    Default Surface disappears when rotating in 3D

    I have a surface of an existing street that is 400 feet long.
    when i select the surface and go to object view it displays fine, but the moment i try to rotate the surface in 3d it totally disappears.
    have no clue why.

    The pivot point is probably not in the center of your model, that is why it "shoots off".

    Try setting it to a 3D point using 3DORBITCTR

    I think it was 2017 where they fixed this to better "guess" the pivot point.

    the 3d orbit types a little practice it probably went of screen somewhere, but just in case check the display settings I set my on conceptual personal preference

    i tried the 3dorbitctr, but it isn't available in object viewer. i could only see the linework, not the surface triangles or shading.
    using conceptual style, it shows up while I'm rotating it, but as soon as i let off of the mouse it disappears.

    i just created a rectangle, created a feature line, and a surface in the same drawing and it displays fine, just the way it should.
    must be something with that surface, but have no idea what.

    edit: it seems if i have a style of contours and triangles only, the object viewer displays it correctly.
    any other style will not display, just disappears

    Surface styles have an area for what to display in a model (orbit) view direction.

    Edit the surface style, go to the display tab, select the view direction of Model. Now select the surface component types you want to see when viewed like a model.

    The object viewer allows you to select the pivot point, but in my testing, it doesn't work very well.

    See this discussion on it, and this screencast.
