Hi Jim, Mitch
Does any tool path calculation use a tool center mesh ?
I mean bull nose and flat tools ?
And five axis ?
TIA
Flat tools use the center of the cutting end. Bullnose in 3 axis surfacing are more complicated, from what I remember, the mesh needs to be offset the nose radius, and intermediate paths calculated as if the cutter was a ballnose of that radius. Then those paths need to be offset in 2D to the “inside” by the radius of the cutter minus the cutter nose radius. Hope I got that right, I don’t know how gouge avoidance is done in those cases. Maybe jim can chime in here…
5 axis with a ballnose should be similar to 3 axis, except you can choose the angle of the cutter to the surface normal.

Thanks Mitch !
Arcam electron beam melting is simple, and makes strong parts from several alloys. Resolution/tolerance is 50 micrometers. more info: http://www.arcam.com/
This has nothing to do with the discussion of how toolpaths are calculated…

That said – I gave you the wrong file. Attached is a 100k quads version of that statuette. Zbrush is simply unbelievable.

Alias and Fusion are not the only competitors of Rhino. Compared with Rhino, KeyCreator has smaller market share, higher price, no plugins, but higher rating among its users. This video explains organic surface creation with KeyCreator: https://www.youtube.com/watch?v=BQih-HoGTs4

Rhino (Rhinoceros 3D) price: $995
Autodesk Alias Surface price: $22,680 for 3 years
KeyCreator standard price: $2,620
Autodesk Fusion 360 Ultimate price: $4500 for 3 years
i saw you post this in a different thread too.
what are you talking about? are you sure you’re getting current info instead of something a few years back?
like, i don’t think there’s even such a thing as fusion360 “Ultimate”
?
(i don’t actually know even though i use the software… genuinely curious about the differences between ultimate & non-ultimate… i thought all the functionality was included in the standard version @ $300/yr)
Without any additional research, I copied this from the Fusion webpage:
Fusion 360 is as low as $25 per month on an annual subscription, or $40 month to month.
ie. $300 a year.
Fusion 360 Ultimate price: http://www.novedge.com/autodesk/products/11729
Alias Surface 2017 price: http://www.novedge.com/autodesk/products/9978
So you are basically paying 100$US a month for NovaEdge support. Plus this is only available in the USA …
Or get it direct from Autodesk with free YouTube support …
i checked around and found there was a time a couple of years ago when fusion had an ultimate version…
for an additional cost, you’d get 3-axis CAM, drawings (like layout), and simulations… the basic version though picked up these functions in itself and ultimate was cancelled…
but, they’re bringing it back… in fact, the Ultimate release was supposed to happen today but it’s been delayed… apparently, the cost will be $1500/yr and :
“Fusion 360 Ultimate will have additional functionality in the areas of advanced FEA (buckling, non-linear FEA, event simulation etc.) and advanced machining (simultaneous 5-axis machining).”
idk, hopefully they don’t take the 3axis stuff out of the current version and make it an ultimate only feature… i’d be pretty bummed out about that.
(or angry even ; ) )
What, briefly, does the extra $20,000 for Alias Surface get you? What’s its target market?

Rhino provides a capable alternative at attractive relative cost, and is not in decline, especially (crystal ball) if continually managed as effectively as has been in past.
What elements to focus finite resource on going forward is the crux, as with anything.
Ah… but how is our stock doing?

I’ll look around and see if we can find it. It looked fine last time I looked.

It looks like they are running out of cash. They’lol never save enough to buy you out. Yay!
1.35 billion buys you a lot though…
