how we should draw a profile sketch with relation in the parameters, which options are useful. provide me a tutorial
In Catia you can only define an involute by using a mathematical expression.
Otherway you have to copy the involute from other 2D files like DXF, DWG etc.
In common way you use macros or external software to import the gear profile.
you can check my gear box model.
yeah but Santhosh ask for drawing profile in catia.
Of cource your model is correct - you can manually draw the involute in Catia. But it is only useful to learn to handle Catia and of course it is good for student projects. But if you want to design gears professionally other methods are more effective.
