I will use this thread to post my own requests and use it also to provide supporting material for others.

I am starting with Emmet's head in Foil (3626cp8f.dat)

Finally it turned up!
After countless tries to get the head rolling smoothly on the scanner I have to following two pictures that got pretty well:

   

   

You can see that there is an area on the side where there is no "aluminium foil"

This means the file on PT needs to be reworked...
How have you done the "rolling on scanner"?

I put 5 heads together to get a stable, round stick.

I use a book with a wide back to move the stick of heads, doing it by hand does not give a stable enough speed.

Then I tried several resolutions, but finally I did scan with 400 DPI which gave me a decent speed that I could follow without too many hickups...

...must have looked a bit funny...

Interesting (and funny!) method...

Interesting pictures, but I would rather have some photos of frontside and backside.
These are not useable in LPC. Or, have you seen any good ones on the interweb?
I think I have to recreate the silver pattern. The current part is totally wrong.

I can do some more pictures of the head, will try to upload them before Christmas!

Do you think you, or your son, can find him again? Or has Emmet found an even better disguise?

Emmet turned up! He was where he should have been, in the box labelled "LDRAW"

Here are the additional pictures

Here's a rough sketch of this fairly recent 2015 part, I have not seen anybody working on it, please tell me if you do so.

No work on this part here!
BTW, any news about 20310?

I have a few days off now, I found also some problems in the geometry of my model, so time to finish 20310 :-)

The part does not exist without patterns at the moment.

I uploaded the 18675.dat without patterns and broke it down to a parent without top (s00) and two sub-files for the rim, s01 which is 1/8 without the handle and s02 with half of the handle.

If I would use the same base for s01 and s02 I would need another subfile as s01 needs different edge lines, any opinion?

Origin: I think it should sit at the 0 plane? Or shall it be touching the 0 plane with its top?

I am working on that part now to complement the cover.

Now to the origins. The base part has basically three main origins
The Handle where the Minifig can grab it
The Studs where the it basically should be according to the rules.
The Pivot Point of the book cover.

   

In my opinion the best (for the base) would be the middle of the handle, what do you think?
For the cover still the pivot point, plus a !HELP line to align it. This origin would also help when turning the cover open.

I's indeed put origins in the middle of each part cylinder...

Re: Gerald's PPT > 87745, Pin Joiner with Fin > issue with radius
#16
I started this part actually a (long) while ago, without LDPE. Now I added the finishing touches in LDPE uploaded it again and while reviewing Magnus pointed out that it is not withing the system, i.e. the radius of the full circle center line is 151 LDU, to be precise it is 150,826834 LDU.

Now there is a second Part, 32016, using the same angle, but joined with axles.

I first built the full circle with LDCad's auto-snapping and I ended up with the same discrepancy, a circle with a radius of 150,82.

Using real parts, I got only two of 87745 but enough 32016, a semicircle fits neatly without force into Technic holes spaced 300 LDU (15 holes) apart.

Here's a picture of 87745 and 32016 on top of each other, a perfect match:
   

And here's an overlay of a circle (4-4edge) with a radius of 150 LDU over 32016:
   

You can see the problem there, the vertex of the 1/16th section does not meet the end of the part...

Now what to do? Changing 32016 would break existing models, no good IMHO. I would opt to make 87745 fit the 32016 as both can be interchanged...

What's your opinion?

There is no reason for the circle diameter to be "on system". Distance between middle hole and connector end is exactly 30ldu, angle is exactly 22.5°. This gives a radius of 30/sin(11.25)=153.775 ldu (not 150,82 - and not 150 either). LDCad completely agree as you can see on this snapshot.

And the fact that 8 pieces IRL fit nicely in a 15L beam (300 ldu) is down to the play in the parts. Right?

I think so. 8 pieces need about 17 connexions, each with its own play...

Oh, this Selection Info is really cool stuff!

Yes, the holes are a bit further out from the center.

The radius I calculated is from the center of the 2L axle, respectively the Technic Pin connecting the elements. If I select opposing axles or pins I get a distance of 301.64 LDU

As Magnus wrote, the play of the parts will play a role that it will fit the 300 distance.

So I keep it as is

Thanks for your input!

I just started this part and while doing it I noticed that Part 30565, "Plate, Round Corner 4 x 4" has an issue that a stud is actually intersecting the inner portion of the wall. Should be changed sometime.

If I understand you correctly, it seems that 3 studs intersect the inside curved wall, and part 6003 is also affected the same way.

Exactly, that is the issue with them

It is missing more than stud cavities. (Note that the LDD mesh is also missing them.)

Re: Gerald's PPT > Sandclock (Elves)
#25
Set 41137 from the Elves Sets features a nice new part, a sand-clock.
Unfortunately the number on the part is molded so small, I cannot read it...

The part is pretty nice to do with LDPE with a combination of CSG and Pathtruder tools.

I did the sketch with a hi-res sphere, however on the one hand I think it is too much as the file is now (without subfiling to e.g. a quarter) about 2500 lines long... but on the other hand a smooth look is also not bad...
   

Edit:
PS: I am still wondering how all of the pink sand fits into the bottom sphere ;-)
