Is there a simpler way to extrude a spline and have it print?
![mitch1138](https://profiles.onshape.com/3e56308221dca60a0e5ded688fced1a3a95ed99e6bcb214f6aec3414fd5177ef.png)
I can draw a spline and extrude it as a surface, but the resulting part will not print (no extruded line is visible). I can create a rectangle at the endpoint of the spline and sweep it to create the same appearance and it will print. Is this later the prefered method, is there a more straightforward way to do it. Many thanks.

I repeated your process. I extruded a spline as a surface, and thickened the surface to form a part. Next, I exported the part as an STL.
I was able to open the part in Simplify3D without any issues. Maybe it is an issue with Cura?

You might be exporting the surface instead of the thickened part. Try right clicking the part in the part list on the bottom left to make sure you're exporting a solid rather than a surface.

I did a quick screen capture of fixing it. If you have any more questions, please let me know! Sorry for the background noise in the video. I forgot to turn off a noisy dehumidifier I have right by my desk

Are you exporting the part or the surface from the part studio?

Many thanks for all your help.
I usually right-click each part and export it separately, then drag each one into Cura. Here's a quick tutorial that I made mostly for fun that shows the drag and drop action:
The lines on the sketch are extruded (surfaced) then thickened. It is not complete but should be illustrative. Printing is the issue. Here is a screen shot:
