Bayonet Mount Adaptation Help - Solid Sweep utilisation

I need a bayonet mount that moves in a compound path moves in both rotational and vertical directions to increase axial compression at the endpoint. I want to design the female part of the J slot with a vertical drop followed by a 100 degree declined turn to lock it in place - this lateral portion of the J slot would ideally be curved to maximise compression to give a positive end location for SLA printing.

I've seen that many people have ran into issues with fusion360s 'solid sweep' not being able to do this easily with picture 1 showing a model I created only providing a right angled mechanism.

The 'emboss' feature does not provide precise geometries and also gives a strangling effect to the female slot as it expands the curved surface. The 'project' feature doesn't provide sketches that work with solid sweep (G2 error, the blue line in picture 2).

I have found this video of someone finding a workaround in SolidWorks ((9) Two ways of Solid Profile Swept Cut Два способи побудови вирізу тілом по траєкторії - YouTube) , and I was wondering if this could be done in Fusion. Another method I have though of is using a sheet metal solid sweep and then creating the cylindrical shape after creating the female slot - however I think the geometries will be imprecise. The final method I have yet to explore is utilising 3D sketch techniques to create a path that is G2 continuous

If anyone has any insight that would be greatly appreciated curved J slot error.pngG2 error message.pngsolid sweep bayonet mount .pngStandard SLA Bayonet Design.png

If you can live with the sharp corner I have circled in red, you can break this into two different solid sweeps.

This is very good! Thank you. So I could alter this further to create a curved slope variant of the second sweep which I will try now (Want to create some options to see which prototype give the best axial compression - picture below)

Regarding the part in red, would a simple fillet not fix this - I'm new to fusion so don't understand the transitional effect of some tools have when 3D printing

Hi! I believe it could be related to the path. First, the sharp corner can be problematic. Second, the sweep path that the cylinder follows should be the inner path not the middle path (think of driving a car and making a turn; the inner wheels dictate the trace to follow).

Please share the f3d file here. The forum experts can help take a closer look.

Many thanks!

This is my current model, does anyone know how to make the second solid sweep curved? like the purple line. Thnkas!

@TheCADWhisperer has a nice tutorial for similar cam slots.
