Description Keys & Point Groups


I was playing around with some Description Keys one day when I noticed an item that didn't give me the desired result. What happen was, I had a drawing that I had built a Description Key for and in that DescKey it had everything that I needed except for EOP. At the time I didn't realize that I forgot to put it in because I was to busy working on something else. So after the points where brought in I began to filter my data so that I could build somewhat of a clean surface. Typically, I would create a Point Group for all the points that will be included in the surface then another should I need to create breakline info off of any of the point data. What I noticed was that since I forgot to add EOP into the Description Keys it didn't get added to the Raw Description Matching tab in the Point Group properties. I know this isn't that big of a deal but it was a little surprising when I went searching for it. So of course the easy fix for this would be to flip to the Include tab and add it in manually. Honestly, I think the Raw Description Matching tab is great but what if you don't use DescKeys. I guess if you don't then you are stuck using the Include tab. Now that I look back at this I can certainly understand why it didn't get added but initially it was a little surprising. So long story short. . . if you are not using DescKeys it's just one tab you won't be able to use, Right!
