MoI3D - Spur Gear Profile

Spur Gear Profile

This custom command creates an involute spur gear profile. It is as simple as possible – just for fun. You can specify the gear by number of teeth and its module or diametral pitch (it depends on current unit settings). Then you can use that curve to make a meshing gear.

Some vague definitions:

Module: amount of pitch diameter per tooth, in millimeters
Diametral Pitch: number of teeth per inch of pitch diameter
Pitch Diameter: Diameter of the circle you can see after finishing the command
Equation: Diametral Pitch * Module = 25.4

Unzip the file SpurGearProfile.zip into the \commands subfolder under your MoI main program files folder.
Then go to Options / Shortcut keys, and add some new entries, like:

G SpurGearProfile

Great Tutorial Ralf!

FINALLY got the sat import of the extruded gear to work. :D

Note: In order for import to work, it is necessary to set the unit option in MOI3d. I used Millimeters.
Otherwise I got this:

Was unable to import any 2d profiles from Moi3D directly into Alibre.
Using "3dmCurves2DXF" converter mentioned on the MoiWiki, to convert the SpurGear.3dm extruded spur gear to a 2d DWG file, which was then
imported into an Alibre drawing, 2d sketch activated, and the 2d spur gear DWG file copied and pasted into a new Alibre Sketch, which could then be extruded.

How to use this in ADEv24 ??
As described above in Dec. 2010:
Create the SpurGearProfile with Moi 3D -> Export as SAT or STEP
and import with Alibre Atom3D or Alibre Design, regardless of the Alibre version number.
