Rounding the inside and outside corner of two surfaces.

Pulling edges on geometry that automatically determines rounds will be variable radius.

When creating surface-to-surface rounds, the expansion direction depends on the order in which you select the edges. In the example above, the rounds expand toward the left because the upper edge was selected first.

Rounding the edge created by two rounds with one edge not tangent.

Pulling rounds in a tangent chain. Pulling the selected tangent chain does not change the round shown in blue.

Adding and changing a rounded edge on a shelled or offset part changes the inside faces.

Rounding elliptical edges.

 

Creating a full round by selecting three faces

1. Click the Pull tool.

2. Check the Edit as Variable Radius Round option.

• Click the Pull arrow on an end of the round face and drag toward or away from the face to adjust the radius at the edge of the round.

• Click the Pull arrow pointing toward the center of the face and drag it along the face (or enter a length or percent) to set another point where you can adjust the round's radius.

• Hold Ctrl and drag to copy a control point.

• Press Tab to switch among and edit the dimensions by typing a number.

• Two rounds that intersect at a shared edge can be made variable together by selecting the shared sharp edge for modification. Both rounds become variable at that point. They can be made variable independently by selecting the sharp end edge that is not shared by the rounds.

In the Pull tool, when you select an edge of a constant radius round, the Smooth option becomes enabled if the geometry allows it. When checked, the transition between radius at each end of the round will vary smoothly instead of linearly. Once set, the Smooth option remains set for subsequent rounds until you change it.

 

The image below shows a Smooth variable radius round. Other editing examples follow.

 

 

 

Examples

Editing a variable radius round

 

 

The variable radius round handles have a drag (ball) handle. The center Radius Handle cannot be dragged; all radii values are adjusted at once.

Click the ball and drag to add and place a new radius handle.

To remove a rounded edge with the Pull tool

This method completely removes the rounded edge.

1. Click the Pull tool.

2. Select the rounded edge.

3. Select the Round option in the Options panel or from the mini-toolbar.

   The round is removed.

To remove a rounded edge with the Fill tool

This method removes the rounded edge and creates a round group in the GroupsSets of objects that appear in the Groups tab. You create a group from any set of selected objects. Information such as Selection, Alt+selection, move anchoring, axis, and ruler dimension is all stored with the group. panel. You can right-click the group and select Reattach Round to restore the rounded edge.

1. Click the FillUse the Fill tool to simplify or clean up geometry by extending surrounding faces to eliminate a selection. The selected region is filled in or healed with the surrounding surface or solid. tool in the Edit group on the Design tab.

2. Select the rounded edge.

3. Click the Complete tool guide.

   The round is removed and a round group is created.
