Hello,
I'm trying to make a bevel gear and ran into an issue with the circular patern.
First, I'm trying to make bevel gears with Involute tooth profile so I'm not using Design > Bevel Gear in assembly.
I am however using the the Design > Spur Gear feature to obtain the involute tooth profile. (Export tooth shape)
Next, I create the the Bevel gear blank
I then project the involute tooth profile onto the blank surface using 3D sketch.
Then, I try to create a loft cut but can't since I can't select the 3D sketch. I am able to create a surface using a loft which I then use to "Split" the body.
I then use the edges created using the "Split" feature to create a loft cut. (which is strange since I couldn't use before) I finally get one tooth but can't use the curcular pattern because theres an error. 
I've made many bevel gears that I 3D print and don't know why it isn't working.

Hi! I don't believe the gear is cut by Loft surface. Do you have the path and the profile for cutting the teeth? If yes, I suspect you will need to use Solid Sweep to create the geometry like the cutting tool.
Many thanks!

Accepted solution
Thank you for your suggestion but I was able to solve the problem.
The problem was the projected 3D sketch was on a conical surface and the Loft feature didn't like it and refursed to use the sketch to create the feature.
I solved the problem by creating a plane tangent to the conical surface through a point and projecting the involute tooth profile on the plane directly. Then I performed the Loft cut and used the circular patern and complete the 3D model.
haha I felt kind of demoralized but I'm glad I didn't quit.
Here is the difference between the the modeled involute bevel gear and a generated bevel gear using the Design tab.
