This study aimed to reveal the views of prospective mathematics teachers on the use of the Tinkercad program. This case study, utilizing a qualitative research method, was conducted with 18 prospective mathematics teachers currently enrolled in a fourth grade education program at a state university in a province in western Turkey. The convenience sampling method was employed to select the participants. The data obtained via the questionnaire form created by the researchers were analyzed using the content analysis technique. The results of the research indicated that the majority of prospective teachers held a positive opinion of the Tinkercad program, with the majority of them believing that it could be applied to the subjects of solids and geometric shapes. Upon examination of the opinions regarding the positive aspects of the program, it was found that the opinions were generally positive, with the program being perceived as understandable, clear, diverse, easy to use, and providing concretization. In contrast, the negative aspects of the program were not widely discussed, with the majority of prospective teachers stating that they did not perceive any negative aspects. However, a few prospective teachers expressed difficulty using the mouse or buttons. Additionally, the majority of prospective teachers perceived the program to be time-consuming. With regard to the utilization of the Tinkercad in a professional context, the majority of prospective teachers indicated that they would use the program in their future professional roles.
