Query Compare
The Qompare dialog (short for Query Compare) is used to compare the features loaded in two queries. The Qompare dialog is accessed through the Document menu.
Open Qompare
To use the Qompare function:
Select a Query label from the Query 1 dropdown (this example uses the query "Arm Six").
Select the query you want to compare the first one to from the Query 2 dropdown (this example uses the query "Legoman - Upper ^ BH").
Click the Compare button.
Your results will appear in the window as shown in the image below.
When you are through comparing your queries, click the Done button to return to your CM4D document.
Reason
Each feature row has a Reason listed in the center column to explain why CM4D determined the two features were a valid match. The Reasons are listed in the order in which CM4D checks to see if the features qualify for comparison.
Label - the two Features have Feature Labels that are an exact match
XYZ - the two Features have identical XYZ nominal measurements
Mirror - the two Features are an exact match except for the Y nominal value, of which one is the negative value of the other (and so is a Mirror point)
Alias - the two Features have the same Alias (Alias1) value. This only compares Alias, not Alias2, Alias 3 or Alias 4.
Unmatched - the two Features are not a match in any of the previous four categories, so CM4D has determined they are Unmatched. If a feature does not match any features in the other query, empty cells will appear on the opposite side of the row.
Color Codes
Reasons are also indicated by a highlight color applied to the Feature label.
Green |
Features match by Label |
Blue |
Features match by XYZ nominal values, or one feature is a Mirror of the other |
Olive |
Alias1 for both Features match |
Red |
Features do not match |
