Watermarking a Model为模型添加水印

In SketchUp, the Watermark feature can place a graphic in front of or behind your model. 在SketchUp中，水印功能可以将图形放置在模型的前面或后面。

You can add a watermark for its traditional purpose: inserting a company name and logo into your model. 您可以为其传统目的添加水印：在模型中插入公司名称和徽标。

However, watermarks have creative applications, too: inserting a background image to create a unique model setting or overlaying your model with a translucent or cutout image (such as binoculars).然而，水印也有创造性的应用：插入背景图像以创建独特的模型设置，或者用半透明或剪切图像（如双筒望远镜）覆盖模型。
