Wondering if this swept profile is possible
Wondering if this swept profile is possible
(OP)
This is the type of check valve found in veins. I would like to know of a way to model these valves quickly. My intuition was that I could revolve sweep the profile with a constraint on the inner diameter of the tube. This doesn't appear to work (although it showed a preview of such while I was playing around with the settings...go figure.)
Any help would be appreciated!
Thanks,

From the inset image it looks like a simple revolve of the valve section would suffice.

THe profile looks like its just 2 sketches and not a closed boundary. If its not closed then I would suggest that use a Surface sweep.
Its hard to say without having something more to work with.

I work with the group that did that project, but the way they did it requires a lot of operations. I was hoping to make it quickly, since the project I'm working on requires several of them. Compared to them, I've already made it a lot faster, but I would like to have it done in one operation like I mentioned in the first post. I'll try the suggestions later, and see if I can make heads or tails of it.
Thanks!

Don't forget to use a pierce constraint to attach your profile to the guide curves.

The problem I'm facing with the deform tool, which is completely new to me, is that these primary features intersect. Based on the tutorial and help files, I don't believe the tool can be used on single bodies.
RE: Wondering if this swept profile is possible
with this shape the closing part of the valve is going to have to be an offset of the larger outer oval, but the smaller oval is only used to extrapolate the location of the profile.
splines are better for the profile when you want a surface that has no joint lines.
RE: Wondering if this swept profile is possible
Can you make it so that the bottom slot shape can be raised and have the now Horizontal Line rotate for closed condition?
This could be done a number of ways but my thoughts are 3Dsketch if not already done that way or Ruled Surface with an angle.

using splines for the profile and the path.
first tried it like you did using the large upper path and got this (fail)

then by picking the smaller path it worked, apparently it will build starting with the smaller path and going larger, sort of makes sense.
this is one spline sketch (smallest oval) for the path that is offset for all the other oval sketches

Anyway, I didn't have a problem getting the preview in my picture to model. Sorry I wasn't clear on that. The problem with doing that is, when the outer portion is trimmed off, the geometry isn't want it needs to be on the inside wall; not to my liking, anyway.
I just find it hard to believe that this awesome program cannot solve the geometry the way I want, and much more believable that it's my deficiency in knowing how to provide the proper input. A dynamic profile is featured in several solidworks tools, so I'm sure it's capable.
RE: Wondering if this swept profile is possible
you can get a profile to change shape as it sweeps with guide curves
here's one of the photos again that didn't show up, this is the successful loft with all splines.

The Deform Tool does work on single bodies I believe. It requires that you pick a solid body then perform the operation. If you have two SolidBodies which you could create as unattached Extrusions or Thicken Features you can do a loft and get Tangency and Curvature Constraints for start and end of the feature.
I have a model that I can upload later. Another Feature to look at is the Boundary Solid which is in the Extruded Solid Flyout. It's like a boundary surface except you can create a Solid by picking boundaries in multiple directions.
For now I'll attach images of the Loft and Sweep approaches I used.

RE: Wondering if this swept profile is possible
here it is with two boundary surfaces, (stitched and solid)
thanks to your tip of the adjacent (deleted) bodies to get tangencies

RE: Wondering if this swept profile is possible
here's your loft method with a spline oval, a flat bottom and just 2 deg draft on the top tangent surface to get the loft to work.
I couldn't get the sweep method to turn the sharp corner on the bottom spline oval

RE: Wondering if this swept profile is possible
Glad you enjoyed my model your surfaces look good. Try to see if you can do a Surface-Surface Loft using the two surfaces to get a solid instead of knitting and using thicken with Make Solid Body.
I see you have Real View enabled. I'm currently using an unsupported card but I do my own tech support. I've always hated the classification of Gaming/CAD Graphics Cards. You'd think 1 card could do both but then the Card Companies wouldn't make as much money.
