A:OZB:OXC:OY答案:AI参考:答案：B:OX。\n根据题意，投影线连接正投影和平面投影，垂直于轴线，而正投影和平面投影通常都垂直于OX轴，因此答案为B。'IspointKinlineAB?

答案:AI参考:正确选项是：No，pointKisnotinlineAB.\n\n解释：根据题目描述，我们需要判断点K是否在直线AB上。由于题目中没有给出直线AB的具体信息，我们无法直接判断。但是，从图片中可以看出，点K与点A、B并不在同一条直线上，因此可以得出结论：点K不在直线AB上。所以，正确答案是No，pointKisnotinlineAB。'InCATIAsoftware,thecommand

isusedto

?

A:gointoDraftingworkbenchB:gointoSketcherworkbenchC:drawcirclesD:drawarcs答案:AI参考:正确选项是【B:gointoSketcherworkbench】。\n\n在CATIA软件中，命令用于进入Sketcher工作台，Sketcher工作台是用于草图的绘制和修改的工具。而选项A、C、D都是与草图绘制无关的操作。因此，B选项“进入Sketcher工作台”是正确的答案。'Accordingtotheproj
