PROJEKTERING MED TVÅDIMENSIONELLA ELLER TREDIMENSIONELLA RITNINGAR : En jämförelse baserad på konsulters erfarenhet

Sammanfattning: More and more companies within the building sector are using BIM (Building Information Model). This degree project has the increased use of BIM as a background, but the work is mainly focused on possibilities and limitations specifically for the work with 3D (three-dimensional drawings). The purpose of this study is to compare the work and costs in practice when working with drawings in 2D or 3D. In addition to a literature study, drawings from a particular building are compared, where the original 2D drawings are converted into 3D. Investigations using interviews and questionnaires have been made including several different companies where the respondents have different professions. The answers were really useful, and the results are mainly based on these answers. Conducting all investigations and compiling all the answers gave a balanced picture mainly regarding the work with 3D in practice. One important result is that one should distinguish between BIM and 3D, where BIM is equivalent to a work approach that is recommended primarily for larger projects where you have the possibility to save large sums of money. The advantages and disadvantages between 2D and 3D drawings depends on how you are as a person and how much experience you have with the different software. Moreover, there is no exact figure that explains the economic gain or loss specifically by using 2D or 3D. Results and experiences of this work, however, suggests that in the fairly near future only 3D will be used.
