# Sketcher The Sketcher lets you create new shapes and work on existing shapes. See the [Sketching](/firststage/crafting/sketching.md) topic for details but here we will just note that the basic operation is to click on a sequence of points in the scene to form a path: a closed path will create a new shape; a path across the face of an existing shape will cut the face. ## Radial Menu * Undo & Redo. Note that Undo on the Sketcher will unwind a half-formed path before undoing anything else. If you change tool before completing a path, the path will be discarded. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
