  • Propagate function copies the form to multiple frames and displays a dialog box where you can specify the number of copies or the frame to which you want to copy the object. The keyboard shortcut is Ctrl + B. On how to propagate only filtered shapes, see Shapes converter
    There are two options available:

    • Propagate forward (Fw propagate) creates a copy of the object on N subsequent frames at the same position.
    • Propagate backward (Back propagate) creates a copy of the object on N previous frames at the same position.

Labels

In this tab, you can lock or hide objects of a certain label. To change the color for a specific label, you need to go to the task page and select the color by clicking the edit button, this way you will change the label color for all jobs in the task.

Example of “Labels” tab

Fast label change

You can change the label of an object using hotkeys. In order to do it, you need to assign a number (from 0 to 9) to labels. By default numbers 1,2…0 are assigned to the first ten labels. To assign a number, click on the button placed at the right of a label name on the sidebar.

Example of shortcuts for fast label change

After that, you will be able to assign a corresponding label to an object by hovering your mouse cursor over it and pressing Ctrl + Num(0..9).

In case you do not point the cursor to the object, pressing Ctrl + Num(0..9) will set a chosen label as default, so that the next object you create (use the N key) will automatically have this label assigned.
