To Modify an Analytic Surface Feature
1. Select a surface to modify.
2. Click > 
Modify Analytic. The Modify Analytic Surface tab opens.
Modify Analytic. The Modify Analytic Surface tab opens.3. Type a new value for the Radius or Angle or use the drag handle to change the value. For a torus you can modify both radii.
4. To set additional attachment and propagation options, right-click and use the shortcut menu or use the Attachment and Options tabs.
 | When the Attach modified geometry check box is not selected, the resulting geometry is a quilt. The appearance of the original solid surfaces is propagated to both sides of the resulting quilt. |
5. To maintain tangency between the modified geometry and neighboring geometry:
a. Click 
.
.| | If the flex_tan_propagation_default configuration option is set to on, tangency is automatically propagated. |
b. If needed, set conditions for neighboring geometric entities using the Conditions tab, the Add condition option, or the shortcut menu.
6. To navigate through other possible solutions for geometry configurations, on the Attachment tab, click Next or Previous.
| | • When you click Next, the system might stop responding while it tries to find the best possible solution. This is because it checks for all possible combinations for the solution. The system might also stop responding if a solution does not exist. At this point, to interrupt the check and continue working: 1. While the model is regenerating, click  Stop at the bottom of the window to interrupt the regeneration. A failed feature is created.2. In the Model Tree, click the failed feature and select  Edit Definition. Even if you do not make any changes in the settings, this gives you the opportunity to check if the result is what you want.3. Click  OK. The feature regenerates.• When the system is unable to find more than one solution, the Previous and Next options are not available. |
You can select a different solution when you redefine the Modify Analytic feature.
7. Click OK or middle-click to accept the feature.
