I try meshmaker.inc
Problem. Splines aren't closed
But, in konsole:
File "Empty.pov" line 332: Parse Error: Spline must have at least one entry.
Fatal error in parser: Cannot parse input.
Render failed.

Hi,
In the file you supplied the splines are missing the closing }

Is that the problem?

Hi!
Thank you!
New problem!
At the bottom of a vessel triangles are visible

Does the surface have zero thickness or do you have coincident surfaces?

You have sevral messages about normalizing zero-length (null) vectors. 
The results are undefined and may explain your artefacts.

Try cutting your object in half, parallel to it's axis, using a textured 
plane or box, like pigment{rgb <0,1,0>}. It may reveal some problem.

zero thickness - no
coincident surfaces?
Each end of a curve is on other party of an axis.
But how differently to make a bottom closed?
