To sketch tangent arcs:

  1. Click Tangent Arc art\ARCTANG.gif.

SolidWorks infers from the pointer motion whether you want a tangent or normal arc. There are four intent zones, with eight possible results as shown. Moving the pointer in a tangent direction creates a tangent arc. Moving the pointer in a normal direction creates a normal arc. You can toggle between tangent and normal arcs by returning to the end point and moving away in a new direction.

  1. Click .

You can transition from sketching a line to sketching a tangent arc without selecting the Tangent Arc tool by autotransitioning.

To sketch 3 point arcs:

  1. Click 3 Point Arc art\ARC-3PT.gif.

  2. Click to set a start point.

  3. Drag to set an end point.
