The image created by the and options may need modifications or additions, for example, add chamfers, rounds, clipping line, or place dimensions). One shall keep in mind that these options create graphics based on the "Copy with translation" functionality, therefore, it is subject to all rules and limitations imposed on direct use of this command. Thus, only graphic lines, hatches, 2D fragments and projections are copied. The snapping nodes of the copied lines can't be modified. The copied elements can only be deleted, hidden by the command "Hide/Show Elements", or their parameters modified (for example, lower the level). Besides, these can be used for snapping the construction lines (see the chapter "Lines") for new element creation. Therefore, if editing a view involves modifying existing graphic lines, two ways of handling are possible:
1. Break association of the copies with the original elements using the command "Explode Copy" of the context menu. As associations are broken, free nodes are created, thus turning the graphics on the view into a sketch suitable for modifications. One should keep in mind that further modifications of the original elements of the drawing will not propagate on the drawing view graphics, thus breaking its parametric behavior.
2. Create new graphic lines based on the copies. To do this, first create construction entities snapped to the copy entities. Then, hide the entities of the copy if necessary. Instead of the hidden lines, create new ones by snapping to the newly created construction entities.
