| Summary: | This work describes the design and implementation of an instrument for assessment
that would enable Mechanical Engineering Drawing (MED) to be evaluated
automatically by using the computer. A prototype of the Computer- Aided Marking
System For Engineering Drawing System (CAMSEDS) could ~place the existing
manual marking process. The CAMSEDS framework begins from the display of
objects that are generated from the lecturers' and earners' AutoCAD 2000 drawings
that have been changed into the DXF files. The geometrical data are extracted and
analyzed by comparing geometrical rata from the lecturer's and the learner's drawing
automatically or a semi- automatically for similarities and differences between them.
In CAMSEDS, the empirical data is compared in order for the system to automatically
evaluate based on the following criteria: drawing entity, the entity of object accuracy
and the accuracy of measurement. The semi-automatic analysis also involves manual
assessment to evaluate the accuracy of a design based on visual I how that CAMSEDS
prototype would help in reducing marking errors, in comparison to the present manual
assessment via computerized MED. The formulas for quantitative assessment that
have been proven effective in making CAMSEDS assessment more relevant and
consistent are (1) formulation of assessment for drawing entity (2) formulation of
assessment for the entity of object accuracy. (3) formulation of assessment for the
accuracy of measurement, and (4) formulation of assessment for visualition |
