速写攻略基础篇男女比例
画速写是离不开形体结构的，不仅是形体要找准，结构更要重视，要理解内部结构支配着外部现象，结构是内在的，是最为本质的，这是我们能否画的扎实，到位的关键。

人体全身解剖知识
“在了解人体比例之后，还要学习人体解剖的基础知识。要了解头、胸、臀、颈、 腰、上下肢、腕、手、踝、脚的基本名称、形态及其在运动中的组合关系，但不必死记硬背过多生疏的细节和名称。了解人体艺用解剖是为了更理性地表达速写中的 骨点、转折和人体内部的结构支撑，这样可以使画面结构更加准确的同时，更能充实绘画内容。

人体局部解剖知识
1、人体头部解剖“头骨解剖：头骨，又称颅骨，它是由脑颅骨和面颅骨这两部分 组成的。头骨像容器，容纳着脑组织和眼睛，并且决定了头部的形状。脑颅骨接近于卵圆形，窄端是额部，宽端是枕部。脑颅骨形体简单概括，因此造型相对简单， 而面颅骨构成了面部的支架，因此起伏较大，结构复杂。

2、人体手部解剖“手部解剖：了解手部解剖知识对于速写中手的刻画和表现具有十分重要的意义。不了解手的解剖知识是无法准确表现出手的结构的，更不要谈画出手的“表情”了，因此画出手必须先从了解手部结构开始。

3、人体脚部结构“脚部结构：脚部的骨骼和肌肉与手部的骨骼、肌肉在形态上有相似之处，但又有很多特点。掌握脚部解剖知识对速写的了解和脚部刻画起着重要作用。

4、人体躯干及四肢解剖“人体躯干与四肢：人体躯干是速写训练中非常关键的内容，而四肢也是重要表现和刻画的内容。我们要准确把握相关知识并灵活运用。

衣纹如何处理?
对于衣服的褶皱，其实就是人体动态的外在表现。举个例子，当你转动自己的胳膊时，同学们就不难发现衣纹线会随着动态的变化而变化。对于美术生来说，如果你想画好褶皱，就要知道衣纹线里面的结构，以及它的动态。只有这样做，你的褶皱才不会显得盲目。因此处理褶皱很重要。

1.肩膀是衣服最重要的支撑这里用线时要强调三角肌的凸起。
2.画大腿时，用弧线体现出内部股直肌的形体
3.胳膊弯曲时，注意在伸肌组合褶皱的走向。
4.在肘关节大量衣褶穿插中。要能利用褶皱体现出肱二头肌

注意
必然产生的褶皱，是随着身体动态变化而变化，它实际上就是为了表现对象内在的形体。
偶然产生的褶皱，是衣服上偶然产生的线条，这些不是童鞋们要去刻画的重点。
同学们可以根据画面需要，比如疏密关系，进行适当描绘偶然产生的褶皱。
在此需要注意的是，速写的表现方式，大多是线描和线面的结合，这是根据你们的喜好而选择的。至于怎么画，大家要明白，衣纹线都是有起点和终点的。
