I need for a art piece to create a scribble to be 3d printed. I am trying to make 1 irregular line with a perfect tube of 1mm constain diameter.
I tried to loft or sweep with two circle on each end of the "scribble" but no success...
Anyone have an idea how i could give a colume to a 3d spline?
I have attched the itp to give a better idea what i am after.
Solved! Go to Solution.
I can't open the file you have attached bit is it something like this? I drew a spline to start and then I started the work plane command and selected the spline close to the end I wanted to start on and then selected the end of the spline itself to attach the plane. I created a sketch on theat plane and swept along the path. Hope this helps.
I managed to create a plane perpendicular to the start point of the 3D spline and sketch a circle thereupon. I even managed to pick the 3D spline as the path for the sweep. The problem comes that a self-intersecting path is not compatible with the sweep tool. Perhaps multiple non-self-intersecting splines would do the trick? As a 3D printed item I suspect you'll actually want the wire to intersect itself here and there for structural support.
Inventor 2014 is supposed to allow self-intersecting sweeps
but I could not get it to work with this "scribble".
My suggestion would be to start out with a much simpler scribble, get it working, and then gradually increase the complexity.
If you are interested in one that doesn't self-intersect (and/or do not have access to Inventor 2014 as a student http://www.autodesk.com/edcommunity ) you might try this one
Just ran a test - in 2014 I could have a self-intersecting condition as long as it wasn't "too" much.
JD, according to a recent post answered by a adesk employee, a sketch can self intersect but a single surface created by that sketch cannot. The example I believe was a spring. If the swept sketch was a circle, it created a single surface that failed. He split the circle into two halves so that the top semicircular half surface intersected with the bottom surface. That allowed the sweep to suceed.
Please see my post: Demystifying Self-intersecting Sweep
Your case belongs to Type 1 mentioned in my post, so this is not allowed in sweep.
