Quick Sections

时间紧迫的时候，我就没有时间在 Kerkythea 里渲染一个完整的剖面图，这时我会用此方式使自己解放出来。事实上，我毕业论文项目的剖面图就是用这种方法来完成的，而且所有三张图我仅用一下午就完成了。该方法不仅提供了剖面本身的内部空间信息，而且也提供了建筑师的内部空间照明的目的。

使用这种技术的时候，重要的是要记住灯光的方向和它是怎样在不同表面的发散而成的。对于光线的问题，我当成是在阴天，所以会有更少的尖锐的阴影线和更加发散、柔和的阴影。

When I don’t have time to fully render sections in Kerkythea due to time constraints, I fall back on this method to get me out of jams. In fact, I used this method to create sections for my final thesis project and finished all three of them in an afternoon. This method provides not only interior spatial information by the section cut itself, but also the architects intent in lighting the interior spaces.
When using this technique, it’s important to remember which direction the light is coming from and how it will bounce off of different surfaces. I treat the light more like a cloudy day, so less harsh shadow lines and more diffused, soft shadows.



注意：
比例：该视频并没有解释比例问题，但是通常情况下，我也会导出 SU的剖面到 CAD 中。在那里，我将打印出部分PDF格式的文件来确定比例，然后在 Photoshop 里打开 PDF，我会重新调整渲染的剖面尺寸与CAD 导出的PD尺寸相一致。

线条操作：在视频中，剖面是在 Photoshop 里被填充的。为了得到清晰的线条，我们可以通过在 SU里填充的办法，当然也可以用在图片上填充的方法，就我个人而言，我认为这没有必要。如果做得正确，而且在Photoshop里有一个足够高的分辨率，看起来线会看起来不够锐利；另外一方面，涉及到修改的话，在 Photoshop 里进行线的处理可能会比较难。后面会讲到更多这方面的内容。

NOTES:
Scaling: This video doesn’t explain scaling, but typically, I would also export the SU section into CAD. From there, I would plot the file as a PDF to a predetermined scale then open the PDF file in Photoshop. I would then resize the rendered section to the size of the CAD PDF.
Line work: In the video, the section is poched in Photoshop. For cleaner line work, there are ways to poche in SU, and obviously in Illustrator. Personally, I don’t think this is necessary. If done correctly and at a high enough resolution in Photoshop, the line work will look more than sharp enough. On the other hand, in terms of editing, line work in Photoshop probably is not the way to go. More on this later.
