Removed an unneeded line.
Could somebody tell me where should the origin be? Currently it's on the front tip of the pump, which I don't think is too right...

Good attempt, but a few things to mention.
- I think you have only modelled the outer surface and not the inner surface. You have to model also the inner surface!
- There is no BFC statement, but it has to be there. A '0 BFC NOCERTIFY' would be ok for your first submission.
- You use /48 primitive and normal primitives, but I can not see the reason why you mixed it.
- There is a 4-4cyl.dat missing at the rear of the part (insert) and an 4-4edge.dat around the 4-4disc.dat.
If you need any more assistance, please feel free to contact me. Just the BFC is not easy to understand, but not very difficult to put into the part.

Added BFC NOCERTIFY

I had to use the 48 primitives, as there's no such thing as 4-4ring3.dat or 4-4con2.dat in the normal primitives. The normal primitives just weren't thick enough!

As for the surfaces, I think the interior of the part looks like the real version of it. I looked inside, twisted it (it's soft plastic) and it's transparent, it looks pretty much the same. I think there's no surface issue.

There's not supposed to be a 4-4cyl.dat, as the edge serves as the edge for the cone. There's no thing I'd classify as cylinder surface at the end of the real part in my opinion. As for the disc, there is, it wass just one line off. That's fixed now.

"Added BFC NOCERTIFY". It needs to be added to subpart too. About BFC, see http://www.ldraw.org/Article415.html - and see below!

"there's no such thing as 4-4ring3.dat or 4-4con2.dat in the normal primitives". For historical reasons, small size ring primitives don't follow standard naming shape. These are called ring<x>.dat. But a 4-4ring3 was submitted recently (http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=p/4-4ring3.dat) to correct this situation. And 4-4con2.dat does exist!

"As for the surfaces, I think the interior of the part looks like the real version of it." The problem is that a Ldraw surface has no thickness, so there should be another surface inside your pump to materialize its thickness (0.5 ldu?). This can be related to BFC, where you consider LDraw surface as beeing single sided. To see that, use Red/Green BFC mode of LDView (there must be a BFC CERTIFY statement in the part you look at). If you see a surface from the wrong side it appears red, otherwise it is green. A completed part should appear completely green. If not, there is something wrong...
- For a triangle/quad, inverse its winding ("swap" button in MLCad)
- For a flat primitive, mirror it in the flat direction
- For a 3D primitive (eg. cylinder seen from inside) add a BFC INVERTNEXT statement at the line before.

BFC might be seen as a constraint, but actually I use it as a help while building parts, since it ease seeing distinction between inside and outside.

"There's not supposed to be a 4-4cyl.dat" Yes it does, see http://www.brickshelf.com/gallery/Philo/Misc/618101.png. 1 shows the missing cylinder, 2 the missing edge. Or (I don't have the part!) the disc should come flush with the cone, but it does not here, see the red line revealed by BFC view meaning we see "inside" of the part.

Other issues:
http://www.brickshelf.com/gallery/Philo/Misc/618102.png
- one ring3 is bleeding inside (4)
- 4-4edge floating inside (wrong diameter) (5)
- imho origin should be centered (6)

http://www.brickshelf.com/gallery/Philo/Misc/618103.png
- perhaps an edge is missing there (7), or at least a conditional line.
- Origin would be nice on the sitting plane of the part, flush with the mating part surface. I guess (again, don't have the part) it is in (9) instead of (8) plane.

Added BFC CCW to both part and subpart.
Ceased use of 48-primitives
Understood the meaning of surfaces and fixed the ones in the part.
Added cylinders to subpart and other places, but I still think that there shouldn't be one in the end, as I think that the cone already is the surface neede there.
Fixed one ring3 bleeding inside.
Somewhat fixed 4-4edges floating inside.
Origin centered (I thought I fixed that before... obviously I didn't.) and moved to the mating spot.
Added an edgeline to the border of the cone.

Looks much better now, but I stated previously BFC is difficult. If I look with LDView at this part I see green surfaces and red surfaces. Red surfaces can't be seen in real life because it is the backside of the outer surface that you can see. If you look into the pump all surfaces are red. That means that the material you have used do not have a thickness! But in true life material has a thickness. At this part it may be 1 mm, that I would round to 2 LDU. So what you need to do now is to model the inner surfaces with a distance to the outer surface by 2 LDU. Then you get a part that shows at any view only green surfaces. Then it is perfectly BFC'ed.

Much, much better now. I think, now you know what is meant by BFC. But:
1) The BFC Statement is gone?
2) 4-4edge.dat line 26, 37, 38 has wrong dimensions. It has be the the same as the cylinder in line 20.
3) The 4-4edge.dat between the inner cylinder and the cone is missing.
4) Line 25 4-4con9.dat does not fit to cylinder size so there is a gap.
5) Lines with '0 BFC CERTIFY INVERTNEXT' are not allowed in official parts. This is a bug in MLCad. If you use Windows as OS I would give DATHeader (http://home.arcor.de/mikeheide/db86.html#ch641) a try because that prog cares about some issues to have goods parts for the PT.

There might be more errors, but I like you to check yourself so you get a better understanding of what happens.

I had just found an old thread (http://news.lugnet.com/cad/?n=13930) how to review files. I think this technique would also be a good idea for self controlling before submitting a part. It is much more easier to locate failures.

Did some finetuning with the cylinder sizes, re-added the BFC CERTIFY CCW and changed all BFC CERTIFY INVERTNEXT:s to BFC INVERTNEXT:s.

The file parts/61810s01.dat got created by accident by me forgetting to change the radiobutton, however... should I email the admins about this, or what should I do?

I have now take my own part and measured:
1) length over all 100 LDU
2) total pin length 35 LDU
3) outer diameter of pump section 60 LDU
4) diameter of grooves of pump section 50 LDU
5) cone section of pin 10 LDU starts with diameter 26 LDU
6) straight section of pin 5 LDU diameter 29 LDU
7) ring section of pin 4 LDU diameter 33 LDU
8) straight section of pin 16 LDU diameter 28 LDU
9) plane surface of pump diameter 44 LDU
10) disc at the end of the pump section diameter 44 LDU
11) Inner diameter of pin section 22 LDU and there is no cone inside.

I think some of these dimensions are not in your model.
Happy coding!

Yes, please email the admins to delete the file that is wrong uploaded. I always went to the detail page of that part and put the url of that page into the email, so the admin can easily jump to that page and can react.
It seems that we have nearly same time made our submissions, so I did not checked yet your last submission. Please have a look into the dimensions I have measured and adjust as needed. I will have a look into your next submission.

Many inaccuracies causing gaps and floating things.
- Ring at line 41 is not needed
- Edge at line 46 should have R=19.7
- edge and cylinder at lines 24/28 should have R=11.25 instead of 11
- edges at lines 37/38 should have R=15 instead of 15.4
- edge at line 31 should have R=17 (it is oval, 17/17.1)

Precision is of paramount importance in parts modelling !!!

Ah, nostalgia... too bad to kill my first certify vote, but I did quite some cleanup and improvement to this part:
- 48:d airtank, mouth left lo-res
- Inlined subpart
- Fixed airtank front cones; altered matrices so that the cones now meet smoothly
- Ordered up better
- Ran through DATHeader and removed the gigantic !HISTORY block

Added missing edge, and removed half of the condlines. They were edgelining the notch between those two cones that I just ground out.

Speaking of the anniversary, you can only imagine how much I'd want to create the other two parts. But the arrow has a geometry I can't figure out how to get, and the base itself is so darn bizarre...

I would like to question the origin choice.
It currently is "somewhere at the cylindrical section".
I suggest to move it up or down a little to at least
be at one of the cylinder ends,
but even better IMHO would be to move it to the bottom
or to the top.

It is a single mold, transparent rubbery part. Nice to see that this was fixed, I've been busy.

Maybe someday I can finish what I started 4 years ago and model the complete Nynrah ghostblaster...
