感谢3楼4楼的热心帮助。名字我查词典可以找到，可是不知道其真正的含义。

非常感谢楼上，真的很感谢，我英文一般，贴出来大家共享。预知详细，请到楼上老兄提供的网页。

Isometric

Isometric projection is one of the three forms of axonometric projection. In isometric projection the angles between the projection of the axes are equal i.e. 120[$ordm]. It is important to appreciate that it is the angles between the projection of the axes that are being discussed and not the true angles between the axes themselves which is always 90[$ordm].

Trimetric

In trimetric projection the projection of the three angles between the axes are unequal. Thus, three separate scales are needed to generate a trimetric projection of an object. The scales are constructed using the same method described in isometric and dimetric projection. An example below shows the method of construction for each of the scales.

Dimetric

The angles between the projection of the axes in dimetric projection renders two of the three to be equal. To draw the outline of an object in dimetric projection, two scales are required. The scales are generated the same as for isometric. An example of how to construct the two scales is shown below.

130+130+110=370

看不懂E文，哪位能否解释一下
