在 Impress 和 Draw 中，您可以使用线条连接任意两个形状，我们称其为连接符。当您在形状之间绘制连接符时，连接符将会附加在每个形状的粘结点上。每个形状都有一些默认的粘结点，且默认粘结点的位置取决于特定的形状。您可以为形状添加自定义的粘结点，并将连接符附加到自定义的粘结点上。
Do one of the following to get existing gluepoints visible for all elements:
Click the Gluepoints icon on the Drawing toolbar; or
Click the Insert Gluepoint icon on the Gluepoints toolbar.
Select element on slide where you want to add gluepoints.
If the shape is filled, you can click anywhere inside the shape. If the shape is unfilled, you can click the border to insert a gluepoint. Once inserted, you can drag the gluepoint to another position inside the shape.
With the four icons next to the Insert Gluepoint icon, you choose the directions which will be permitted for a connector at this gluepoint. You can choose one or more directions for a particular gluepoint.
If the Gluepoint Relative icon is active, the gluepoint moves when you resize the object to keep its position relative to the object borders.
If the Gluepoint Relative icon is not active, the icons next to it are no longer grayed out. With these icons you can decide where a gluepoint will be placed when the size of the object is changed.
