex architectural surfaces in Revit. For example, if you create a solid mass (whatever shape you want) you can then create a curtain wall system using just one face of the mass. Depending on the setting you use for the curtain wall system (mullions or not, thick panels or thin, glass etc) you can create any non-fabric surface you want. The best part is that you can turn the solid mass on or off at any time to make changes and update your surface. A tensile structure tool or catinary calculator would be nice but I haven't found an architectural surface that I couldn't create in Revit.

    (though my spiral shell tower still has some tough to model bumps in it.)

    Occasionally one runs into a task which would be difficult in any program. I have a roof (see this thread http://forums.augi.com/showthread.php?t=16382)which I think I could probably build in a more sophisticated modeling program. I would build the roof as a solid and then apply fillet radiuses to the edges. As it is I have spent way too much time trying to get it to look decent and will just draw it in with linework. I'm sure there are many improvements that can be made to Revit in the modeling department. Those will come in time, but only if people who use the program let the developers know that there are weaknesses. It may be unpleasant listening to a squeaky wheel, but sometimes it's the only way to get any grease.

    Jiaoyanbing,

    from your recent posts it is not clear what you are trying to achieve.
    Are you an Architect doing architecture ? are you an ID person doing industrial design ?, what exactly is your specific area of "interest " student ?, dabbler ?, a plant maybe ?


    If you are actually legitimate , you should already have done searches on this and other forums looking for information, seeking answers , looking at rendered / unrendered examples , downloading families to try and see how they have been constructed, looking at the questions and jpegs of people who are posting on forums here and elsewhere, read the help, looked for books and articles on the subject........
    And if you have done this, you would not be taking the line you of posts that you have been because you would have realized what Revit does and can do ...it sounds to me like you have a demo copy and are dabbling on a whim without wanting to do any work?


    People are very generous here, but you have to try yourself to work things out Rather than just say Revit can't do this or that - otherwise you might as well go and buy something else.

    Post Re: about revit modeling

    I feel Revit is not weak. So there... I have used several other packages over the years, cad, viz/max, formZ and archicad and sometimes to model something in revit you do have to learn a new way of doing it, but Frank Ghery is not using Autocad, archicad or any other software us mortals can afford, you can't use any traditional modeling software for his stuff, and he doesn't, he has a whole Batcave full of expensive toys. Nor I would not use Revit if I were George Lucas either. Revit is for Architects.

    One think I think a lot of folks here would agree on is that Revit has made more progress (in capability, usability, and compatibility) in the last three years that than any platform you can name, and can go head to head with anything you can buy without a prescription from a doctor. And is capable of doing any of the largest projects in the world (hello, freedom tower on line 3)

    It could absolutely improve: multiple profiles in sweeps, more modeling object types, you do have a point there- that there is only so much you can do with sweep, blends, extrusions, and revolves.
