Swept Feature 3

I am trying to sweep this feature down to a point while staying tangent to the outside edge of the part. I have attached a picture of what I am working with. Hopefully someone will understand what I am trying to do here. Any help would be greatly appreciated. Thanks in advance.

Considering that you uploaded a 3mb image file, you could have uploaded the actual part file. Besides, you'll need to supply a bit more details since your description of what you want is ambiguous at best.

Lurks,

Mark it up and send a jpeg showing what you want. Keep the file size lower if you can please.

If possible even a parasolid of the potion that you need to work with would be helpful.

Let us know your version of NX too?

It appears that the geometry isn't essentially twisted in ways there may be solutions that aren't necessarily requiring freeform.

best regards

I have attached a 2D drawing of what I am trying to do along with the model itself. I am trying to take the raised feature along the edge and taper it down to a rounded point while staying tangent to the outside edge. Hopefully this is a little bit more clear, but let me know if it is not. Thanks in advance.

By the way, I am using NX4.
 
If you want the part to look like the left side of the attached image, just put an Edge Blend on the top edge of the wall, then after applying the Blend, do the same to the bottom edge. If you play around with it a bit, I think you can get something close to what you might be wanting. You may have to add some draft to the cap of the wall or use a Revolve to create a surface then Trim Body to get the angle I'm seeing in the image (right view).

Some people are like slinkies....they don't really have a purpose, but they still bring a smile to your face when you push them down the stairs.
 
That is the right idea but I need something that gives a more gradual adjustment. I am trying to get all three of the faces to converge if that is possible. Does that make sense?
 
I need that same height up to that squared face and then from there taper down to a point. What you have reduces the height of that edge. I'm sorry for the confusion.
 
That is exactly what I am looking for. Thank you very much. Where do you find the swept feature at to perform that operation?
 
What is the best way to turn those sheets into solids to unite them with the rest of the solid model?
 
Insert>Sweep>Swept

Like I said, the sheets need some smoothing down at the runout. I took some liberties in creating the first guide string for the second swept body, so it may not match perfectly with the solid body. As for making it a solid, I would create another swept body for the floor and perhaps a bounded plane or extracted face for the back wall, sew the sheets to form a solid, mirror and unite. I seem to recall there is another method that can use the sheets directly (John?) but it's been a while since I tried that method.
 
I just went back and took a second look. It turns out that the swept can be created as a solid to begin with. Because of the nature of our products, going for the solid first rarely works out, so I generally need to use multiple sheet creation techniques to achieve what I want. Just goes to show that you need to be careful about getting in a rut when it comes to solid modeling.

The attached file has the runouts created as a solid but it doesn't want to unite, perhaps because of the spline I put in to for one of the guide strings or maybe some surface deviation on the bottom face.

I do not have that feature. When I opened your part it shows up in the part navigator as swept, but all I have is Variational Sweep, Sweep Along Guide, and Tube. I also have a Mesh Surface which includes Through Curve Mesh... and Through Curves...John?
 
Make sure that the Role you are using is one with 'Full Menus'.

As for the other means of adding a 'Sheet body' to a solid, it's called 'Patch', and starting with NX 6, Replace Face has been enhanced so that it's easier to user in situations were your new faces completely replace one or more existing faces of the solid.
