几周前偶然发现了纸卷装饰画的概念后，一个念头突然闪现在我的脑海：怎样将数码化转化成独特的建筑表现图，以用于营销或者作品集。这种风格看上去很棒，我知道SketchUp有一些插件，可以让工作流程变得很简单。专业版的 SketchUp就可以，它可以导出和导入 AutoCAD 文件，这个“Tig”插件叫做“沿矢量推拉边缘”。

I came across the concept of “quilling” a few weeks back and instantly began thinking how could I translate this digitally to generate a unique architectural illustration for marketing or portfolio purposes. The style had a great look to it and I knew that Sketchup had some plugins that could make the workflow really simple. All you need is Sketchup Pro so that you can export and import AutoCAD files, and the “TIG” plugin called “Extrude edges by Vector”.

1. 第一步是将Sketchup模型的一个场景以 2D AutoCAD 线框模式导出。我上面也讲过了，需要专业版的 SketchUp，因为专业版的软件能确保成功导出 AutoCAD 文件。在 SketchUp 中，选择“文件>导出>2D 图形”。在导出对话框中，将导出文件类型设置为“AutoCAD DWG”，然后导出。

1. The first step is to export a view of the sketchup model as 2D AutoCAD line work. As I mentioned above, you need Sketchup Pro to be able to export  AutoCAD files. In Sketchup, choose “File>Export>2d Graphic”. In the export dialogue box, set the export type to “AutoCAD DWG” and then export.

2. 接下来打开一个新的 SketchUp 模型，导入前面导出的 AutoCAD 文件。选择“文件>导入”。在导入对话框中，确保文件类型设置为“AutoCAD文件”，选择 AutoCAD 文件的位置。然后导入文件。

2. Next, start a new Sketchup model and import the AutoCAD file that was just exported in the previous step. Choose “File>Import”. In the Import dialogue box, browse to the location of the AutoCAD file making sure that the file type is set to “AutoCAD Files”. Then import the file.

3. 当几何图形被导入后，下一步是沿垂直方向推拉。SketchUp不能推拉线条，所以我们需要插件来完成这个操作。能实现这个的插件有很多，但是“Tig Extrude Edges by Vector”插件确实很好用。这个插件可以选择多段没有连接的线条，并在任意方向推拉它们。

3. Once the geometry is imported, the next step is to extrude it vertically. Sketchup does not extrude lines, therefore a plugin is needed. There are many out there, but the TIG Extrude Edges by Vector seems to work really well. This plugin allows you to select many edges that are not connected and extrude them in any direction.

使用插件后，得到的结果是一系列像纸条的平面。

Once the plugin is applied, the result is a series of planes resembling strips of paper.

4. 最后一步是将视图设置为俯视图然后渲染模型。我在 Photoshop 中微调了下颜色，添加了一些较浅的纹理，得到了最终效果。

4. The last step is to set the view to “Top” and render the model. I then tweaked the colors in Photoshop and added some light textures to achieve the final look.
