Comparing Models
The Compare tool becomes available when exactly two items are selected. These can be any types of item, but the compare tool is most useful when comparing two versions of the same model. During the comparison, JetStream will start at each item and recursively travel down each path, as seen in the standard selection tree, comparing each item it comes across in terms of the criteria requested.
When the comparison has finished, you have the option of saving the differences as Selection Sets with comments describing the differences in more detail.
Select exactly two items in the scene (see for more information on how to do this).
Go to Tools, Compare
The Compare dialog is displayed
In the Find Differences In section of the dialog, check all the boxes of the criteria that you want JetStream to compare for differences between the two items. Overridden Material and Overridden Transform relate to changing the color and/or transparency in JetStream and changing a file's origin, scale or rotation since loading into JetStream, so these are unchecked by default. All the other criteria relate to properties of items from the original CAD model.
Check Save as selection set if you want to save the selected items that you are comparing between as a selection set. You can then use this for later comparisons between the same items.
Check Save each difference as set if you want to save the resulting differences found in the comparison between the two items as a selection set for later analysis. The selection set will also have a comment attached detailing the differences in more depth.
Check Remove old results if you want to remove any selection sets resulting from a previous comparison, in order to reduce confusion when looking at the results.
Check Hide matches if you want to hide all items that turn out to be the same in the comparison, when the comparison finishes. To show them again, reset all hidden items
Check Highlight results if you want to highlight each resulting difference with a color override, when the comparison finishes. Reset the color using the reset material command.
Click OK to start the comparison, or Cancel to return to JetStream without making any comparison. At any time during the comparison, you can click on Cancel on the Exporting dialog to abort the comparison.
Comparing two items
The colors of the resulting highlights are as follows:
White for items that match;
Red for differences between items;
Yellow for things found in the first item that aren't in the second;
Cyan for things found in the second item that aren't in the first;
