      Exercise - working with mesh File
      9.3 MB application/octet-stream

      The exercise focuses on working with a mesh (STL data) that has a number of errors. The mesh was created by optical 3D digitization of a hand-made sculpture. The goal is to modify the data so that it can be used for 3D printing.

      CAD models Assignment
      Opened: Friday, 13 October 2023, 12:00 AM
      Due: Friday, 3 November 2023, 9:10 AM

      Prepare a CAD model in STL format of approx. 50x50x30 mm of a part suitable for additive manufacturing and submit it to the teacher for inspection and possible further discussion on Friday 2023/11/03. It is possible to prepare also an assembly of several parts into one functional unit as a work of more students. You can upload the file(s) here but it is not necessary.
