The memory of the architect: archiving 2D and 3D born digital architectural archives
- 1. The memory of the architect creation and preservation of born digital architectural archives Henk Vanstappen, immd.be
- 2. CVAa: Centre of expertise coordinating the archiving of private documents on the architectural heritage in Flanders.
- 3. research questions 造も survey: how are digital architectural archival records created and managed?
- 4. research questions 造も survey: how are digital architectural archival records created and managed? 造も case study: what steps are necessary at ingest and preservation?
- 6. objectives 造も understanding of process of creation and management of digital archives. 造も anticipate problems with digital sustainability. 造も exploring possible win/win solutions.
- 7. design proces? Designing is done with pencil and paper. The CAD drawing is made by an employee.
- 8. design proces? Designing is done with pencil and paper. The CAD drawing is made by an employee. We import an AutoCAD drawing into Sketch-up and convert it to 3D. The result is printed and updated with marker pen. We scan it again and edit it further in Photoshop.
- 9. lesson #1 An understanding of the design process is a prerequisite to make decisions on preservation actions.
- 10. importance & use? Our archive is a tool we use daily.
- 11. importance & use? Our archive is a tool we use daily. Files are moved to the basement once the acceptance is signed. Well only consult it in case of a legal dispute
- 12. lesson #2 Tell me how you use your archive, and Ill tell you how well its ordered.
- 13. lesson #3 Once a file is older than 10 years, attention and care declines dramatically.
- 15. file format obsolesence? Sometimes files cant be read. We then try to find a printed version and scan it.
- 16. CAD software
- 17. lesson #4 Architects have little issues with compatibility of files, formats and software for now.
- 18. security & back-up? Yes, its something we should do.
- 19. lesson #5 Some architects like to live on the edge.
