@DuncanW posted a new topic, subject "Dimetric Projection". It read:

   Rhino seems to support isometric projection only. Is there a way to achieve dimetric or oblique projection?

    ### 3D projection
    
    A 3D projection or graphical projection maps points in three-dimensions onto a two-dimensional plane. As graphics are usually displayed on two-dimensional media such as paper and computer monitors, these projections are widely used, especially in engineering drawing, drafting, and computer graphics. Projections may be calculated mathematically or by various geometrical or optical techniques. Projection is achieved by the use of imaginary "projectors"; the projected, mental image becomes the tec...

    Following a recent similar question on this forum, I created a plug-in for axonometric and oblique views. It was very recently published on Food4Rhino: http://www.food4rhino.com/project/axonometric-and-oblique-views
    
    It is freely downloadable.
    
    I'm not sure exactly what you mean by dimetric projection. If you could point me to some math that explains it, I can try and see that this also ends up in the plug-in.

    Thanks for your reply.
    
    I have tried your plugin. It seems to have installed fine and shows in my plugin manager, but how do I choose oblique or axonometric projection when I'm in the top viewport? I clicked the dropdown menu next to “top” > set view > … _here you would find “isonometric”_ … and I thought this is where you had put the two new projections but I can't find them?
    
    In the wikipedia article I linked there's this image showing dimetric projection: http://upload.wikimedia.org/wikipedia/commons/4/41/Graphical_projection_comparison.png
    
    The angles are 105° 105° 150°. Would it be possible for you to add this? I'm sure your plugin works, I just can't figure out where to actually set the projections it offers. Thanks for your assistance!

    There are four commands:
    
      * Axonometric - this will enable/disable axonometric view transformation in the Top viewport. Geometry is not changed, only viewed in axonometric way.
      * Oblique - this will enable/disable oblique transformation in the Top viewport. Geometry is not changed, only viewed in oblique way
      * MakeAxonometric - select geometry to change to axonometric
      * MakeOblique - select geometry to change to oblique.
    
    
    
    Hope that helps

    Okay I've removed your plugin again, sorry. I need something that will actually modify the camera and how things are displayed.
    
    The usage of the plugin is too unintuitive. I can't seem to undo the projection. Anyway, I assume this means dimetric projection is impossible in Rhino.

So @menno (Menno Deij - van Rijswijk) replied

    Ok, too bad it does not work for you. You say you can't undo the projection - The _Axonometric_ command has an option “Enabled”. Switch this to yes/no to enable or disable the projection.
    
    I do not agree that it does not modify how things are displayed. It does modify how things are displayed, and uses the same method as outlined here  
    http://www.arch.virginia.edu/computing/training/online/pdf/Creating_an_Axonometric_View_in_Rhino.pdf
    
    That is, a rotation followed by shearing transformation.

Then @benjamin said

    Hi Menno.
    
    I appreciate this is an old discussion but I was wondering with your plugin if it's possible to get Make2D working, or saving as an illustrator file/vector pdf?
    
    I have had a play with it and managed to print as a raster however there are clipping issues, plus outcutting to scale in a vector format is far preferable.
    
    Cheers

    No, I'm afraid that is not how it works.
