..if I/we use your shown spacing/pitch of (.96850394) it will not work as is.. but, if you check "Geometry pattern" it will allow for the overlap.

..so, what is the spacing?... that is, if I assume.. it would be about 1.15826?.. and, with that pitch it will solve (w/o geometry pattern)

Thank you !! Sir ,I made a mistake in the direction part and did not take the edge into account ,can you tell me what was the difference between using it normally and with geometry pattern . Secondly I have been taking random values , I couldn't google any double racks with pinion so had no sense of direction !

The difference between NOT using Geometry Pattern and using Geometry pattern is described here pretty well:

SOLIDWORKS Geometry Pattern Option – What does it do? | Computer Aided Technology

Basically it is a difference in patterning the FEATURE vs patterning the geometry (ignoring the feature constraints/functions)

So, I have been this far into making it ,but somehow I can't seem to fix the rack or spur gear when Im trying to rotate it.Secondly I want to copy the whole thing so that I can make a box rotating on a rack.I did this by looking at video's and they didnt draw any pitch circles. Of course Im missing on alot of things and I need to understand more ,can someone help me on this and point out the flaws.

Sorry to say this J. Mather I am trying to put the parts for the assembly but i am unable to attach it beacuse there's no option.I cannot even get the advanced reply option .
