Rotations "do not appear"/are "not reflected" in Wireframes

    A user posted an the following observation (with different wording but with the same meaning) in another thread. However, this really needs its own thread, so here it is.

    Objects inserted from the Library, including fixtures and truss, sometimes do not appear rotated in Wireframes (regardless of mode). It makes no difference how the rotation is/was performed, i.e. with the Rotate or Rotate in Place commands, or driven by a Rotation Axis or a Frame; the objects always appear rotated correctly in Shaded Views.

    This is true, and here is why: by default, WYSIWYG's Wireframe views display Symbols for Fixtures, Truss, and any and all other objects inserted from. Symbols are two-dimensional objects which only exist for Plan, Front/Back and Side Views--and not for every conceivable "in-between" angle (it would be a nearly-impossible task to draw so many such Symbols).

    It is therefore normal, for example, for an object that's been rotated less than 45º in Plan view (so around the Z-axis) to appear as if viewed fully from the front in Front/Back views. Similarly, should the same object be rotated more than 45º, it is normal for it to appear as if viewed fully from the side in Front/Back views.

    In order to see the object "properly", all you need to do is disable the Show Symbols option, which causes Wireframes to switch from displaying Library Objects' Symbols to displaying their 3D model. You may do this for the entire file at once (i.e. all Wireframe views, in all modes) via Document Options > Wireframe Details tab, or for individual Wireframes from their View Options > Wireframe Details tab.

    For more information about Symbols, please consult the Symbols section of the WYSIWYG Reference Guide.


    Cheers,

    Dany

    As the offending party, thank you for the explanation. I am a bit at a loss as of why it isn't possible to do a rotation transform on the sprite in the CAD view though, to at least display the most obvious of the rotational axis.

    To put it into context; if I add an GLP impression X4 bar 20 to a vertical truss piece, this is displayed horizontally. Quite annoying. I would think that this could be solved by doing a rotation transform quite easily based on the orientation of the hanging structure. Or would this require an additional sprite for a vertical version of the x4 bar?

    Does this also mean that for every item added in CAD view, there are separate entries for it for all the different views? Or is there at least a "flip" transform applied to the L/R or F/B views?

    Not a problem Martinus, and no need to apologize. :) I just really didn't want this to get lost within the other thread, as I said.

    Yes, every item in the Library that can appear in 2D Wireframe Views (so everything except Colors (Gels), Gobos, Bulbs and Lenses) consists of separate 2D symbols for Top, Front/Back and Side Views. In addition, Library Items contain a 3D model, which is used to show them in Isometric Wireframe Views and in Shaded Views. Therefore, to answer your question, no, we do not apply any kind of transformations in order to view things from different 2D viewpoints.

    I do not know if such transformations are possible to apply in order to improve efficiency and visuals, but I will discuss this with our development team, and if it is, perhaps it will be something to tackle in the new year. (This would be a rather major undertaking of course, but may very well be worth it.)


    Thanks for opening this discussion and for your idea! :)

    I would like to add to this: with some fixtures (e.g. Clay Paky Glow-up) inserted on the floor, even the insertion height seems to be different depending on having view as symbols switched on or not. If you insert them at floor level as a symbol, they appear to be on the floor (in side view). In reality (ehm... or virtual reality) the fixture hovers above the floor. If you switch to look at the fixture as wireframe, you see the correct height.

    Thank you for the reply Dany! Appreciate the insight into the workings of wyg.
