The option is provided for editing the list of the original elements of the copy (array). In this mode, you
can add the new elements to the list of the objects to be copied and delete some of the elements from the list
of selected.
The option is accessible for copies created by the commands “XM: Create Copy”, “XT: Copy and
Rotate”, “XA: Copy and Scale”. It allows clipping the image of the copy by a hatch. To do this, upon
calling the option, select the desired hatch by clicking .
If the clipping hatch is used for this purpose only, we recommend setting its
flag “Invisible”. The diagram shows a copy image before and after selecting
an invisible hatch for clipping. In addition to the described capabilities, the
attachment points can be redefined for the selected copy (array).
To do this, select one of the transformation vector ends or an attachment point by clicking it (in the cases
of scaling, rotating and the circular array). After that, specify the new attachment point(s). At this moment,
the following options will be available in the automenu:
Create Node at point
Select Node
After defining the new attachment point, the element being edited will be drawn according to the applied
changes.
The commands for editing a copy or an array, or their elements, are
also accessible via the context menu. Simply select one of the
elements of a copy/array and right click . In the coming up
context menu, the editing commands will be provided for the
selected element, as well as for the whole copy or the array.
You can change the properties of the selected element of a
copy/array (the default properties are copied from the parent
element). You can also delete the selected element of a copy/array
(without deleting the copy itself). In this case, the copy/array itself
maintains the information about the deleted element, so that it can
be restored in the future.
The editing commands for the copy/array itself are grouped in the
context menu into a submenu, named according to the copy type (such as, “Move Copy”, as shown on the
diagram). An additional command is provided among the copy/array editing commands, “Restore deleted
elements”, specifically for restoring all deleted elements of the copy.
Particulars of handling variable arrays
When modifying the number of copies in a linear or circular array, adding or deleting copies occurs in the
position immediately before the last copy in the array. This feature helps, for instance, keeping the
dimensions between the outer elements of the array throughout modifications to the number of copies in the
array. The dimensions set on “inner” copies of the array may disappear as the total number of copies is
reduced. The same is true for any 2D constructions: the elements attached to the outer copies of an array will
always maintain the correct position, regardless of the changes to the array.
