CST2013: History Tree

Navigation Tree: Components<Component Name><Solid Name>Properties

The history tree displays the history of the creation of the current shape.

As you can see, some entries in this list have a + or a – sign in front of them. If you click on these signs the tree will expand (for a + sign) or shrink (for a – sign).

Every entry in the history tree that has such a sign attached to it marks a point where another solid gets involved into the creation process. The items appearing when the tree is expanded show the history of the involved shape.

You can use the tree to edit the different shapes and their modifications that are used to complete the final solid. However, the history itself cannot be edited here. Therefore, you must use the History List.

There are two different types of History Trees, but their structures are similar:

The first type is shown in Example 1 and represents the new Fast Model Update. This means that when you edit a certain solid, the whole history is not processed to update the changed solid. Only the affected history blocks are executed. This saves time while editing a solid or any other part of the project.

The second type is shown in Example 2 and represents the old edit system. This means that the whole history is processed to update the changed solid. The second type is activated automatically if the History List contains an entry that is not known to the Fast Model Update. After the old system is active, the Curves Tree will also be reactivated. The new edit system handles curves in the same tree like solids.

What is the difference between the tree in Example 1 and Example 2?

In Example 1 the order of the shown items is such that the step that is carried out first is listed at last. The opposite behavior is shown in Example 2 where the step that is carried out first is listed at first. Another difference is that the parts in the tree that can be edited are written bold in Example 1. These are the parts for which the edit button is activated.

Edit...

The Edit button is active only for those items that can be edited.

Pressing the edit button for one selected action leads to the same dialog box that had appeared when doing this action during the solid construction. As soon as you close this dialog box after having changed something, the update starts, depending which one of the above named History Trees is activated.

Close

Closes this dialog box without performing any further action.
