1、-作者xxxx-日期xxxx交通流线分析图解k【精品文档】交通流线分析图解I received a lot of emails asking if I could explain how I created the pedestrian paths diagram in the previous post. To generate the line work, there are many ways this could be done. In the past, I probably would have used the spline tool in CAD. The line work。

2、could also easily be created in Illustrator. However, not many people know about or use the pen tool in Photoshop. Its similar to the pen tool in Illustrator but with some minor differences. In this case, I will be using the pen tool to create a path that I can tell the brush tool to follow.很多人发邮件来问 。

3、我上篇博文中交通流线的分析图是怎么做的 。
交通流线图有很多种画法 ， 以前我大概会直接用CAD里的多段线画 ， 在AI中也很好画 。
但是很多人没想过或者是不会用PS中的钢笔工具 。
它和ai中的钢笔工具差不多但又有些微不同 。
这个案子中 ， 我会使用钢笔工具来画线 ， 并讲解笔刷工具 。
1. Setup the Brush settingsI need to first set the brush settings because this is what I am going to use to add a stroke to the path created in the next step. The setting 。

4、s in this step will determine the thickness of the line as well as the color, hardness, and opacity. I chose a hard brush, 6 pixels big, at 100% opacity, and with black paint. You may need to draw a few lines to determine if you have the correct size.1：设置笔刷首先要设置笔刷 ， 因为需要用笔刷描我下一个步骤中画的线 。
这一步的设置决定了线宽、颜色、硬 。

5、度和透明度 。
我选择了一个硬笔刷 ， 6像素 ， 不透明度100% ， 黑色（或者自己喜欢的颜色） 。
设置后可以画一段线看看尺寸是否合适 。
2. Setup the pen tool and begin creating pathsBefore choosing the pen tool, first create a new layer. The paths will not show up in the layers palette but the stroke that is applied to the paths will be drawn on this layer. Now, choose the 。

6、 pen tool and be sure the Path option is selected in the pen tool settings tool bar at the top.With the pen tool activated, begin drawing the paths. To create the curved paths, click and drag when choosing the points on the path. This will create handles that can be used to control the size and shap 。

7、e of the curve at that point.2.设置钢笔工具 开始画线在选择钢笔工具之前 ， 先新建一个图层 。
路径不会显示在图层面板 ， 但是描边的线会画在这个图层 。
然后选择钢笔工具 ， 确定路径是从顶部的钢笔工具设置栏中选中的 。
工笔工具就绪 ， 开始画路径 。
创建曲线路径 ， 选中路径上的点单击并拖动 ， 通过操纵杆控制曲线的形状和尺度 。
3. Stroke PathOnce you get the path where you want it, right click near the path and choose Stroke Path. If this option is grayed out,。

8、double check that you have the new layer selected that was created in the previous step.调整好曲线后 ， 单击右键选择“描边路径” ， 如果无法选择“描边路径”（文字呈现灰色） ， 双击上一步中新建的图层即可 。
A second dialogue box will appear asking what tool to use for the stroke. We want the Brush tool since this is what we set up in the first step. Then choose。

9、OK.To finish the path, hit the enter. Repeat these steps to create each path.然后单击“回车”一条路径就搞定啦然后每条路径都重复上述操作4. Generate many paths at different levels of opacitiesI want to create a hierarchy of paths revealing different levels of traffic intensity. This is shown through both a density of lines and le 。

这张图中 ， 我建了三个流线图层 ， 第一个图层不透明度是100% ， 第二个是50% ， 第三个是15% 。
5. Add line work glowI want the line work to have 。

11、 more of a presence in the illustration, so a slight glow will be added. This is done simply with the brush tool. I used a soft brush, 90 pixels big, and set the opacity to 12%. Where the lines are dense or converge together, I layered in some black paint.我想让这些线条更有体积感 ， 所以给线条加了一点光晕 。
笔刷很容易做到这个效果 。
我用了一个软笔 。

12、刷 ， 90像素 ， 不透明度12% 。
在线条密集或者相交处 ， 就在新建的图层上用黑色笔刷画一笔 。
