The graph above shows recall performance for the first 200 parts returned of a database of 6500 3D parts.

Recall is calculated from the number of hits returned divided by the total number of hits in the database. Recall will increase as more parts are returned and the steeper the curve, the better the system performance. Two plot shown here: the blue graph shows the performance using a detailed original model.

Search Speeds

Tests on the above 3D database with, show that the coding speed for a 3D model is <3 seconds, with searches being equally as fast. These times were taken on a standard personal computer of modest specification - 2.4GHz Pentium 4, 2GB memory. Most CAD workstations can be expected to be more powerful than this.
