About Round Placement Ambiguity
As you work with rounds, you may encounter a situation when more than one possible placement location exists for the current round set. This can happen when two surfaces intersect in multiple, distinct locations. If this situation occurs, placement ambiguity results in which the placement of the round pieces is unclear due to the selected references and part geometry.
You can address placement ambiguity using two methods. The table below illustrates the two types of placement ambiguity and the methods used to address them.
Placement Ambiguity
Ambiguity Type
Round Set Ambiguity
The round set contains round pieces that co-exist and can be placed in various locations given the selected references and part geometry. If this occurs, the round set contains ambiguity.
Method: Use the Pieces tab. From the Pieces table, select the round piece to exclude and select Excluded. All other pieces are Included by default.
1. Surface references
2. Round piece 1
3. Round piece 2
4. Round piece 1 excluded
5. Round piece 2 excluded
6. Both round pieces included
Mutually Exclusive Pieces
The round set contains ambiguity, however, the round pieces cannot co-exist. This results in mutually exclusive pieces.
Mutually exclusive pieces can be placed in different locations between the same referenced surfaces. These pieces are mutually exclusive in which only one can be selected for the round. This can occur if surfaces from two different quilts are used as references.
Method: Use the Next Solution button on the Round tab. Click the button to view each group and select the preferred group for the round.
1. Surface references
2. First round group displayed
3. After viewing groups, preferred round group is selected and the round is placed.
