这个插件给我们提供了一种其它的方法来生成平面图，特别是在3D模型是完整的情况下。SKETCHUP平面图里的阴影并不是非常自然。阳光经由模型被剪切的部分进入。这种生成剖面图的方法保留了逼真的阴影。

The plugin gives me an other way of making plans. Especially in those cases where a 3d model is complete. Shadows in Sketchup plans are not very natural. The sun enters by the cutted part of the model. This way of making the section preserves the realistic shadows:

Rendered SectionByCamera (Twilight + Kerkythea)

It works also on Mac. Thanks Peter (pbacot) for testing.

For the SketchupTeam : realistic shadows in sections (plan en vertical section) is in my wish list.

UNZIP and COPY in de plugin-directory:

IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

Description :
This tool places the camera in (near) the sectionplan. The parallel view will section the model (without section cuts active). But the SHADOWS of the entire model will be displayed (if section cuts are switched off). This will produce a plan or section view with realistic shadow information.
The camera-position is saved in a new scene called "SectionByCamera"
The generated camera should also work with those renderers :
- Twilight : OK
- Kerkythea, with Twilight exporter
- SU2KT from Tomasz : The camera is moved, outside the model : Doesn't work.
- Maxwell : shadows not correct, shadows of 'ceilings' are missing. Thanks Peter (pbacot) for testing .

Installation :
- unzip and copy the unique file into the plugins directory

Usage :
- select a section plan
- in the context menu : select 'Section by camera' > '.... automatic'
or 'Section by camera' > '.... define camera distance'
- switch off the 'section planes' and 'section cuts' (Menu : View >> Section...)

Known issues:
The image rendered on the screen is cutted some centimeters before the camera. The distance between this 'cut' and the camera depends of the dimensions of the model. The tools estimates this distance (in '.... automatic'; distance proposed in '.... define camera distance'), if necessary, it can be adapted in the second option.
If the applied value is to small, the SectionPlane won't be visible after activating the tool. This is also true for faces generated by plugins like SectionCutFace (TIG) or realSection (GWydouw).
SOLUTION : apply a greater distance in '.... define camera distance'

History: First version

使用方法：
1.添加剖面，右键剖面，一般选择自动即可。

2.取消查看菜单下的“显示剖切”和“显示剖面”前的对勾。
