FILLET & TRIM draws an arc entity at the intersection of lines, circles, arcs, ellipses and splines for a smoothly rounded corner. This command will trim or extend the selected lines or arcs to meet the ends of the fillet arc. If you want to add a fillet but do not want to change the selected entities in any way, use the FILLET ONLY command instead.

Note: do not specify fillets of zero radius. A zero-radius fillet can not exist. Use TRIM TO INTERSECTION (image\TRIMINT.gif) instead.

  1. The prompt reads "1st entity:". Use the pick cursor and select an entity. CC3 displays the selected entity in gray.

  2. The prompt reads "2nd entity:". Use the pick cursor and select an entity (it must be neither parallel nor concentric to the first entity). CC3 displays the selected entity in gray.

  3. The prompt reads "Fillet radius [n]:". To specify a radius, right-click to accept the default or prior value, or type a new value and press ENTER.

CC3 draws the fillet arc and automatically trims or extends the selected entities to meet the ends of the fillet arc.

Fillet entities

·   That cross,

·   That are already connected at their endpoints,

·   That don't meet (as long as they aren't parallel or concentric).

When filleting the intersection of a line and a circle (or arc)

·   Fillets can lie inside or outside the circle, and above or below the line.

·   Select the entities on the sides where you want the fillet.

·   CC3 will trim/extend arcs, but not circles.

If you fillet the intersection of two arcs or circles

·   CC3 can only draw external fillets - outside the curves of the existing entities.

·   CC3 will trim/extend arcs, but not circles.
