two measurements transfer

Good afternoon:
how to transfer two measurement-metric and imperial-including drawing and dimentioning.

AutoCAD drawings are dimensionless.  However, you can set your dimension style as imperial or metric.
If you want to convert the existing drawing creted with imperial unit length to metric unit (for example, 1 inch to 25.4 mm), you can use scale command to convert it.

是的。
你可在 modify dimension style 中的 alternate units 选项中，选择 display alternate units 。
标注中将有两种尺寸值。

有的图有两种尺寸,for example, holes is imperial, length is metric. your need set two, but when drawing hole using imperial, i found it is still metric, so it mustm be setting problem. it was happed in a interview. i don';t have autocad 2004 at my home. if you give me answer, it is will be great.

This must be a thread hole.  The thread is imperial, and the others are metric.  In this case, you should setup alternate Unit as imperial, the Primary unit as metric.  Make dimensions.  Then, double click the hole dimension, overwrite the dimension text with the imperial dimension.

借此贴问一下老师：
现在用 imperial 按1：1比例画一个图形，可上面有个 M24 的 metric 螺孔。这个M24的孔是如何按1：1的实际比例画出？
另外：这句 “Then, double click the hole dimension, overwrite the dimension text with the imperial dimension.”中的 overwrite 就是改写这个尺寸数值，如果这样直接改写的话，则数值不是精确的。这样理解对吗？
在三维中的转换能直接设定一个尺寸，Autocad不行吧。
谢谢！！！

You have to convert 24mm into inch (24/25.4).  Then draw the hole with this dimension.  The overwritten dimension text will not reflect the real size when you measure it in AutoCAD (not 24, but 24/25.4).

谢谢回复。
要手工计算啊。

not required

i guess you can try to use two different dimension style, and to modify one of the  style by change the sacle factor at primary units tab, of course it is cheating, but it works
