Creating a Surface with Deformations

Hi.

 

I've been trying to create a surface that has 2 lines creating deformations and haven't come up with a solution.

The attached file is a DWG with the lines to create the surface.

I've tried several diferent aproaches, from lofts to patchs but none can create that surface, but I'm pretty sure I'm doing the wrong aproach to this problem.

Is there anything similar to the Autocad Network or Edge Mesh in Inventor?

 

While I'm at it, is there a way to copy lines/splines in a 3D Sketch, like you do on a 2D Sketch?

 

Thanks for all the help.

 

Cheers.

Sounds like your best bet might be to use the freeform modeler to do your deformation. I haven't really played with the freeform modeler myself, but there's a decent video on it here:

Hi Rusty.

The video link doesn't work, but I've searched youtube and found several videos about it.
Problem is that I'm using Inventor 2014 and that's a 2015 feature 😞
I find it weird that it's such a hard thing to do.
It doesn't seem like a complex operation at all, but I might me wrong.

Nonetheless, thanks Rusty 🙂

Hello ccarreiras.

I see you've managed to create the surface.
Would you be so kind to explain me how you did it? 😛
Just a few tips to point me on the right way so I'm able to get it done.

Thanks 🙂

What is your design intent - there is an easy way that might work depending on your design intent.

Hello JDMather.

This is a part of a model to be machined in wood, in a CNC.
It needs to be as clean as possible due to be machined with a ball end mill and it uses the surface to recognize its toolpaths.

That is not at all very descriptive.
I might be motivated to work up an example if I knew the function of the part.

Maybe a picture of an existing product of similar design.

Sorry for the late reply.

Here's a photo of the product.

I've been asked to remodel it and add a few changes, wich I've done all except for the bottom part, the outside and the inside one.

I can't share the model and I might get into trouble by posting this photo but I really need some help here.

 

I hope this is what you were looking for when you asked for the design intent.

 

Thanks.

In the image there appears to be a planar face in the center - is that correct?

 

In the image there appears to be 4 ridge lines - are they there, or should that be smooth with no ridges?

 

Once I know the true design intent of these two areas - I think I can post an easy solution.

The flat area is a mistake, and the only one with ridges should be the horizontal one.
It's not a sharp edge but it's a small fillet.
