Ralf,
OK, I found the problem. I have my default spreadsheet font set to Times New Roman. I am not sure why, but changing it to Arial fixes the problem.
Now, according to a list I was given some time back (I think Max sent it to me), the types of holes that may be defined through the HPS are supposed to be as (Type ID) Definition: (1) Cylindrical Bore; (2) Drilled; (3) Counterbore & Bore; (4) Counterbore & Drilled; (5) Counterdrill & Bored; (6) Countedrill & Drilled; (7) Countersunk & Bored; (8) Countersunk & Drilled; (9) Tapered Bore; & (10) Tapered Drill. I suspect that types 4, 6, 8, and possibly 10 are improperly defined here.
I would certainly like to see the HPS tool (A) documented better and (B) developed to a greater degree. The fact is that a counterbored hole for a socket head cap screw SHOULD have either a countersunk edge between the counterbore and the through hole or a counterdrill in that location to clear the head-to-body fillet such screws have. There are several other "identities" that would be highly useful were they allowed -- and we could really use the ability to "sub-head" HPS data as we can do with File Properties->Material data (also an alibre_unicode type of file)...
