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!

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.

The rails are not considered clean so the sweep dead stops every region rotation, rip me, it turned into all looking pretty precise up tocheck now, maybe I want to try a few other line device than the arc
