  1. Hi All

    first, thanks to Nicholas for going to all this effort and sharing it with us.

    I went to a seminar on rendering in Archicad, run by a very talented artist Dwight Aitken, and the basis of his whole argument was "think like a photographer". Have a look at the photo below;I assure you the walls and ceiling in my house are not Yellow/oragne. They are a pale beige.


    Dwight's theory is that the human eye takes "snapshots" of a scene, and the mind blends them all into a memory of the space. So you look into a dark corner, and your eye adjusts to the correct exposure, you turn to the sun, and a second or too later, your eye has adjusted again. For your render to look 'right' you have to trick the renderer by faking the dark areas etc.

    In Nicholas's excample, a professional photographer will add extra light to the scene to get the exposure correct in all the areas of the room. These lights are called the 'fill light', and the 'key light'.

    Dwight posts a lot here http://archicad-talk.graphisoft.com/viewforum.php?f=3&sid=51852861849d04a35e6732ec14ab5366 and although it's not a VW forum, you may learn something.


  2. Cinema 4d supports network rendering, and there's an exchange plug-in for VW.

    I used it for one project and it was quite successful and easy. I can't quite remember the workflow, but I think you upload the project to the server, (via web browser), then hit go. The server distributes individual frames to the other networked machines with the client software installed. So a slow machine might do one frame while a faster machine might do 6.

    Cinema 4d is easy to learn and produces a superior render to renderworks.

  3. I wonder (and I haven't tested this), whether going to Organize|Scripts|Vectorscrip Plug-in Editor, then pressing Done will regenerate all the PIO's in your drawing.

    Asumming your class was ticked to Use at Creation, (same for textures) then it might do what you want.


  4. Hi all

    I use the technique of laying one viewport on top of another to produce elevations etc.

    The top viewport set to hidden line render, sketch hidden line, and the bottom viewport set to open gl render (or fast renderworks etc).

    This produces a good drawing that the client seems to like, but, printing is SOOO slow.

    The following drawing took 40 minutes to print


    I printed to pdf995, but takes as long printing to epson color 1160.

    Anyone have any ideas?



  5. To get the last gable to show up, you could add a couple of extra points along that left wall.

    Pretend you are drawing another entire "wing", under where the gable is to go, but only make it 2mm deep.

    You may need it edit the original polygon you used to make the roof, the "create roof from polygon" again.

    It should be straight-forward.

  6. 1> Under the pan tool there is the move page tool.

    2> Under the views menu, when you save a view, there is the option to "save page location"

    It's to do with these two things, and to fix it, edit each saved view, and uncheck "save page location"

    That's if I've understood your question correctly.


  7. Hi Delmar

    I tried to replicate the problem with a new file, but couldn't. But I am not just dreaming, and I hope I'm not making some silly mistake.

    Here's the picture of the viewports classes dialog - click the pictures to see full size in a pop-up window;


    And here's when I use the standard classes dialog to control the visibility;


    Can you or anyone offer any comments? Thanks in advance.

  8. Hi All

    I'm having a silly problem with viewports and w.group references.

    Using the viewport class button I cannot control the class visibilities of two specific classes that occur in the workgroup reference.

    Yet, using the main class dialog, I can control the visibilites of the two classes.

    Is there a bug with viewports and workgroup references?

    Thanks in advance, Mat.

  9. Yhy don't you draw this shape, then extrude it?


    / \


    To give it thickness you could do an offset before you extrude, select everything and choose Tool | Decompose . Then you will need to draw two extra lines to conect each end. Then select all, then Tool|Compose, then extrude.

  10. Hi you guys, thanks for your help.

    Robert - if you have a minute, and a 'practice DTM', could you please check that you can change the border.

    Islandmon - I don't really understand, presumably you mean the 3dLoci on the dtm data layer? All I have is 3d polygons..

    Thanks in advance.


  11. Hi all

    I have used the "set border" command successfully, but now I need to change the border.

    I change the shape of the 2d polygon, select it, then run "set border", then update the proposed DTM, but it doesn't change?

    Should it change or does it only work once?

    Thanks in advance.
