用于绘制透视的渐变式画框
来自 arteascuola.com 的两份可打印 PDF 练习页，适用于绘制一点透视或两点透视，仅需三角板即可完成，无需其他技术制图工具。该练习页带有刻度式画框，可辅助绘制透视中的所有垂直线与水平线。确定地平线及消失点（或两个消失点）后，即可利用印在纸张边缘的毫米刻度尺绘制透视。
图中展示了如何利用这些练习页分别横向与纵向绘制若干透视图。绘制一点透视时，只需画出地平线、消失点及纵深方向的透视线，所有垂直线与水平线均可借助毫米网格轻松完成。下方是一幅以胡安·米罗为主题的博物馆设计图，配有“巨幕”纪录片展示效果。
此处为两点透视示例，同样借助毫米刻度画框，使垂直线与水平线的绘制更为便捷。

Graduated frame to draw a perspective
From arteascuola.com two printable pdf worksheets, they are useful for drawing one-point or two-point PERSPECTIVE, using only a set square without the need for other tools for technical drawing. The sheet has a graduated frame that allows you to draw all the vertical and horizontal lines of the perspective. Once the horizon line and the vanishing point (or the two vanishing points) have been established, the perspective can be drawn using the millimeter rulers printed on the edges of the sheet.
In the images, you can see how to create some perspectives with these worksheets, both horizontally and vertically. To draw the one-point perspective just draw the horizon line, the vanishing point and the depth lines, all the vertical and horizontal lines will be facilitated by the millimeter grid. Below is a drawing of a museum dedicated to Juan Mirò with a documentary on the “giant screen”.
Here is an example of a two-point perspective, also here the drawing of the vertical and horizontal lines is facilitated by the millimeter frame.
