Xcircuit

有绘图程序，也有原理图采集程序。所有原理图采集程序都能生成可用于出版物的输出。然而，这些程序的目标各不相同，这一点显而易见。原理图采集程序的输出很少真正适合出版；通常甚至无法读取，或者无法缩放。真正想要获得有用的电路原理图的工程师通常会在通用绘图程序中重新绘制电路，这既繁琐又容易引入新的错误。

XCircuit 非常灵活，可以用作绘制几乎所有内容的通用程序，并且与“xfig”等功能强大的程序相媲美。它尤其适用于任何需要重复使用一组标准图形对象的任务，包括建筑绘图、印刷电路板布局和音乐排版。

There are drawing programs, and there are schematic capture programs. All schematic capture programs will produce output for inclusion in publications. However, these programs have different goals, and it shows. Rarely is the output of a schematic capture program really suitable for publication; often it is not even readable, or cannot be scaled. Engineers who really want to have a useful schematic drawing of a circuit usually redraw the circuit in a general drawing program, which can be both tedious and prone to introducing new errors.

XCircuit is flexible enough to be used as a generic program for drawing just about anything, and is competitive with powerful programs such as "xfig". It is especially good for any task requiring repeated use of a standard set of graphical objects, including architectural drawing, printed circuit board layouts, andmusic typography.
