1. Go to the 'Settings' panel and tap on 'Snap' to open the snap options.
  2. Snap options are:
  • Snap to Grid - sketching lines will be snapped to the grid. Also, when applying global transforms (moving, rotating and scaling).
  • Center of the Axis -- usually being used when moving objects and want them to be centered to the axis
  • Center of an Object - usually being used when you want to center an object within another object
  • Edges - when moving objects, they will be snapped to the object's bounding box edges
  • Curves Edges - when sketching or editing control points, the edges of a line will be snapped to other lines' edges
  • Any curve point - when sketching, the sketche dline will be snapped to any point on another curve
