Graphviz : seems to be a script-to-graphs translator, but the graphs look to restricted for what I need. I can't imagine how for instance to draw a picture clarifying a switch bounce. Intellicad: following the free download link did not lead to a download page. intellicad itself is a bit expensive for what I want at $240. serif draw plus: seems like it might do the job (.eps files are specifically mentioned). But at GBP 80 it will first have to wait for the free alternatives to fail. open office draw: seems like it can do all the drawing, but eps is not a native format, so I end up having one open office file and one eps file (for each drawing), and I must export to eps each time I change the drawing. And I don't see how I can have one master file for a bunch of eps drawings (like I can do in eagle with a bit of ULP). microsoft office: I have done a lot of drawing in word, but I found it a PITA. Also I see now way to save as vector format (but if it were easy and reliable to store inside a word document I would not have needed that). microsoft viso: looks nice, but too expensive. portable apps dia: wow, unlike open office draw I could actually make a simple drawing in 60 seconds! otherwise the same nitpicking as OOD: editing and exporting to .eps are separate steps. maybe the python interface can cure this problem, but it insisted on python 2.3, which is a bit outdated. I already have 2.5 and 3.0 in my PC, I am not sure I want yet another one. Conclusion: For simple drawings I'll stick to eagle, mainly because I like to have one master source document, from which I can export a bunch of .eps files with one command. For more complex drawings I'll try dia. -- Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: www.voti.nl consultancy, development, PICmicro products docent Hogeschool van Utrecht: www.voti.nl/hvu -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
