    Glass Symbols on Glass Elevations

    We've been using an angled pair of short parallel lines since I can remember as symbol convention to signify glass in facades / windows / shopfronts, etc. There doesn't seem to be an allowance for this in Revit; any ideas on this or is this convention going out of fashion ? Thanks, Kamran.

    If you really want it, put it as a surface pattern in Revit. But yeah, itll have to be a pretty tight pattern to make sure it hits every piece of glass, which means it wont JUST be two or three lines "per glass piece." Definetely an old hat tradition, i havent bothered since moving to revit. I use Material Tags on all my galzing anyway.

      In Revit, those symbols need to be created as Detail components, such as the two diagonal lines that traditionally represent glass, or the small arrows that indicate sliding panels, or the "X" or "O" symbols, etc. Then, you have 2 options: 1) Include those detail components in your window families, or 2) place them directly on your elevations, from the Project Browser, with Create Instance.

        I'd use model lines for this and nest into your family. This way you don't have to apply them in every window/door separately in your project and it's also visible when the view is non-perpendicular (which is not the case when using symbolic lines).
        Same use as the door/window rotation symbols.

        But on the other hand: I don't use the glass symbols at all. For me, they're relics of ancient times and fall in the same category as the discussion about insulation hatches that need to be perfect 30 degree triangles in all scales: not to be bothered with...

          Yeah, thanks for that; we had a facade engineering firm do a couple of projects for us and they work for the likes of SOM and KPF and they put millions of the parallel two lines symbols on their glass; recently we had a shop front in a mall with a 50% total opening (mall shop roller shutter) and 50% butt-jointed glass and we opted to put a large annotated dotted 'X' to signify where the opening and roller shutter were coming, then I remembered we used to signify glass with the symbol and that revit doesn't cater for that. I guess we'll have to decide what to do in future.

          Aaron, how do material tags look like on glass facades? Are you talking about, for instance, the window tags, etc. ? or something else ?

            No, a Material Tag that reads the material name. So they show up as GLS1, or GLS2. But, really, the symbol is doable as a surface pattern. It just shows up more than once, which isnt a big deal if youre "just trying to communicate" that its glass. It works perfectly. If youre trying to be artsy about it, then it night be less than ideal. I did the surface pattern thing at my old Revit office since they wanted the hash marks.

              Thanks Aaron, I might have a go at a surface pattern. We used to spend ages centering the symbols on the centre of windows, and separately on opening casements, etc., like you say in an artsy manner, but I like the idea of a repeating spread out pattern, just as long it shows up enough on smaller windows and doesn't look like decoration on larger ones.

                Our office has made the decision to show glazing as light grey in elevation. We just add the solid color to the glazing material. The hashes were preferred in the past, but this seems to make most people happy. You know... until something comes along that doesn't.

                  We used to do windows like that on elevations when we were using autocad. I think that's probably better than the hash symbol, thanks for that Mia. Kamran.

                    I have this pat file some time ago and it is used as a modeling pattern that mimic the glass hatch from Autocad, but if you decided to use it. make sure to scale it 144 times. and it should work pretty well.
