To Create a Variable Round
If you are using two surfaces to create a Variable round, refer to To Create a Surface-to-Surface Variable Round.
1. In the graphics window, select the references from which to create the round. Notice that the round propagates across tangent neighbors until it encounters a break in tangency. However, if you use a One-by-One chain, the round does not propagate across tangent neighbors.
2. Click Model > Round. The Round tab opens, and preview geometry is shown. Notice that the selected references are in the References collector on the Sets tab.
3. Place your cursor over the radius anchor, right-click and choose Add radius from the shortcut menu. The system copies the radius and its value and places the radius at both ends of the round pieces.
* These are the default radii for a Variable round. These radii do not contain anchors and cannot be relocated. To delete these default radii, you must use Make Constant from the shortcut menu. This command converts the active round set from Variable to Constant.
4. To add another radius, place your cursor over the handle of the radius that you want to copy, right-click and select Add radius from the shortcut menu. These additional radii contain anchors. You can drag an anchor or snap it to a datum point reference to relocate the radius.
* You can select Delete from the shortcut menu to remove the radius.
5. To define a radius, drag the radius handle to the preferred distance or snap it to a reference. The system displays the distance value in the graphics window and dynamically updates the preview geometry.
* You can also type a new value in the distance value box or select a most recently used distance value from the list in the Radius table (Radius column) located on the Sets tab.
6. Click .
You can also use the Add radius, Delete, and Make Constant shortcut menu commands from the Radius table on the Sets tab.
You can also use Make variable from the shortcut menu to convert an existing Constant round to a Variable round.
If you are using a chain as a reference and you want to modify it, click Details on the Sets tab and use the Chain dialog box.
To quickly define a radius, double-click the distance value in the graphics window. After the box opens, type a new value and press ENTER, or select a most recently used value from the list.
You can always select Default in a most recently used list to enable the system to determine the value.
As you work in the graphics window, you can use Clear from the shortcut menu to clear all references from the active collector.
To remove a reference from within a collector, select the reference that you want to remove, and with your cursor still in the collector right-click and select Remove from the shortcut menu.
To easily create a round as you work in the graphics window, select edge references, right-click and choose Round Edges from the shortcut menu. The Round tool opens, enabling you to continue working with the round. Note that this command is available only if you select edge references.
