Abstract

CAD (eng. Computer Aided Design) i BIM (eng. Building Information Modeling) dva su ključna i različita pristupa pri izradi računalnih modela pri konstruiranju i projektiranju. CAD pruža detaljne vizualizacije dijelova i sklopova, dok BIM integrira dodatne projektne informacije. Sve veće korištenje BIM-a u građevinskim projektima, radi svojih bogatih informacija, prisiljava prilagodbu od strane CAD korisnika.
Postoji nekoliko načina interoperabilnosti i prijenosa CAD modela u BIM model. Način koji se pri tome koristi uvelike ovisi o važnosti pojedinih komponenti u daljnjem odvijanju projekta. Prilikom tog prijenosa kod konfiguracijskih modela, jedino se prenosi aktivna konfiguracija. Ova činjenica prisiljava korisnike na pristup izrade dva identična modela, jednog u CAD-u, drugog u BIM-u.
U okviru ovog rada izrađena su dva konfiguracijska modela, jedan u računalnom CAD alatu Onshapeu i drugi u računalnom BIM alatu Revitu. Primjerom modela konfiguracijske kupaonice prikazano je kako se radi o dva u potpunosti različita postupka. Postupak izrade konfiguracijskog modela u CAD-u nikako nije prenosiv na postupak izrade konfiguracijskog modela u Revitu, radi potrebe za definiranja elemenata u obitelji i stroge hijerarhije između njih. Same konfiguracije pružaju više opcija i fleksibilnost u Onshapeu, nego u Revitu značajka Design Options.
Svaki od modela komplementaran je te ima svoje prednosti i mane. U pogledu proizvodnje i brzine izrade modela svakako je CAD model bolja varijanta od BIM modela. Što se tiče implementiranja modela u projekte, radi velikog broja informacija o komponentama ipak je bolji BIM pristup.

Abstract (english)

CAD (eng. Computer Aided Design) and BIM (eng. Building Information Modeling) are two key and distinct approaches in computer modeling for construction and design. CAD provides detailed visualization of parts and assemblies, while BIM integrates additional project information. The increasing use of BIM in construction projects, due to its rich information, necessitataes adaptation for CAD users.
There are several ways of interoperability and transferiing CAD models into BIM models. The method used largely depends on the importance of individual components in the futher progress of the project. During this transfer in configuration models, only the active configuration is transferred. This fact forces users to approach creating two identical models, one in CAD and the other in BIM.
Within the scope of this study, two configuration models were created, one in the computer CAD toll Onshape and the other in the computer BIM toll Revit. This example of a bathroom configuration model illustrates how there are two entirely different procedures. The process of creating a configuration model in CAD is not transferable to the process of creating a configuration model in Revi, due to the need to define element sin families and the strict hierarchy between them. Configurations themselves offer more options and flexibility in Onshape than in Revit's Design Options feature.
Each model is complementary and has its own advantages and disadvantages. In terms of production and speed of model cration, the CAD model is certainly a better option than the BIM model. However, when it comes to implementing models into projects, due to the large amount of information and components, the BIM approach is better.
