how to increase resolution of DXF output file

[kunole]

Hello,

I am new to Gearotic. Is there a possibility to increase the number of points created in the DXF output file ? Resolution is pretty low.
I am using the latest version of the software (seems resolution cannot be adjusted) ?

For example I generate an involute gear diameter 6.4 and I get point distance around 0.05.
I would like to have around 10 times that resolution.

Thank you.

Hi:

  Hmm, the usual trouble is the number of points is way too high.. It used to be adjustable,
but people failed to find the adjuster and had similar issues to yours, so I set it to much higher resolution
and the only complaint I hear nowdays is way too many points for autocad fusion to handle.

  Ill run a test to see whats up, if necessary Ill generate a special version for you to increase the
number of points..  Ill post shortly,

Hi Kunole:

  I find the distance on a 6" diam spur to be about .023 between points, as in the attached photo.

While this is probably OK for most, I can respect you may wish to have much more.. Do you really want to have
10 times that though.. .002 per point? Let me know what your requirement is and Ill try to adapt a version
specific to it and post it here so you can get higher resoulutions..

Hi Kunole:


  Here is a test version to see if it helps with your trouble, the resolution in this special version is 150 points per tooth
rather than the 50 points per tooth in the release. This gives about .007" per point on a spur. Tihs is abotu triple the
normal and seems high density to me, but if you need more, just yell, Ill give you as much as you can handle.. or as much
as the program can put out..

  Just unzip the attached to your folder to replace the original program executable..

Hello Art !

Thank you so much. Problem solved.

Good to hear. The resolution of the Spur gears in Gearotic is actually now set to a number of points per tooth rather than a
setting of distance, default is 50, the one downloadable here is set to 150, but on request I can make it anything youd like
if it should become necessary.. I just have never put the setting in the config as of yet..

I've stumbled across some recent articles on bezier curves, and how they'll greatly improve civilization as we know it; of course I can't find them now...

Seriously, after working mostly with displayless real-time stuff I've don't understood graphics.  Would these beziers, nurbs, nunchucks, etc spliney things with all their cubics and quadratics and handles be of any benefit to Gearotic.  Are they at all practical to add without making another Art clone or two?  Or are they just another rabbit hole for unsuspecting moose to fall into?

Kirk:

  A bezier or any of the others.. are really just a replacement of many points with a formula instead. Its a type of curve fitting,
where you determine a shape by a set of control points. They can be a benefit or a curse, depending on what use your putting
them to. A tooth for example would likely fit into 2-3 beziers.. but of course to be usefull their in the end returned to
points by whatever program is using them. They dont add to resolution.. and can sometimes subtract from it. But they do aid
in making a dxf smaller with fewer entities in them, this allows better use in some cad programs.
    I suspect youll see them appear in gearotic eventually. This would allow for dxf's to be better read by fusion. I have some
more experiments to run before I commit to doing so, but Im roughly planning for their inclusion in an update of the
vector system.
