I'm just a starter.
I scanned my wife and obtained a bust. The resulting STL after repairing has a hole viewed from the bottom. Thick of it as a inverted bucket. I would like to close the bottom to facilitate printingg. Please suggest how I can accomplish this in OpenSCAD?
Thanks

Try :

x=0;
y=0;
z=0;
a=10;

import("myfile1.stl", convexity=5);
translate([x,y,z])cube(a);

Move the cube around to fill the hole. Then export as stl.

I don't think you can do any CSG operations on a non-manifold STL in
OpenScad.

If you aren't going to restrict yourself to OpenSCAD, the free program
Meshmixer will allow you to "drop" a plane surface anywhere in the
workspace, then angle and slice it in the desired manner, closing off the
opening of the upside down bucket. Even if you are not especially
comfortable with a new program, there are more than a few video tutorials
presenting the above actions, bringing rapid understanding with a few
clicks.

I must say sorry about this. It was my first question and I was confused
about the various subscription/registration processes. It was thus sent as
an email to discuss@lists.openscad.org. I realized I was stupid and now I
am using the forum.openscad.org user interface to compose the messages.

Here is a picture of the scan.

(She's not my wife but a student I tutored at a charity organisation. And I
am glad that the kids, though underprivileged, are still as awestruck as I
was when they saw their first printings. They were mesmerized in front of
the printer for twenty or so minutes just to watch the print head dance!)

I hope you can see that there is a hole in the bottom of the bust. I think
I may be able to print it out with the hole but if I can, I would like to
close it flat.

Thanks @nophead for the suggestion of adding a base. I would see if I can
retain the bust base contour as is.

I will take a look at meshmixer. It looks interesting. But you must
understand this 3D printing thing is a really daunting task for a starting
guy like me. Although my technical background (electronics) helps a bit, it
is still overwhelming with all the choices of software/hardware.

thanks all.
