To All,
You can get a lot out of the simulation when looking for something just need to enlarge  the view and start
the movie.
See attached as this is not apparent by just looking at the path lines.

DAHHHH..... ! hold on here, as what i say can't be right for that line. There is a problem in the paths that are displayed.
Didn't notice it until I looked at the clearance anad path lines on the rest of the picture.
Too focused......time for a BEER!

ART,
Just an attempt on a way to clarifying the tool to the path.....
Would it be helpfull to have a "prelude tool view" which would show the cut without generating a pass? The prelude view would show the tool based on the tool inputs against a straight line, corner, and say min radius. That "view" would tell me that what input won't work too well before clicking OK in the tool dialog. In fact it could be right along with the tool picture. Maybe appear again in the rough profile dialog box but this time
including the depth cut

Picture this one based on the definiton:
 Use Tip Center  - when selected  will discriminate between using Mach3's offset registers with compensation, or just to create the code as pre-compensated using the tip radius as that compensation from tip center. Consult Mach3 manual for use of offsets.
Then picture the flank cut depth added into the above but only now rotated on some angle.

See attached pictures.
Make any sense???????

ART,
Dont't think you have to add any more graphics for path add lenghts on either side.
The display shows it and simulation will confirm all paths. At most the scale bar could expand
with no divisions indicating unrequested length has been added in the cutting as compared
to the DXF of the profile or just a note in the project information.

The real concern is the cutting down to X=0 / "cutting off the piece" which seems to
be generated on the second rough finish. Also the tool NOT cutting away material
in the undercuts when you would expect it to.

Just something a little different here to test the point tools stuff on a small piece.
The dxf file posted in reply #946 was shrunk to 1/10 it's size so diameter is only 0.1".
You know i had to do one of these!  ;)
     PICTURE                                                        COMMENT
1. 63_COMMENT_HCIR_1........ ROUGH -looks fine
2. 63_COMMENT_HCIR_2 ....... FINISH / ROUGH -  Other than the silly 0.001 extra removed
    is fine and left the tool on for size comparison.
3. Just some info on the tool bit.

Using a TRIANGLE and then a BUTTON tool to do two progressive paths.
     PICTURE                                                        COMMENT
1. 62_COMMENT_HCIR_1........ ROUGH -looks fine, no gouging
2. 62_COMMENT_HCIR_2 ....... FINISH / ROUGH -  path into center line generated and a small piece missed even though
   it would have been picked up with the finish pass.
3. Just a magnified view of 1 &2
   
Ok try another one.

     PICTURE                                                        COMMENT
1. 61_COMMENT_HCIR_1........ ROUGH - extends Z travel. Clearance looks ok except for round the hubs
2. 61_COMMENT_HCIR_2 ....... FINISH / ROUGH - Cutting to the centerline? notice the path generated but no volume removed
    even though total volume changed

Looks like the button is doing a better job than the groove. Similar and different problems.
Ok try another one.

Using a groove tool to do three progressive paths.
     PICTURE                                                        COMMENT
1. 60_COMMENT_HCIR_1........ ROUGH - Inconsitant clear around profile. Red is what should have been included?
2. 60_COMMENT_HCIR_2 ....... FINISH / ROUGH - Extends Z travel?. Stll missing in between? No clear left on a number of places?
3. 60_COMMENT_HCIR_3 ....... FINISH / ROUGH - Tool width was cut in half. Still missing in between? And missing removal of some material?

Now i will try a different tool.

Art,
Regarding how it has come overall is an understatement. Didn't really realize it untli  I started re-working the manual and then it dawned on me that's it was a re-write. A lot of problems have gone a way, improved graphics, etc.. It was interesting to see that you could slow down
the simlulation and then if you wish stop it and just zoom in and and actually see whats left, measure it  / whatever. I was thinking of tryng it out and then taking a magnified picture of the part and compare just for kicks. 
Thanks for the efforts!

I was going to do some actual cutting with code from LazyTurn but the finish pass stiffled that.
Don't think you should get that hung up on the finish pass. i say that since, i would probably do
two finish passess anyway based on what was left. Maybe even three depending on the part. The second finish cut would remove  1 to five thousands. I would let the first one just get rid of the nooks and crannies.  I haven't gone in on a whole bunch of different files to see what what kinds of "nooks and crannies" for the finish pass are left from the rough finish passes.

For example, using a round tipped tool, i would deliberately change the depth to 1/2 the  preceding depth. This way the big bumps left by a round tool should be much more even.
Or possibly change to a different type tool to get rid of them.
 
Then it's a matter of using whatever number of profile / finish passes to get to where i want to be.
 
So yes if you gave the single profile, and could post, would start actualy doing some cutting.

Face it, it's more fun than zooming in looking over a whole bunch of files.  ;)

Yep, that's when adjusted. I actauly bought two of them so will have to see if the other is any better, but expect not

Chip,
Guessing  your about to say, that after you have reached a rough with no more stock to be removed,
and if you do another after the second one, no stock or volume should be removed????
You should get a message saying that no more material needs to be removed and that it's ready
for a finish cut.
