Many tools used to design drills work with existing shapes. In order to use these tools that modify existing shapes, one must select the performers that will be edited. That process is called “selection” and is accomplished using Selection tools. This section covers using all Selection tools: the Pointer tool, the Box Selection tool, the Lasso tool, the Spotlight Selection tool, and the Profile Selection tool.
You’ll find that while designing it is often quite useful to cut or split a shape into smaller shapes, or combine two or more shapes into larger shapes. For example, imagine an arc splitting into thirds and each third floating into one of three lines. To make the editing easier, we would first want to split the arc into three parts. That can be done using the Knife tool. After cutting the arc, we can select one part of the arc independently of the others. We would then select the first part of the arc and morph it into a line, and repeat the process for the remaining parts. The process of splitting and combining performers is called “regrouping” and is done using the Regrouping tools. This section covers using the Regrouping tools: the Knife and Glue tool.
