Dealing with segmentation file (converting .vtk to .step)

ParaView Support
1

Hello,
I have imported .vtk file as a segmentation of skull model using ITK-SNAP program.
I want it to be saved as .step file format so as to use it for my 3d simulation program.
Is there any way to save .vtk file(it shows as volume) to .step file?

or,
is there any way to save the model filled as a volume?
I already used ‘contour’ filter but the inner side of a model was hollow - since it only captures the surface.

Any suggestions will be more than welcome!
Thanks in advance. My model is as attatched:

No

is there any way to save the model filled as a volume?

Your .vtk file is already a volume, what you are showing is a volume reprensentation which can’t be saved in itself.

Any suggestions will be more than welcome!

What are you trying to achieve exactly ?

I want to make a model for 3d simulation: this model should be importable in CAD program.
This model need to be represented just as it looks in volume representation of vtk file.
Also it needs not to be a surface mesh since the inside of the model would be hollow.

This does not make sense, you should read about volume rendering and what it is.

Your best bet would be to generate multiple isosurfaces.

i’ll try,
thanks.

Hi! I’m dealing with the same problem, did you solve it?
Thanks!

I gave up using Paraview, i converted into stl model and just filled inside the surface using Fusion 360.
