Hi everyone ,

let's set the context....

I  have several parts in some assemblies, that have some hexagonal holes...   When detailing my assemblies or parts, i want to first put a centermark to my hex. holes.

What i can do is, sketch a temporary circle that is tangent to 3 opposite edges of my hex. hole ( thus auto centering a circle ) then put a centermark to this circle, then turn this circle to dotted line to make it seem like disapear without deleting it ( deleting it would make my centermark 'floating' ).

But that process is rather time consuming... ( imagine, on a single drawing, i can have up to 50 of those hex. holes ...)

My thought was,  would it be possible to pre-select 3 opposing edges of a hex. hole ( i mean manually selecting, before executing a macro ), then have a macro ( in VBA ) to draw a circle tangent to these 3 lines ( or edges ),  then put a centermark to that newly sketched circle, then put that circle into dotted line to ' make disapear '

Thus seriously reducing the process of centermarking hex. holes 

First, does it make sense ?

and Secundo, does anyone have a hint to how achieve this ?

( just remember, it has to be done into a view , in a drawing files ... )

Thanks in advance to all the API gurus around here ...
