Can't slice 3dsolid with surface

[nic6911]

Hi. I have a surface where I would like to make a mould of the inside. I have done this before with other surfaces imported from 3DSmax by placing it in a solid block and use slice, but this one just won't do it!

 

I get this error:

Modeling Operation Error:

Inconsistent face-body relationships.

 

I have attached the dwg file here.

I got this result using the SLICE command only after changing the orientation of my UCS. Problem is I have no idea what to do with it now.

ohh yes, that is because I placed my surface inside the solid now. When I got the error I had the edge of the surface visible at the top of the solid when looking at it in conceptual. I have done what you are doing, but I need a mould of the inside of the surface...

 

In the jpg I have attached, You can see the surface in the solid. I wan't to keep the solid inside of the surface and get rid of the solid outside...

Your surface does not completely split the solid - therefore this will not work.

But even if I place the surface only half into the solid it won't slice. I know in the dwg I attached the surface did not split the solid, but I have tried with the surface splitting the solid.

I have done this before with succes, using a similar surface, but with this surface I just get the error mentioned in the first post..

Frankly, I never bother to use faceted planar surfaces for something that should be smooth.

I would use the import only as reference in doing it right. (Loft and whatever else needed...)

[nic6911]

Okay.. But I don't have the time for drawing these surfaces again. So I use the method of slicing it in a solid. It have worked so far, but just not with this surface....

Maybe there is an anomaly in your surface?

 

I think I may have found a problem with your geometry at the stern of the hull. Take a real close look at the seam near the bottom. It appears there is a gap.

 

It's worse than I thought. I have discovered a gap on both sides as well. Or is this an anomaly of my video card?

Take a close look at the two areas circled in red. A very close look.

This is a closeup of the bottom corner where the side/back meet the bottom of your hull. It's the same thing on the other side too.

You have the same problem here at the back of the hull near the bottom.

Here is a closeup at the bottom (centerline) of the hull.

 

Your attention to detail has taken a serious hit. These gaps may be what is causing the SLICE command to fail.

Okay... That is a problem yes. Hmm. I guess that it is too much trouble fixing this. Thank's for the reply's everyone, I think it will be easier and better to find another model or draw one myself when I get the time...

[ReMark]

Typically when you see that error message your first thought should be to go back over your geometry and look for inconsistencies. With a model this complex you really have to get in close to find problem areas as they won't be immediately apparent.

Thank's for the reply. I think I have learned my lesson now

.... I guess that it is too much trouble fixing this. ....

 

Trivial to fix in Autodesk Inventor using the Stitch command to pull together open seams like that, but it would still be faceted planar faces - so I would just do it over correctly....
