This option allows you to create a complex blend by using a series of point to specify radii. The Part Tree must be active for all of the features of Variable blending to work. but the points must be EXACTLY on the original edge (to 8 significant digits). Use the N SEKE (near) or Near snap to ensure correct placement. Do not use the Dot or AutoCAD point options as they are infinitely small and the Variable Blend option uses the size of the point to control the size of the fillet.

  1. Use the point tool to set points along the edge that is to be filleted.
