Creating rounded corners

 

Use the Create Rounded CornerClosed tool to trim back or connect two intersecting lines or arcs so that they meet with an arc tangent at both ends. You can also use this tool with coplanar 3D lines, such as lines you created by blending.

The sketch grid must be visible in the workspace before you can create rounded corners, which are also known as fillets.

 

To connect two lines with a rounded corner

  1. Click Create Rounded Corner from the Sketch group on the DesignClosed tab.

  2. Select a line or arc.

    The first line or arc you select will be extended, if necessary.

  3. Mouse over another line to preview the round that will be created.

    If you mouse over a line that is the edge of a solid, that edge will not change. Only a sketched line will change. The radius of the arc is previewed as you move the mouse. Enter a radius to dimension it.

  4. Select an intersecting line to trim the lines, or a non-intersecting line to connect the lines.

    Where you click on the intersecting line defines the radius of the tangent arc, or you can dimension the round (or chamfer) by entering its diameter.

    If the lines intersect, click the part of the intersecting line you want to keep. If the lines do not intersect, you can click anywhere on the line to extend the first line to form a rounded corner. Circles are never trimmed.

For lines that meet at a corner, you can select and drag the vertex.

You can also enter the tool first and then make your selection.

To create multiple rounded corners using Ctrl

  1. Sketch some curves with several vertices (e.g. a rectangle).
  2. Enter the Create Rounded Corner tool.
  3. Click a corner vertex and drag to preview the round.

  4. Press and hold the Ctrl key

  5. While holding Ctrl, click and drag another corner vertex to preview BOTH rounds.

  6. Press and hold the Ctrl key
  7. Repeat for the remaining corners.
  8. On the last corner (meaning no more Ctrl key selection), you will see all rounds previewing simultaneously.
  9. Click to place the rounds or enter a radius value

To edit a rounded corner

Drag the rounded corner with the Select tool to change its radius. Tangency is maintained.
