我们从某一角度观察一个物体时,所看到的图象叫做物体的一个视图.从正面得到的视图叫做主视图,从上面得到的视图叫做俯视图,从左边得到的视图叫做左视图.主视图、俯视图、左视图三者合在一起叫做三视图.本文谈谈与一些小立方块搭成的立体图形相关的三视图问题.一、由立体图形画三视图1.画主视图规律:主视图中每列从左到右的正方形的个数就是立体图形中每列从左到右的小立方块的层数.
When we look at an object from a certain point of view, the image we see is called a view of the object, the view from the front is called the main view, the view from above is called the top view, and the view from the left is called the left view. , Top view, left view of the three combined together called the three views.This article talked about with a number of small cubes three-dimensional graphics of the three-dimensional problems.First, the three-dimensional drawing by the three views of a painting main view of the law: the main view The number of squares in each column from left to right is the number of small cubes from left to right of each column in the solid graphic.
