Removing hollow / convert to solid

[simmonsstummer 0]

Hi,

i would like to print a vase and i find out that the special option of spiralization is perfect.

But i think that the requirment is that you have a filled solid stl without the hollow space in it.

Since i have an stl of which i no longer has the original file to work with and i designed it already with the concave hollow part inside, i think i could not use the spiralization.

So:

I can i convert my stl to a filled solid? I would like to use meshmixer or if you have suggestions..

Thank you

in Meshmixer you could select the inner surface and delete it. In the selection section you can set a degree angle where the selection stops (crease angle thres). Select a section on top of you vase and hit F (erase and fill). Or delete the inside and use Analysis -> Inspector.

thank you so much! This could help me a lot!

But i'm not so familiar with this can you explain better how to use the crease angle thres?

when you have the selection tool active, there is a submenu on your left. The crease angle thres is a slider to set the degree angle between the triangels (hit W to see the triangles). This means that by default the slider is 0 and it selects everything, When set to 45 the selection stops at this angle and leaves the triangles alone across the 45 degree border.
