Sweep between solids is incorrect and having problems in assemblies

Jose_Montalvo

Hello,
So I think there is an issue with an incorrect sweep that I made. When I bring it up in assemblies the different parts break off.

On Sketch 3, I added a tangent constraint to the sweep path where it connects to Sketch 2 and it appears to resolve more cleanly, is this what you were looking for?

Here is the assembly location.
I had to fix the whole knife part to prevent it from moving apart

That was it, thank you! Do you have any idea why this works or can you point me to technical reading?

Glad to hear you can move forward now.
I'm fairly new to OnShape myself, but going through the Learning Center self-paced lessons.
When sweeping, the orientation of the profile to the path is preserved along it's length to keep the cross-section consistent.
If a more oval cross-section is desired, I suppose you could start at whatever angle you like and simply sweep into the geometry instead of terminating at the surface.
