Abstract [en]

In order to create a complete BIM-model of a whole project, it is common thatseveral programs and software-suites are used. It is beneficial if the models producedin these programs are compatible with each other, in order to improve theeffectiveness of the construction process as a whole. If a model created in oneprogram has to be altered in order to be compatible with another the result is excesswork.Designers, utilizing Civil 3D, more often than not have to alter constructions whichare to be part of a surface-model. This creates a situation where the construction hasto be modelled twice as Civil 3D cannot use the original model. The purpose of thisessay is to research the problems pertaining to surface creation in Civil 3D and theconsequences they have for designers.To better understand the process of surface creation of an object containing verticalparts a practical study of the subject has been carried out in Civil 3D. A simpleconstruction was created in Revit and imported to Civil 3D as to create a surface ofthe highest parts of the construction.The methods used by designers working in Civil 3D were researched as a qualitativestudy by means of surveys and interviews. The result of the study makes it clear thatthe respondents are dependent on models from different fields involved in the sameproject. As the models do not automatically adapt to the software used by thedesigners in question a considerable amount of manual reconstruction of models areneeded. Fundamentally, the issue is two-fold. Firstly, designers depend upon 3Dmodels and objects created by others. Secondly, Civil 3D cannot render verticalsurfaces or overhangs while creating surfaces. Knowledge about the way Civil 3Dworks and utilizing methods avoiding future problems before they occur has thepotential to improve workflow. Sufficient communication between parties involvedalso results in a more effective process.
