The thesis work is done in collaboration with Prodtex AB, which works to develop digital tools to facilitate the constructor´s work in virtual environments, for instance CAFD within CATIA V5. What the client wanted the project participants to perform was a comparison of the company's semi-automatic software for fixture design, and the traditional construction method with CATIA. The reason for the method comparison is because Prodtex AB requires data, which they can present to potential customers. The participants produced a method to enable the necessary components of the project, the method consisted of training in fixture design, fixture construction and work with the consulting company´s application. These elements have been essential for the comparison to be reliable. The main part of the assignment consisted of constructing units for the given fixture. The reason behind this is due to the necessity of a certain level of experience in fixture design, which is required to be able to assemble units with an accurate and efficient procedure. The method comparison generated data in terms of time in the measurement areas, input, design and export that the project participants analyzed and compiled in the result section. Based on the statistics, participants were able to find answers about which features the software made the most time savings of, and how abundant these were in relation to the traditional design method. A conclusion about when it was beneficial for a company to invest in the software was based on reasoning deduced from the outcome discussion.
