<p>When it is attempted to define a profile that consists of a combination of a first profile (1) and a second profil (2) which have been defined already, it is determined if the first profile (1) and the second profile (2) have an intersection or not based upon the designation of the first profile (1) and the second profile (2). When they do not have an intersection, error is displayed to represent that the combination profile is not possible. When they have an intersection, it is determined whether at least either one of the first profile (1) and the second profile (2) is open. When none of them is open, closed profiles consisting of the combination of the first profile (1) and the second profile (2) are successively drawn so as to be discriminated from other profiles. A desired closed profile is selected when it is just drawn and, thus, the combination profile is defined.</p> |
