A:OZB:OXC:OY答案:AI參考:答案：B:OX。\n根據題意，投影線連接正投影和平面投影，垂直于軸線，而正投影和平面投影通常都垂直于OX軸，因此答案為B。'IspointKinlineAB?

答案:AI參考:正確選項是：No，pointKisnotinlineAB.\n\n解釋：根據題目描述，我們需要判斷點K是否在直線AB上。由于題目中沒有給出直線AB的具體信息，我們無法直接判斷。但是，從圖片中可以看出，點K與點A、B并不在同一條直線上，因此可以得出結論：點K不在直線AB上。所以，正確答案是No，pointKisnotinlineAB。'InCATIAsoftware,thecommand

A:gointoDraftingworkbenchB:gointoSketcherworkbenchC:drawcirclesD:drawarcs答案:AI參考:正確選項是【B:gointoSketcherworkbench】。\n\n在CATIA軟件中，命令用于進入Sketcher工作臺，Sketcher工作臺是用于草圖的繪制和修改的工具。而選項A、C、D都是與草圖繪制無關的操作。因此，B選項“進入Sketcher工作臺”是正確的答案。'Accordingtotheproj
