Hi nice tutorial. Have had fits with many gear generation methods over the years. Seems like PTC should just build in a a simple gear function and save us all some grief. Anyway around 9:50 you talked out variable root_circle_diameter and used constant 8 when relation wouldn't verify, because earlier you declared root_circle_radius. Great videos. Keep up the great work!
Based on the research I've been doing, I don't think there is a simple gear function. The design of gears is extremely complex involving a lot of design and manufacturing functions. I know other CAD packages offer automated gear generation, but I suspect it might be highly simplified.
Hi Dave, a weird and weak method in my opinion, as it’s difficult to adapt to other situations. A good parametric model should have definition of primitive diameter, module, pressure angle, etc, etc, etc. I think much better to use curve by equation for tooth side and having all gear parameters to easily pass from a gear to a different one. A correct pattern should be obtained by an extruded cut and an axis pattern. Anyway thank you for working during vacation too!! Merry Christmas from Italy!!
Sir how we make details drawing dwg files without any changes when we make files its dim. Colour or dim. Style will change when we open in autocad this file
When we make pdf of details of product dimensions then in pdf the line are bold/thick so in pdf not seen the actual arc how we make thinner these lines in drawing
No way. It’s parametric based on the number of teeth and module. Although I think I screwed up the mirror angle in one of the videos. Should be 360 / 4 x teeth.
It remains a mystery to me why of all the known methods
creating a gear, Dave showed exactly this strange way ...
Merry Christmas to everyone!
This is the suggested technique from the PTC Knowledge Base as stated in the description.

Agree. It is easier to define it using Datum Curve, 'curve from equation' using standard gear terminologies like module, pressure angle etc.
Wait until next Wednesday’s video. As I stated in the description, I’m demonstrating PTC’s suggested technique from their Knowledge Base.
Thank you so much . It was really helpful for me .
Thanks, Mohan!
Hi i have a question, how can we calculate the diameter ofinvolute of spurs gear?
Sir how we make details drawing dwg files without any changes when we make files its dim. Colour or dim. Style will change when we open in autocad this file

No way. if u try it for different number of teeth the what? you have to again model everything?

@@CADPLMGuy yea.
