Abstract

Cilj ovoga rada je identificirati metode koje pružaju mogućnost automatskog prepoznavanja postojećih veza između komponenata sklopa iz CAD modela. CAD alat korišten tijekom ovoga rada je Siemens NX. Neke od metoda su direktno bazirane na geometrijskim relacijama kreiranim prilikom konstruiranja, a ostale se koriste drugim dostupnim CAD podacima kojima se pristupa pomoću API-a. Sve identificirane metode su detaljno objašnjene kroz rad, a prepoznavanje veza je bitno za podršku sljedivosti. Razvijen je odgovarajući algoritam za svaku od identificiranih metoda koja se pokazala kao pouzdana za detekciju veza između dvije ili više komponenata. Razvijeni algoritmi su zatim pretočeni u Java programski kod koristeći Eclipse razvojno sučelje. NX Open API je korišten za komunikaciju sa Siemens NX-om kako bi se pristupilo raspoloživim CAD podacima. Prikupljeni podaci su analizirani i preoblikovani u razumljiv format koji predstavlja vezu između komponenata.

Na temelju kreiranih veza iz CAD modela, kreirana je DSM matrica. DSM matrice imaju svojstvo pružanja jedinstvenog pogleda na arhitekturu sustava i kao takve su pogodne za vizualizaciju rezultata u ovome radu. Dodatno, metode za manipuliranje podataka koje su razvijene posebno za DSM matrice pružaju dodatne mogućnosti pri analizi sustava. Svaka od tih metoda ima specifičan cilj pa su stoga detaljnije objašnjene one koje su od posebnog značaja za podatke korištene u ovome radu. Za potrebe testiranja razvijenog programa kreiran je CAD model na temelju kojega je nastala DSM matrica. Kreirana DSM matrica predstavlja rezultate algoritma koji sadrži sve identificirane metode za izvlačenje relevantnih veza. Rezultati su zatim uspoređeni s DSM matricom koja je nastala ručnim bilježenjem veza i koja služi kao pravovaljana referenca.

Abstract (english)

The main goal of this master thesis is to explore available methods for extracting component relations from the CAD model in order to support traceability. Siemens NX is used as a CAD tool because Daimler recently decided it will use that platform in the future product development process. At the time of writing this thesis, they are still in transition from CATIA. Some of the methods are based on Siemens NX features that are used while designing the product and others are developed based on new ideas that use information provided by the software API. The methods found are described in detail through the thesis.

A proper algorithm is developed for each individual method that has been identified as valid for extracting relations between two or more components. Developed algorithms are then put into proof of concept using Java in Eclipse IDE which uses NX Open API to communicate with the available Siemens NX CAD data. Collected data is used to extract relations. Based on relations extracted from the CAD model, the DSM matrix is created. DSM matrices have the possibility to support traceability providing an additional way of looking at the system architecture and therefore are chosen as a tool in this thesis. Also, DSM post- processing methods enable an additional manipulation of data to get a better overview of the system architecture. Each post-processing method has certain goals and therefore the majority of them that are important for this thesis are explained in detail. The final DSM is created based on the CAD model created for the purposes of this master thesis. Results are discussed and compared with a manually created DSM which is considered as a valid reference.
