Hi guys,
I'm new to LDraw and recently I created my own parts in LDraw.
I would like to reuse the small part created in another larger part but I cannot use the small part as a sub-part, should I upload the sub-part to library or just put it in the p file(but seems like it cannot be recognized if I only put the sub-part in p file)?
Do you know what I mean? What should I do, any helps please?

| Regarding rendering of parts |

I am trying to write a renderer and so trying to understand the document http://www.ldraw.org/article/415.html.
My first question is does a reverse matrix (determinant < 0) perform a mirroring on the part as I have seen in some places or just changes the winding as the document suggests. I wish the pseudocode at the bottom of the document also included the negative determinant part of the drawing process.
Also regarding rendering. If I open the subpart box5.dat in ldview the backfacing polygons are not rendered. But If I create a file sample.dat and in it I put the line "1 16 0 0 0 1 0 0 0 1 0 0 0 1 box5.dat" and open sample.dat in ldview then the backfacing polygons are rendered. From reading the above document I do not understand why that is the case.
Thank you for any help.
