Inventor 2017 Convert Multiple Surfaces To One Smooth Surface

[m_morcielago]

Hello dear 

I work with Inventor 2017 pro

I have a full multiple surfaces part and I wanna convert it to one smooth surface 

Take a look : 

I want to remove the separate lines between surfaces

HI @m_morcielago,

that does not work, they can not just delete a tangent...

this tangent s also exist in free form:

Hello @m.morcielago

I have done a screencast on how to convert your multiple surfaces to just one surface.

Is this what you wanted?

Thank you for trying

But I have another problem with this part 

I need to remove that lines between each surfaces.

I want smooth surface like the sole

  

[S_May]

why?

[m_morcielago]

Because I need it for Autodesk Lastmaker software 

Look : 

 

In this case I need to select side of model(seamlessly) but as you see I can't do it.

It select me a single surface of side

I need a seamlessly surface for side of part

[m_morcielago]

Is there any way??

I am still waiting

Hi! The lines you are seeing on the surface are called trim loops. This foot model was created by multiple smooth trimmed surfaces. I am not a way to convert these trimmed surfaces into a piece of trimmed surface easily. In Inventor, you could try using Freeform Convert workflow to convert the faces to Freeform body. I had tried it but I did not get satisfying result due to the following reasons.

1) Freeform Convert only works on 4-sided or 3-sided trimmed surface. If a given face has a round loop or more than 4 sides, you will need to split the face first before converting it to Freeform. You could use 3D Sketch -> Curve on Face to create curves to split the faces.

2) The resultant Freeform bodies may deviate from the original faces slightly. The deviation is small but it does exist depending the complexity of the source face. I am not sure how tight or accurate you are looking for. It may not be acceptable.

3) The resultant Freeform bodies are still individual pieces. You can use Merge Edges command to connect all pieces into one. However, this process can be tedious and it can change the surface further, deviating from the source.

This is why I don't think Inventor has a reliable workflow to do exactly you are hoping for this particular case. If I were you, I would do it in the source surface file. How was the surface created in what CAD package? Another question I have is why you about the trim loops? The faces on either side of the trim loops are smoothly connected. Technically, the entire model is smooth if you machine to spec. Do these trim loops present challenge for your process?

Many thanks!

Do  you have a web link for information on this software?

Is there an Autodesk Forum for this software?

[m_morcielago]

Thank you for your attention 

This 3D part made by 3d scan technology and I have just this by this format and this shape

I'm looking for 3D surface software that help me on this project.

I cannot change source of files.

Hey guys I did it finally 

We didn't need to make these surfaces smooth

I just exported my model by .STL format and then , shoemaker software recognize it easily.

Thank you so much for your time

So really, rather than make smooth - you made faceted planes.
