在A點(diǎn)之左5mm,
坐標(biāo)為(10,15,15)
A點(diǎn)之后5mm,
坐標(biāo)為(10,10,15)
A點(diǎn)之下5mm,
坐標(biāo)為(10,10,10)
所以
B點(diǎn)坐標(biāo)為(10,10,10)
已知A點(diǎn)的坐標(biāo)為(15,15,15),B點(diǎn)在A點(diǎn)之左5mm,A點(diǎn)之后5mm,A點(diǎn)之下5mm,求作A`B兩點(diǎn)的三面投影.
已知A點(diǎn)的坐標(biāo)為(15,15,15),B點(diǎn)在A點(diǎn)之左5mm,A點(diǎn)之后5mm,A點(diǎn)之下5mm,求作A`B兩點(diǎn)的三面投影.
