Now try to add a dependency from Transfer funds to Card identification : you can't. What is append ?
现在试着增加从 Transfer funds 到 Card identification 依赖性关联：你能吗？发生了什么？ Because you add the subject after Card identification, the subject is upper the use case and BOUML considers you try to do a dependency from Transfer funds to the subject.
因为你在Card identification 之后增加 subject, subject 在use case上面，BOUML考虑你试图建立从Transfer funds 到 subject 依存关系。 If you change the color of the subject this is more visible : 如果你改变subject 的颜色，可看的更明白。
Don't panic, contrarily to other UML tools you don't have to redo all, just call the menu of the subject and choose lower, and now you may add the dependency.
不要惊慌，相对其他UML工具，您不必重做所有工作，仅只须调用subject的关联菜单，选择lower，现在您可以增加依赖性了。
Zoom, window size, diagram format放大，窗口尺寸，图的格式 When you open a diagram the scale is set to 100% and the window size is unfixed. 当你打开一个图时，显示比例设为100%，窗口的尺寸不定。
When you change scale using the little arrows or directly writing the desired value inside the spin box (practical to come back exactly to 100%) the size of the arrows is unchanged, this allows to see them even with a small scale, and to not use a large area for that when the scale is hight.
当你改变比例时（使用小箭头或者直接在spin box写入值）[实际上是回到100%]。 箭头的尺寸不会改变，使之在小比例时可见，当比例较大时，一般不使用箭头

fit% change the scale to be the larger one allowing to see all the diagram elements depending on the diagram sub-window size. This may also be done choosing optimal scale in the diagram menu. fit% 使比例更大些，以便于看到图中的所有元素，比例的大小依赖于图子窗口尺寸。亦可在图的关联菜单上选择optimal scale 菜单项。
In the opposite you can automatically change the size of the diagram sub-window to see all the diagram elements for the current scale choosing optimal window size in the same menu or through the button . 与此相对，在关联菜单上选择optimal window size，或通过按钮
，
你能够自动改变图子窗口的尺寸，以便在当前比例下看到所有元素。
