GearHeads Forum

Just watched it dan..yes, looks like their bogging down on line segments.. which is really quite odd when you think about it.. I mean, a single gear isnt that many points.. But thx, It leaves me with some things to think about in terms of how to make it better.

The vid of the fix is here Art if you watch it you will see when I do the first delete how much fusion bogs down, I crashed twice doing the vid prep on the first delete.

  Yes, I suspect they all want that now. The complexity of that is enourmous though.. Im still investigating.

The impression I got yesterday from one of the dev guys is they don't wont .dxfs in fusion at all, and don't want to fix it what is stupid most of there programs still use .dxfs.
the same problem exists for .stl and obj.

they wont fusion to move to the .f3d and f3dz for fusion and import export of solid dead files what they have a converter for

these ones
IGES files (*.iges, *.igs)
SAT (*.sat)
SMT files (*.smt)
STEP files (*.step, *.stp)

these file above are the ones they wont and are doing translations for in the future you will be able to import export between programs that use the above file type and it will translate out to say solidworks and the file will be just like a solidworks file but then you can export the same file back out of solidworks and into fusion and it will be translated back to a fusion file, inventor files will be even easier to use.
so it all the big boy programs they are after trying to corner the market, you can get one of the ADSK production packages for $3500 us a year.

it would not surprise me if they knock on your door soon. so don't get realy sick they might pounce

in fusion you can use these types as well

It's up to you what you do I don't mind working out the workarounds, it's good practise for me and it helps you, what is important to me

Yes, very much sounds to me like a database engine designed to hold beziers and arcs, but not well designed
for multiple line storage.. very strange way to go as millions of dxf's with short lines are common out there..

  I will be investigating a way to swap a chain to arcs and beziers eventually but I havent as yet added such curves
so that may take awhile. Internally, I will be converting all entities to short line segment contours as it allows me
more easily to do intersections, offsets, simulations..etc.. The speed in fact should me much higher with objects being single
contours. So in the end Ill have to write a reverse engineering algorithm to get back lines and arcs. A persons original drawing
is unlikely to be seen again once Auggie starts to work with or simulate using it, in terms of its original lines/arcs anyway.

  I will attempt a reverse engineering algorithm once I start the simulation code. A 2d simulator is now on my planning board
for working with gravity and kinematics of contour objects.

The forum is working again.

I tried a clock face and a flourish they all have to many point for fusion to handle. after some more digging if the .dxf is made up of lot of little lines what fusion does it has a point, line point, point, line, point, point so on.

if I highlight the dxf you can see the points.

if the arc's are one continuous arc fusion is fine, if the ach is made up of a lot of sort lines that is what kills it.

the 3 images are from bad to good bad is from gearotic, ok is from rhino and good is the file I re did to work in fusion

Hi Dan:

The only way Id have to make a crv is to do the same as you, load  gearotic dxf into vcarve and export.
I suspect the issue a hires polylines. Ill do some research to see if I can change that any..  Do you know if a florish loads into Fusion.. does it have the same issue as a gear?

Art

I would not bother Art it would make the Gears ruff.

.dxf from Vcarve pro are fine, running the gearotic .dxf through vcarve pro does not fix them. it may work with a gearotic .crv that something I should try.
can I have one in .crv and .svg just so I can test them.

the dxf from rhino are fine in fusion, I just got sent a gear from rhino to test.

Dan:

  Would it help to simply reduce the point count? I could experiment with a settable resolution like the old days.. on the output, something to limit the distance between points.. though gears are so curvy it can lower the resolution..

Art

Do it when you have time Art, we are hammering them over .dxf now a lot of the guys need proper .dxf not .dwg for laser's, water jets and plasma.

I think they are trying to move to there standard and it's not working most of the contract deisginers need .dxf for there customers.

once I remember to do the conversion vid it will be fine it takes 10 mins first time, then after that a person will get faster at doing it, one of the other fusion user's use's gearotic, it was him tallying A fusion staff member off (young guy just started) that gave me the idea what to use to do the conversion so it keeps the gear to speck.

the first 5mins is deleting chunks of the gears.

anyhow have fun in the snow
