Applying Fillets
Use the Fillet command to create rounded corners by replacing parts of two Lines with an Arc. The filleted entities do not have to intersect, and they can overlap. If the entities overlap, they are trimmed to create the rounded corner and the Lines to be filleted are connected to the fillet Arc.
A fillet radius of 0 creates acute instead of rounded corners. Press Shift while selecting entities to override the current fillet radius with a value of 0.
To apply fillets:
- Click Modify > Fillet (or type Fillet).
- In the graphics area, select the first entity whose intersection is to be filleted, or specify an option:
- Multiple: Lets you apply fillets to multiple entities. By default, you complete a single fillet. You are prompted repeatedly to select a first and a second entity to fillet until you press Enter. You can then change the fillet radius or toggle the trim mode between fillet operations.
- Polyline: Lets you fillet PolyLines treated as a single entity. The command fillets all vertices of a PolyLine or Polygon in one step and inserts fillet Arcs at each vertex of the PolyLine where two Lines meet, if applicable. The Polyline option prompts for a 2D PolyLine, then reports the number of Lines processed and the number of Lines too short to be filleted.
- Radius: Defines the radius for the fillet Arc. Changing the radius does not affect previously created fillet Arcs.
- Trim mode: Indicates whether to erase the Line segments that lie beyond the fillet Arc.
- Undo: Reverses the previous fillet, only if Multiple mode is active.
- Select the second entity.
- - or -
- Press Shift and select an entity to apply a corner to. The selected entities are lengthened or shortened to intersect without a filleting Arc. This method creates acute corners without changing the fillet radius.
