[V8i] Level Filters & Regular Expressions

Question

Is it possible or ever likely to be, to use regular expressions with Level filters? 
 for example; 
 [^abc], which is anything but abc, or negative lookahead: a(?!b), which is a not followed by b 
 Alternatively, is the a method of doing this type of selection?

Hi, 
 as far as I know regular expressions are not supported by Level Filters, but general not so complex expressions can be used. They are described in "Using Filters" chapter in MicroStation help file. 
 With regards,

Hi 
For the [^abc], which is anything but abc. Try to use "- abc" (no "") 
For the second: a(?!b), a which is a not followed by b Try try "- ab" (no "")
