I'm trying to create a simple program to machine 88 holes into my waste board for threaded inserts. The problem I am having is that I must select 4 contours for every counter-bored hole. This gets old very quickly.
I have tried dragging a window over the entire part from both left and right sides to no avail. Am I missing something, or can this not be done? One would think it's a simple action to select all possible contours with a click and drag,
Without having the model its a difficult to be sure, but it looks like your holes are on a regular pattern...so have a look at programming the first instance of the hole and patterning the result with tool dominant (order by tool).
Alternatively, export the file to .f3d and attach to post so others can have a look and comment.
