[quote user="Mini"]oPH.SelectByAccessString("HatchSpace") is false[/quote]
So it means it does not exist ... and you probably dicovered a bug in MicroStation, because the access string exists in the list but cannot be used.
The true is that spacing is not displayed in Element Information dialog also, so maybe this access to hatching is not implemented in V8i (but is enhanced in CONNECT Edition). In such case I am afraid the only way is to use MDL (or at least VBA wrappers for MDL functions). But often it's not simple way.

Interesting is that spc is also VBA function. Isn't there naming conflict?
