    2d linework order

    Hi all,
    Please see attached. In plan view i have chairs arranged around a table, the chairs should disappear under the table top as arranged.
    However the linework is still visible with the chairs over the table!
    Chair and table are 3d modeled - no elements visible in plan and relying on symbolic lines and masking areas to provide plan view.

    How do i make the chairs disappear beneath the table top?

    Many thanks!

    Dave

    It might be that the chairs are detail elements with a masking region in the chair family [with the model elements visibility unticked] and they are masking the model element table. The way to check would be to check in the Ref.Level view of the chair family.

    Hello, I've took a look into your families and the problem is very easy to solve actually, you just need to open your chair family and in a 3D view you need to select the geometry and by hitting the Visibility replacements (Sorry if this is not the exact term, but my Revit is in French) you just select the visibility parameters dialog box and check the box called Plan/Ceiling Plan (See images) this will active the geometry to show in plans, let me know if this works for you, regards

    and the problem was due to: "the chairs are detail elements with a masking region in the chair family [with the model elements visibility unticked] and they are masking the model element table". as @ Kamran Mirza already tell you in his post!

    Issues like this really make me wonder if its time to give up on Symbolic Lines.
    Do they really serve much purpose anymore?
    There was a time and place for Symbolic Linework when we had slower processors and 4 Gig of memory, but isn't any machine capable of running Revit capable of doing the 3D hidden line calculations these days?

    I gave them up in 2009. There is no place for them anymore, and hasnt been for a long time.

    Back then the issue was the wimpy graphics cards, not the processors.

    Thanks Andres and everyone for your help!

    I did as you said and it worked. I learned it that i have to use symbolic lines and masking regions and they would stack in order based on their position with the model (hence table would mask chairs).

    Just so i understand this correctly:

    • There is no reason to use symbolic lines and masking reasons anymore - it was just a performance thing and now processors are up to job.
    • Use the 3d geometry whenever possible.
    • Use symbolics v sparingly as no way to control stack order.



    Regards

    Dave
