Sculpt

[Al_H_C]

Hi All,

Looking for some help with what is probably a fairly basic 3d Modelling operation. I have a series of planar surfaces arranged to create a relatively basic object. I am now trying to use the sculpt command to convert these into a 3d solid but keep getting the error message;

"Modeling Operation Error:
Operation did not add or remove material.
Solid creation failed, no watertight volume detected."

Is there any way of;

A. forcing the sculpt command to work through altering some sort of fuzz distance option etc?

or failing this

B. identifying the non compliant sufaces involved so I can attempt to tweak them to suit?

Thanks

Al

Post a copy of the drawing you are working on so we all know what is being discussed. Maybe we can determine the source of the problem.

The surfaces must contain a "watertight envelope" to flood fill with material. The edges do not need to be trimmed to intersections - they can overlap, but they must at least meet forming an area that if you imagine yourself within that area there is no way out - ie watertight.

As far as I can tell this is the case. Is there any way of highlighting the source of the leak so to speak so I can atempt to fix it?

Thanks

This is where I think the problem lies.

ReMark,

Thanks for taking a look at this. I agree that this is likely the problem surface. Any recommendation on the best way to create this surface to achieve the "watertight volume" required to utilise the sculpt command. I've tried redrawing this surface a few times now with pline and _convtosurface but keep getting the same problem. I'm not exactly a pro when it comes to 3d commands so I might be going about this the wrong way.

Thanks

Not at the moment. I'll try taking another look.

On second look it seems there is something odd, in my opinion, with that corner regarding the two objects in red and green that appear in the image I posted previously.

Try running the command on this one. (see attached)
(why use individual surfaces to create such a simple part?)

Modern CAD programs like Autodesk Inventor will show you where the gaps are (and stitch them if desired).

I didn't try Inventor Fusion, but it might have also solved the problem.
