Instead of filtering on additional attributes, you can change the criteria used for calculating nearness to take account of different requirements.
Note:
Find Similar is only enabled in the advanced Level 3 databases. This exercise assumes you are using the
Level 3 Polymer database from the last exercise.
-
Find records similar to Polypropylene (Copolymer, Conductive, 5% Carbon powder)
-
Open the datasheet and click
Find Similar.
-
Re-calculate the list of alternative materials, taking Electrical resistivity into account and prioritizing results with a resistivity that is the same or lower than the reference material
-
Click the Nearness settings link on the Records Similar to dialog.
-
Under Electrical Properties, select Electrical resistivity. Set it to 100% when Same or lower, and increase the Weighting factor to 2.
-
Click OK to generate the new results.
Note: These results are conceptually different to those from the previous exercise. We have ranked similar materials, taking into account the resistivity, but there is not a fixed upper limit as there was when filtering using the Limit Stage. Materials with a higher resistivity than the reference will still be included in these
results.
