<p>PURPOSE: To attain analysis, etc., by an assembly model by connecting parts on a computer so as to generate three-dimensional assembly data based on three-dimensional data of two parts and assembling information of these parts. CONSTITUTION: Assembling information is extracted by an extraction part 102 from an assembling drawing 101 provided with connection information of an endpoint node to connect the parts to prepare the data base 3 of assembling information. And, three-dimensional assembly data is prepared based on three-dimensional data of a single item generated from a 2D/3D transformation part 105 based on the two-dimensional drawing 104 of single piping. Namely, three-dimensional data of a single part described in assembling information is read and the number of a connecting destination is set to both endpoint nodes of each part to retrieve the terminal point of a connection opposite side on the parts starting side with the set number. And, a vector at the wiring terminal point of each other is calculated to calculate a rotation angle. Similar processing is made with regard to the terminal point side of parts to rotate- move all the pieces of 3D data of parts. Three-dimensional data of the assembly model is generated by repeating these processing.</p> |
