# 2.1.1 Circle Track

A circle track is a special form of a curved track that extends 360° and has no endpoints. The drop down menu, which allows selection of the Circle Track creation method, is invoked from the down arrow button located on the right side the Circle track button.

The three methods (with their Icons and Shortcut keys) used to create a Circle Track are:

  (Section 2.1.1.1) `Control+8` - Use the Fixed Radius specified on the Circle Radius control displayed on the Status Bar (Section 3.1). `Left-Drag` the Circle track into position.

  (Section 2.1.1.2) `Control+9` - `Left-Drag` from tangent point (Edge) of the Circle track to the Center.

  (Section 2.1.1.3) `Control+0` - `Left-Drag` from the Center of the Circle track to the edge.

If Snap Grid (Section 2.12.2) is enabled then circle centers will be constrained to the grid.

Circle tracks are useful for fitting curves into corners and other tight places. They're also handy when establishing an initial layout and finding out "what will fit".

You can join to and from circles, after which they become curved tracks.
