Double click on the angle mate and you'll see the value for it. Get the dimension name and then you can use that in the DT.
- Open designtable
- click in the appropriate field in the designtable where you'll be wanting the title of that column to appear
- in the model go to the mate in question
- this will show you the dimension of the mate
- if you now click on the mate it will populate the title in the designtable column as well as fill in the found number in the row beneath it
In short, the same thing one can do to add any kind of dimension to the designtable but one just has to know that it can be done in the same manner.
You can also copy and paste the dimension name (after getting it) in the DT
I do this lot many times.
