Please help, the edges of the new parts are not smooth

Here is your part.

Copy the two files in your LGEO library.

Don't forget to add this in your ldraw.xml file :
        <Element>   
            <LDrawFilename>888001.dat</LDrawFilename>
            <POVName>lg_888001</POVName>
            <POVName Alternate="Clear">lg_888001_clear</POVName>
            <Dependency>LGDefs</Dependency>
            <POVFilename>lg_888001.inc</POVFilename>
            <MatrixRef>LGEOTransform</MatrixRef>
        </Element>

BTW, I will not do non-LEGO parts anymore, I did that one because I told you so, but that's it.

Thank you, really very grateful for your help!
