Inventor 2013 SP2.
I have a created a 3D sketch (fully constrained) of a handrail centerline between stanchions and am trying to sweep the handrail profile.
It doesn't come up with any errors, but it won't sweep past any bends in the 3D sketch.

Solved by JDMather. Go to Solution.
Attach the *.ipt file here.
My guess is missing Tangent constraints in the path.

I won't be at my 2013 machine till tomorrow - but it looked like you might be doing too much work to create a 3D sketch.
I would simply create a 2D Right View and Top View sketches and let Inventor figure out the 3D sketch for me.

The attached image gives a better idea of what I'm working on.
My thought was that it was too complicated to use 2D sketches.
Do you still suggest I scrap the 3D sketch and use multiple 2D sketches???
It is a very simple path.
Only requires 2 very simple 2D sketches and then Inventor will create the path for you.
Took me about 10 minutes to create (in r2014).

Did you figure it out? There are 4 Bends you will have to add yourself to the path (looking from the front view) after Inventor creates the 3D sketch path.

Yeah I got it, ended up doing it with 3 sketches (top, front, side) into 3 3D sketches.
Worked a treat!!!
Thanks again.
Not the most elegant way but seriously do not know how to do it in 2 sketches very interested to find out.
Basically I worked in 3 different heights, projecting from the other sketches as needed, then for the transitions on the right I just built them on 2d sketches projecting as needed, the transitions on the left I did some surface intersection shenanigans to get them.
I did have to include all the geometry in one 3d sketch for the sweep to work though so maybe that will help.
Sorry it's in 2014 so I included pictures maybe they will help.

Cheers for looking at it, but after learning about the 3D Sketch Intersection Curve tool that creates a 3D sketch from 2 2D sketches, I'll never attempt a 3D sketch (for this sort of job) ever again. I wasted so much time trying to get it to work!!!
Attached is the Kneerail part showing how I did it for peoples reference.
Thanks for the tip regarding the bends.
The reason behind doing a single sweep is that I simply don't require any information besides an approximate overall length and quantity of standard bends. Everything else is bent and welded here onsite.
Hi! There is an issue here. The behavior does not look right. I have seen similar case before. Basically, there is a degenerated line along the path and Inventor does not like it. For the part you are working on, the degenerated line is located between the bend of 300 and bend of 90. If you recreate the lines and bends there, the problem might go away.
Thanks!
