第一次用AKE导出建筑立面。相较于原生的导出没有杂线，而且可以按照材质去分图层，每张图大约是30秒左右的时间，注意曲面需要柔化不然会出现多余的线.
First time using AKE to export elevation. Lines are clean compare to Sketchup Exported DXF file. It allow user to seperate CAD layers based on SU material SO that the window and the wall can be in different layers…
every elevation takes about 30 second to generate.
Notes: The curved surface needs to be smoothed to avoid extra line
