Polyline / Radius / Trim / <Select first object>: Use an object selection method or enter an option
The FILLET command rounds the edges of two arcs, circles, elliptical arcs, lines, polylines, rays, splines, or xlines with an arc of a specified radius. FILLET also rounds the edges of solids.
If the TRIMMODE system variable is set to 1, FILLET trims the intersecting lines to the endpoints of the fillet arc. If the selected lines do not intersect, AutoCAD LT extends them so that they do.
If both objects are on the same layer, AutoCAD LT creates the fillet on that layer. Otherwise, AutoCAD LT creates the fillet line on the current layer. The same applies to fillet color and linetype.
You cannot fillet line segments that intersect outside the drawing limits when limits checking is on.
Inserts fillet arcs at each vertex of a 2D polyline where two line segments meet.
Select 2D polyline: Use an object selection method
If one arc segment separates two line segments that converge as they approach the arc segment, the arc segment is removed and replaced by a fillet arc.
Note: You cannot fillet polyline segments from different polylines.
Defines the radius of the fillet arc.
Enter fillet radius <current>: Specify a distance or press ENTER
The value you enter becomes the current radius for subsequent FILLET commands. Changing this value does not affect existing fillet arcs.
Controls whether AutoCAD LT trims the selected edges to the fillet arc endpoints.
Trim / No Trim <current>: Enter an option or press ENTER
Trims the selected edges to the fillet arc endpoints.
Does not trim the selected edges.
Selects the first of two objects required to define a 2D fillet.
Select second object: Use an object selection method
If you select lines or arcs, AutoCAD LT extends then until they intersect, or trims them at the intersection.
If the selected objects are straight line segments of a 2D polyline, they must be adjacent or separated by only one other segment. If they are separated, FILLET deletes the segment that separates them and replaces it with an arc.
More than one fillet can exist between arcs and circles. AutoCAD LT chooses the fillet with endpoints closest to the object selection points
Circles are not trimmed; the fillet arc meets the circle smoothly.
You can fillet two lines with different extrusion directions only if the Z values of the endpoints of both lines are equal in the current UCS.
