    Trees in realistic view RAC 2011

    Hello,

    I am working on a campus development plan. I am using a 3d top view to show the entire campus existing buildings,drives and parking layouts as well as our new modeled building. This is at a 1”=50’ scale everything shows up great in realistic view without having to render showing the necessary shadows and colors of the existing and new modeled buildings. That is after I modeled the roofs on the existing buildings the mass objects, I wanted to use for the existing would not show a shadow unless you clicked on the mass then they would shadow, but when you unclicked they would not show or print shadows might be a bug. I used a civil.dwg 2d for the existing layout as an underlay, this shows up in realistic view but not if you render.

    The main problem are the trees in realistic view, what is the best way to get a top view of a reasonable outline of a tree with a shadow? I have great looking shadows but no tree with the stock tree elements.

    All suggestions and help will be appreciated.

    James

    You would need to have a family with a decal on the top of it that looked like the tree in plan, then it would look good.

    Hey Scott,

    Thanks for the response. I am using the stock RPC Deciduous tree. I am not familiar with the term decal in Revit. I think I understand what you are saying, but have not been able so far to accomplish this. On the site plan level the deciduous tree shows a circle with several radius lines which represents the overall diameter of the tree and the limbs of the tree. I copied this deciduous base
    circle and added the Height parameter so it would always be at the top of the tree. It shows up in a ceiling plan view of the tree and elevations of the tree but so far I have not been able to get this circle base to show up in the realistic 3d top view. Do you know of any visibility settings that need to be changed for this to show up?

    Thanks for your help.

    You won't be able to use the stock content. Decals are jpgs or bmps that attach to surfaces. So you need to make a generic tree family with a flat round top, place the decal on that, its on the insert tab.

      Decal viewport visibility settings

      Hey Scott,

      Thanks for the response. I have a .jpg decal of a tree top in place on the campus 3d top view. Does anyone know how to remove the black line square & a line x from corner to corner with dots on the corners from the decal? This is acting like a viewport you can drag on the dots and resize the decal. When rolled over with the mouse it highlights and changes color. If I delete the square it deletes the entire decal. I have looked for visibility settings for this but so far have not found them.

      Thanks in advance,

      James

        Use the Linework tool and change the lines to Invisible Lines. Should work...

          Good day James.
          What is the relationship between the trees and the building elements?
          If you are not woried about NOT casting shadows on the buildings. A quick work around that we do in our office to save presentation times is to render the scene with just the trees and a coloured background. Export this as PNG.
          Then export a realistic view without the trees.
          Overlay the trees in a phot editing software. (photoshop)
          Hope this helps. have to admit that having more realistic trees (rendered) with the less detail model is a nice design effect.
          Going for the extra work in putting decals to all your trees and then having to edit all the lines after just seems like a lot more work than merging to images.
          Hope you can use this

            I suggest to put some SketchUp trees into RFAs, and use those. http://sketchup.google.com/3dwarehou...=m&btnG=Search

            What you find may need to be simplified some. You might want to keep those kind of plantings in a separate Workset because they can be somewhat heavy.

                ...Doesn't work...the lines displayed on a decal are not real, editable 'lines', but simply representative placeholders.

                afaik, the only way to get a realistic 3d view to display an image without those placeholder lines is to import -> image to your 2d view or directly to your sheet view. FYI, .tif files with a transparent background will maintain transparency in and around those non-rectangular images. (EDIT- i'm not sure about shadows with this method)

                I'm sure you're aware you cant import -> image into a 3d view, that's why decals were invented, for which you need geometry to place it on.

                You can also make a real material out of it, apply that to a surface and stuff around with it for ages trying to get your image displayed in the right spot, not fun, but rotatable. Just don't try a fly-by walkthrough with one of these in the picture, unless you want to movie-match every single frame. (ANOTHER EDIT- i'm not sure about shadows with this method)

                Revit is still very clunky with material manipulation, but is sloooooowly getting better. HTH.

                  I´m not sure that I understand excactly how you want the output, but here´s an idea to get a custom "realistic" looking tree in a 3D view.

                  Used one of the OOTB RPC´s, and added custom geometry to fake the RPC. To the new geometry and to the existing RPC I´ve added yes/no parameters to turn those on/of as needed. Also added custom materials for the trunk and crown (attached)

                  Hope it´s of some use... :coffee:

                    My bad, knew this could be done because, well I did it on several projects:
                    Decals are Generic Models, without any Subcategory. So if you go to Object Styles and turn the Generic Model linestyle white, this loses the lines... (well, actually they are still there and you will see them through the image, but they aren't that disturbing anymore).
                    Downsize: if you use other GM in your project, you'll have to make sure they all have been given a subcategory.
                    If not: you can always override graphics in View for the Decal, and change by Element to Edit the linecolor from there.
