Helical gear

[mortada1998]

Hello everyone, I am facing a problem in forming a helical gear. I drew the front view and used the sweep tool and put the angle of the helical in the required twist box, which is 20 degrees, but it did not work. Please help me learn the correct steps to implement this. As shown in the staggered picture, the teeth do not mesh with each other properly due to the angle difference, noting that I set them to 20 for both gears.

No dimensions - where did you get the tooth profile?

Tooth profile must be perpendicular to the start of the helix path and probably requires Sweep-Cut with Solid to achieve correct geometry.

Pattern Features, not sketch elements.

I designed the gears in the design accelerator located in the assembly section of the Inventor, then modified the resulting gear and made a projection of the geometry, and then I copied this projection and pasted it into a new file. Please, can you explain the correct steps to do this? I am still a beginner
