Tiivistelmä
Tekla Structures uses TrimBim file format for transferring serialized data. This file format is optimized for the 3D model data. However, the same file format is used for 2D drawings, and, while the format functions sufficiently with the drawings, the 2D drawing optimized file format would increase the efficiency.
The aim of this thesis is to create an enabler for the possible development of 2D engineering drawing file format. The enabler is a FlatBuffers schema, which the binary data serialization with FlatBuffers can be implemented with. Furthermore, the thesis aims to validate the hypothesis that the file size of binary file format written with FlatBuffers serialized data is more compact compared to other vector graphics file formats, such as SVG and DWG.
In this thesis, the main topics to support the realization of the goals are 2D drawings and file formats, as well as data serialization and tools to implement serialization. Furthermore, these topics include subjects, such as vector graphics and data types.
The outcome of the thesis was a schema file for the thesis commissioner, Trimble Inc. Additionally, the thesis validated that the schema is functional by implementing data serialization with FlatBuffers and writing this data into binary file format. This was done separately from Tekla Structures as a prototype project. Furthermore, the SVG file was created and converted into DWG file to compare file sizes. By comparing all three file formats, it was concluded that, with a substantial amount of data, the file size is smaller in the binary file format consisting of data serialized with FlatBuffers.
