filing holes2

[roger johnson]

Newbie : Thought I had this hole filling business licked...apparently not. !

Im starting a 3d zephyr session in zephyr free 5.016 and then importing an stl file eg the rosetta stone

this loads and displays fine but when I select filter then only fill holes selective is actve and choosing it seems to hang my pc ...

what gives?

TIA

[roger johnson]

is this likely to be the stl or something else? The stl is found at

Hi Roger,

the fill holes filter may take a long time depending on the nature of the mesh. The watertight filter requires that the mesh is structured.

It's a big mesh so it's normal it's taking a long time. Try decimating it eventually.

thanks for pointer. Ive tried the fill hole option with a smaller mesh eg one of the benchy stls ...

this is about 11mb compared to the rosetta at 71Mb and although very slow does eventually complete.

from what I understand the option to fill hole watertight is not an option I can apply because it is not "structured" ... I think.

im trying to crop the face of the rosetta stone as thin as i can, using the cut with bounding box to effectively decimate it but retain quality of scripts.

will let you know later if i succeed

I guess I expected the cut by plane and export function to work like meshmixer..

Pity 'cos the zephyr cut by plane function seems more useful

[Andrea Alessi]

you can use the cut by plane or bounding box and then eventually fill holes again. To use the watertight yes, you will need to structure (which you can't, in lite) or use a structured dataset (meaning, originating from photos, which of course you can in lite). in any case zephyr is a photogrammetry software so the cleaning tools are basic, for advanced geometry cleanup you should use other software that is specialized for that, e.g. blender

Z-Brush can easily fill the holes and then you can do a remesh to get all quad geometry. Prob 30 day free trial.
