So, I know I've done this in other models but apparently I've forgotten the proper setup to create a new part within the assembly that is a 3D sweep from one fitting to another.

When I create a 3D sketch on its own and then go to Insert > New Part, then I can't select the 3D sketch for the sweep path because its not within the part I'm doing.

So, please help refresh my memory. What is the easiest way to create a tubing profile and then sweep on a 3D sketch path.

I would create the sketch in the part, but in the context of the assembly. If you want the sketch at the assembly level, then you need to duplicate it in the part. Does "convert entities" work on a 3d sketch?

That's not working because you can't directly use an Assembly sketch for a Part feature. Create the new Part first, with nothing selected. Edit this Part within the Assembly, create the 3d sketch, and then you should be able to perform the Sweep function.

If re-creating the sketch is too much trouble you should be able to use the "Convert Entities" function to reproduce it in the Part, but unless the sketch is very complex I wouldn't recommend it. I'm afraid that would add another layer of complexity, and be more prone to errors, though it may work fine.

Ok. So the part I was forgetting is that I have to start an empty part first. I don't need the sketch in the assembly, just getting caught out by doing things "normally" in preparing everything first then creating a part.

I appreciate the help. In a bit of time crunch and i could let you fine folks tell me instead of dorking around relearning this. Thanks!

NEVER use an external sketch/curve/edge/face to create a feature. ALWAYS copy entities into an internal sketch or feature.

There's exceptions for everything. There are also exceptions to "There are exceptions for everything." NO EXCEPTIONS!!!

Interesting. I was doing...
In Assembly
Insert > New Part
Click in Empty Space
RMC on New Part and Select Edit Part
Create 3D Sketch
Create 2D Sketch
Feature > Sweep
Exit Part
