# 2.3.6.5 Draw PolyLine

Before the polygon is started the line width and color can be set. The Polyline Line Width field is a scaled dimension in inches if >0. If 0 it is a 1 pixel wide line at all zooms. If the value is negative, it is a scale-independent number of pixels wide.

PolyLines are created by either a series for `Left-Click`s or `Left+Drag`s, and a new "node" is placed for each. When using `left-drag`, the node will be positioned when you release the button.

  If MagneticSnap (Section 2.12.1) is enabled, An anchor point will be shown on nearby draw objects that the next point will be snapped to unless `Alt` is held.
  If it is disabled, the snap will only occur if Alt is held.
  If `Ctrl` is held down when a new point is placed, it will snap the relative angle of the new side to a multiple of 90 degrees from the previous side. On the first polyline segemnt this will be at a multiple of 90 degrees to the axes. The line from the previous point will be highlighted in Blue.
  A special blue square anchor will show when the cursor is in a position such that it is 90 degrees away from both the last point and the first point of the Polyline.
  The last drawn polyline segment dimensions can be altered using the text boxes that appear showing the segment length and the relative angle to the previous segment.
  The polyline is ended using `Enter` or `Space`.
  While drawing the Polyline certain short cuts are available by keystroke and via the Context Menu:
  `'p'` - to cover to a Polygon
  `'s'` - to smooth the last selected point
  `'r'` - to make the last selected point round
  `'v'` - to make the last selected point sharp (a vertex)
  `'o'` - to change to Section 2.3.8 mode
