Hello
sorry my english is bad ;(
I have a bug with import  file Thingiverse.
If I take everything one file, everything is ok, and I can do a .stl
http://forum.openscad.org/file/n14954/bug1.jpg
but if I add something I have an error: ERROR: error in
CGAL_Nef_polyhedron3 CGAL (): CGAL ERROR: assertion violation! Expr: e->
incident_sface () = SFace_const_handle () File:
/opt/mxe/usr/x86_64-w64-mingw32.static/include/CGAL/Nef_S2/SM_const_decorator.h
Line: 326
http://forum.openscad.org/file/n14954/bug3.jpg
code :
module woman (){
import ("sunbathingnude.STL");

    }
    
scale([7,7,7]) woman ();
    translate ([-40,-30,20]) 
    rotate ([-60,0,0])
   cylinder  (d=23,h=100,$fn=100);

This is not code or file because if I add something even without touching
the import file I have this error.
I tried with a dozen files thingverse and I still have the same error line
326

Thanks for your help

Hi. You may try to repair the .stl file first, with meshlab or acessing

The problem is not repair the stl file , because the .stl only is correct ,
no problem
but when i make other objet with the .stl cube or cylinder or other , i have
this error.

This sounds like the following FAQ entry:https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/FAQ#Why_is_my_imported_STL_file_only_showing_up_with_F5_but_not_F6.3F

I do not know if I understood OpenSCAD does not accept nude?

but with 90% of import STL files I have this error.
nude or otherwise, here it was just an example

thank you for your replies

yes i understand what you mean
but the problem is that the only stl file works very well, I can do F6
So it is good and fixed
but if I add a line or two of code into OpenSCAD, to a far away from the
cylinder stl file, I get an error when I do not change the file stl

sorry my English is too bad for me to express myself clearly
