Russ,
How about instead of rules we change the verbage to guidelines / whatever .......
There is a section / appendix, currently called Practical Machining Considerations, that will try and talk
about what you said in reply above. I am thinking this section would be same as the drawing one but different subject.
If you have any more, just post your thoughts in any manner,   and will question for understanding of them later.
BTW, That section hasn't been worked on for some time.

Thinking out load on RULES.......There are going to be some for sure, I am thinking that a rule will be
something that just needs to be done because of say some limitation or restiction in the software.

----------------
I am still playing some with the roughs and finish passes....
Let me try to explain, larger profiles are easier, small ones can be more difficult i think, as the inputs become small in value
 verses the profile the calculations approach very small  values and then passes are affected. It could also be influenced by the number value combinations.

On a convex or concave curve the pathing seems to struggle  with that small remaining volume.

Now from a practical point of view, maybe it's insignificant, in that the machine dosn't have the capability to do or maintain  the number passes anyway.

One last ramble.....
A user dosen't read anything, just uses nonsense or improper tools against a crappy profile and wonders why something dosen't work,  but sometimes that is exactly what finds a bug.......

Hacking away when in the mood,  :D

Chains can be moved to different layers. You can't move an entity to a different layer or change the order of the entity.
Tolerance is covered in section 6.2.3 and also 8.2. As far as not having to move chains or setting up a job for LC, consider / see section 5.4. Joining entities and chains are covered in Tutorial#6 section 2.0.

Clive,
Did you turn the spindle on? Even if it is manualy turned on you need to turn it on software wise.
Type M3 in the MDI line. The software then starts looking for pulse to display RPM. This was done so low rpm values would be displayed.

Dumb beginner,
You are never to old to learn something new. Don't be overwhelmed by all that you read.
The best thing i could recommend to someone is that they spend some time with a CAD program and learn to
to draw something. Even with the most advanced CAD programs the average user probably only uses 5 %  of the capabilities. It's just a learning curve and it is never ending.  Once you can draw something in CAD than a lot of doors
open allowing you choice of what and how to do something.
The problem with CNC is that includes Computers, mechanical, electronics, software, machining, etc which covers a lot of territory and is related. You don't need to be knowledgeable in all and getting a flavor of them to get by will come with time.

Maybe take a CAD course at night at the local college for a few bucks, hey, i heard that the class is filled with only the most beautiful gals, so even if you don't learn anything, the eyesight will improve........ ;D

Come on now, Al..........without the little metallic fuzzes on the calipers i personally would never be able to tell
if the measurements taken were North, South, East or West....... ???   ;D

Russ,
See attached, i may be confused.......the tool will follow the path line and when it does it will cut some of that material.
dosen't matter if it is a rapid back or at feed rate. I would need to simulate again to see the direction of travel.
Placement of the tool is based on the center of the tool tip radius and i just spotted another in green outline. When i zoomed way out the dims were ok, just that the display didn't seem right.

Yep, i can get it to do the piece, change tools or rough / finish combinations that would work nicely. Your comment on enlarging the stock or reducing the tip radius is understood and used here.       BUT
Rather than just using tools that make sense, I just try to break it / find faults  and not necessarily make it work.........at times....... if that makes any sense.

I wish we had a hundred folks like us in here as there are so many combinations to try. Intuitively we seem to find bads.  

I didn't go back and check ART's definiton on the placement so i could be goofed up.

ART,
This set of conditions will make LT close / bomb!
See attached.

BTW, I think you knew i would try this file and it's all a set up and your laughing you ask off.... ;D
