# Point and Selection Vocabulary

Below is a list of terms that are associated with the world of ‘click and drag’ and with the pattern pieces within Garment Designer. If you have used Adobe Illustrator or other CAD type programs you will see the similarities in how Designer's click and drag functions work.

Points - These are small squares that appear at the beginning and end of a segment within the garment. They can be made ‘viewable’ by clicking within the garment or by clicking on a segment. They are made 'active' through a selection process. You can either click directly on a point, or use a drag + select action which frames the area around a point(s). In both cases, the points are selected and therefore 'active'. There are two types of points:

Hollow Points – These are viewable but not active. These appear as 'hollow' squares.

Solid Points – These are selected, and therefore 'active' points. These appear as solid red squares.

Segments - A segment can be either a straight line or a curved line. Each segment has end points as indicated by the small squares. Curve segments have additional curve control arms and points (as indicated by the circular points).

Straight Segments - These are straight lines between two end points. If you click and hold on a line, you can move it in its entirety, by dragging it to a new position.

Curve Segments - The curves used in Garment Designer are Bezier curves. These allow the user great control over the shape and arc of a curve through the use of curve control arms and curve control points.

Curve Control Arms - These are arms that extend from either end of a curved segment. One end of the arm attaches to the endpoint of a segment on the garment. The other end of the arm attaches to a curve control point.

Curve Control Points – These are round points attached to the curve control arm that extend from each end of a curve segment. You can click, hold and drag curve control points to adjust the arc of a curve. There are two actions that control the curve. Adjusting the length of the control arm changes the depth or shallowness of a curve. Moving the curve control point (and thus changing the angle of the curve control arm) changes the arc of the curve.

What is a Bezier Curve? - This is a type of curve that allows the user control over its arc through the use of control points and control arms. When you select a curve, the Bezier control arms will display. You can click and drag on the circular points at the end of the control arms to reshape your curve.
