To Define a Patch Transition
This topic is a continuation of the To Define a Round Transition topic. If you did not follow the procedure in that topic, please refer to it under Related Links.
1. To add a fillet to a Patch transition, click the Optional surface collector located on the Round tab or on the Transitions tab to activate the collector and select a surface for the Patch transition. The system does the following:
Adds a fillet to the Patch transition and displays the fillet radius in the graphics window and in the Radius box on the Round tab. This fillet becomes the fourth side of the resulting patch and is tangent.
Populates the Optional surface collector on the Transitions tab with the reference information. Notice that the corresponding Round tab collector indicates that an item has been selected.
2. To define the fillet radius, drag the radius handle, or type or select a new radius value in the Radius box on the Round tab. The preview geometry is dynamically updated.
3. If you want to cap the gaps between the active transition and part geometry by creating end surfaces, select the Capped check box located on the Round tab. Notice that this check box is available only if you use the Surface or New quilt attachment type (see About Round Attachment Types). This check box is cleared by default.
Side surfaces must exist in order to extend and use them as capping surfaces. If not, the round piece cannot be capped.
This check box caps only the gaps of the active transition while the Create end surfaces check box located on the Options tab caps all round piece ends for the entire round feature. Remember, the Round tab check box overrides the Options tab check box. This enables you to cap the gaps of the active transition even if you decide not to cap all of the round piece ends for the round feature.
You cannot cap rounds between a solid surface and a quilt surface.
4. At this point, the transition is defined. Do one of the following:
Define another transition.
Click to return to Set mode and continue working with round sets.
* You can also use Back to sets from the shortcut menu.
Click to save your changes, create the round, and close the Round tool.
* To restore the default transition, select Default from the Transition Type box on the Round tab, or from the shortcut menu. The system does not display default transition types on the Transitions list.
Do not use Delete transition from the shortcut menu or use the DEL key to remove a transition type from the Transitions list. If you do use it, you can do one of the following to restore the default transition type: Press CTRL+Z to undo the selection, switch to Set mode, or close the Round tool.
You can also use Patch Optional Surface from the shortcut menu to activate the Optional surface collectors.
You can also use Capped from the shortcut menu to cap the gaps of the active transition.
To preview various transitions before selecting one, place your cursor over each transition type in the Transition Type box. The corresponding transition geometry is highlighted in the graphics window.
To quickly change a value as you work in the graphics window, double-click the existing value. 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.
You can always select Default from the Transition Type box, or from the shortcut menu enabling the system to determine the transition type for the round. Notice that the transition type is in parentheses.
To remove a reference from within a collector, select the reference that you want to remove, and with your cursor in the collector, right-click and select Remove from the shortcut menu.
