creation transmission between gear rack generator components

[Giuno85]

Good evening to all,
I'm trying to draw and dimension a dense transmission between pinion and rack through the inventor design card (old design accelerator) but despite my efforts I can't find the option that changes the transmission that by default is sprocket ralla in rack pinion.
would someone be so kind to tell me what the procedure is to follow?
greetings

I do not feel feasible, at least until rel. 2011.
the last rel. 2013 I have not mounted it yet.

Bye.

hi stefanobruno, in the end the only way to create a rack is to model it manually perhaps exporting the tooth profile from the tooth created by inventor?
the strangest thing is that in the preview of the study of the transmission it displays... there is even preview wheel dentate rack.. . .

hello to all and apologize if I sneak into this topic and I slightly deviate the topic of the discussion, but since we talk about racks...in a gear composed of more dense wheels and ending on one side with the lazy-cremagliera couple, participates in the transmission relationship such couple?
I attach an example. It's the couple 1-2 that determines the relationship, right? if I am not mistaken the relationship of transm. between 3-4 is only theoretical and equal to infinite.
