Wow. Very serviceable FREE application.
Currently at version 1.7.1, the symbol libraries are great--no moving fixtures, but that's okay with me. The database side of things is very good in general. I couldn't find a way to edit in a list view though, with sortable columns and multiple selections. It may be there somewhere, or perhaps some other means of editing data for groups of symbols meeting some criteria. There is even a database field for "Group," though no apparent way to select all the members of say, the Cool Torms group and change the color for every instrument. It's either a deal-breaker or I'm just being stupid. Doing this graphically, in the plot window, works very well but isn't always practical after the first hundred instruments. Heck, the first fifty instruments. The documentation is a little old and occasionally references material in later chapters without making it explicitly clear that you haven't read something yet, but we're talking about it anyway. A fix might be as simple as reordering a few sections.
The plot side of things is a little messier. Don't get me wrong, LXFree will make absolutely beautiful plots. I just think getting there is harder than it needs to be. Man I want a Hand tool. Or some other means of navigating around a plot. Command + Arrow maybe. (The Arrow keys without a modifier nudge selected symbols around.) It is hard to select an entire instrument symbol sometimes. One ends up accidentally moving only the color label or circuit number. I think they should be grouped by default, and one should see a larger indication that you've got the whole symbol selected without having to zoom way in. It would also be great if the user could set default preferences for symbol attributes--which legends are showing, relative positions of the labels, et cetera. This may not be a problem if you always work from templates, always recycle old drawings or simply like the default settings. The duplicate array function does not accept negative values or y-axis offsets. No radial arrays, but how often do you find circular grids? Isn't that even an oxymoron? Anyway, arrays and some other drawing commands are executed in an inspector window panel and not in the menus where they could easily have keyboard equivalents. One could then duplicate symbols without ever having to navigate away from the symbol info panel in the inspector. I'd love to see a GUI means of linking instruments to particular hanging positions--Option + drag or something. The layer function works well and there are enough drawing tools to make layers with Acting areas, rough sets, seating plans and so forth. A few chair symbols might be handy at times. The coloring of instrument symbols vis a vis the gel color is gorgeous.
All in all, a good tool with room to grow, well-suited to smaller projects. And, it's FREE.
