We used Adobe Flash for SCADA visualization in the past, but we want to move towards SVG for new web-based SCADA projects.
SCADA often uses the same, interactive symbols (like pumps, valves, ...) within the same document and with Flash I used to create a "Movie Clip" for such symbols/objects. Whenever I needed to modify a symbol I could simply modify it's Movie Clip and all instances of it automatically updated themselves in the same way. This was very handy.
Is something similar possible with Inkscape (or any comparable SVG drawing program)? I'm talking about drawing a symbol and create several clones (not simple, independent copies).
Answer
You can do something similar within in a single document, by using the clone tool.
You could for example draw all the originals shapes, put them in an area of the drawing (maybe on a separate layer, that you can show/hide),and then clone each object to use elsewhere (Edit > Clone > Create clone). When you edit the original element, all clones will be updated.
It's a workaround of not having a real "library" or "palet" of symbols like in Illustrator.
I'm not sure if it's possible to make clones work accross different documents though.
