Curve Entities

SketchUp's Curve entities are a combination of multiple line segments that are connected together. These entities act as a single line in that they can define the edge of a face and also divide a face. Additionally, selecting one segment of the curve selects the entire Curve entity.

Draw curves with the Freehand Tool.

Note - You can explode a curve into regular edge segments using the Explode Curve context menu item (see the Curve Context Menu Items section later in this topic).

The following image contains a Curve entity. Curves can begin and end at the same point (as in the following image) or start and end at different points.

Note - The model in the previous image contains two entities: a Face entity (in the middle) surrounded by a Curve entity (the continuous edge).

Editing a Curve Entity

You can change the length of a Curve entity, that does not yet bound a face, by using the Move Tool. To edit a Curve entity:

1. Select the Move Tool. The cursor will change to an four-way arrow.
2. Move over the Curve entity to locate an endpoint of the Curve entity.
3. Click and hold on the endpoint of the Curve entity.
4. Move the cursor to adjust the length of the Curve entity.
