Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION
  IN CATIA
  .
  Restriction Explanation
  During a sketch creation operation, there
  are actually 2 commands :
  - 1 - launch sketcher creation command (we
  create the sketch by clicking on Sketcher
  icon or on Sketch with absolute axis
  definition icon)
  .
  - 2 - launch sketcher edition command (this
  operation launch the sketcher workbench by
  selecting plane support or when defining
  the references of sketch).
  .
  But the Undo code handles commands
  independently : in case operations of one
  user are stored as 2 commands, 2 undo
  are necessary.
  There exist no relation between one
  command and another.
  This is a basis specification of the undo
  function and whole undo code cannot be
  changed for one and only specific case, the
  sketch creation. Thus it is a permanent
  restriction.
  .
  We understand that it is unusual
  for user,  to obtain an empty sketch in tree
  by using undo command, although today it
  is not possible in a direct scenario to create
  a sketch in tree with no geometry in it.
  But no solution exist to solve this problem.
  .
  Remarks :
  - an empty sketch should not be a problem
  for user who can click a second time on
  undo or enter and exit sketch to make it
  disappear.
  - moreover to create empty sketch is being
  discussed at sketcher development team ;
  it could be implemented in a future
  release. In this case, to have empty sketch
  by performing undo would no longer be a
  problem.
