Is the 2855 "Technic Turntable Type 1 Top" known to be inaccurate at all?

I originally abandoned my attempt to position a gear to drive this turntable because it looked like what I was attempting was illegal, but now I think my desired position is fine and it's just an inaccurately defined 2855 part.

The enclosed MLCad screenshot shows the simplest example of the problem. All parts are correctly stud-aligned. But I've raised the red gears to highlight the problem. As you can see, the red gears actually cut into the body of the yellow turntable. I've included close-ups of how much the overlap occurs. I also added the grey gears just to show that no such problem exists between the grey and red gears. The problem is only with the turntable.

Can I safely assume that 8 and 24 tooth gears *can* be positioned as shown?

I rendered the attached file using POV-Ray 3.7 and L3P 1.4 beta. Does anyone else also think the transparent glass is not transparent enough? Has anyone noticed this and made alterations to L3P's materials?

I need this for a set of instructions I'm doing. I can do an approximate version that'll be OK, but if someone's already working on them, that'd be hoopy. I don't have the actual part.

Hello, is this part available anywhere? Or could you suggest a similar part to use?

Thanks

Because it was pointed out, we have to agree on a scheme for the different underside variants. I want to discuss this here instead in the part tracker for a specific part:
http://www.ldraw.org/cgi-bin/ptdetail.cg.../3245c.dat

some examples
-> description if there are variants available (stuff in brackets only optional if needed) * for currently used variant

3678a, 772, 3066
-> with Hollow Bottom
-> without (Centre) Bottom Stud(s)*

3794a, 3023, 3245a
-> with Bottom Stud(s)
-> with Bottom Cylinder(s)
-> with Closed Bottom Tube(s)

3678b, 3049a
-> with (Centre) Bottom Tube(s)*
-> with (Centre) Open Bottom Tube(s)

3245b
-> with Inside Axle Holder*
-> with Bottom Axle Holder

4460a (on the right: http://i59.tinypic.com/20rl0r7.jpg )
-> with Bottom Triangular Brackets
-> with Bottom Triangular Inverted Stud(s)

15573 (on the left: http://i59.tinypic.com/20rl0r7.jpg )
-> with Bottom Triangular Based Brackets
-> with Bottom Triangular Based Inverted Stud(s)
-> without Understud*

not created atm (in the middle: http://i59.tinypic.com/20rl0r7.jpg )
-> with Bottom Teeth Brackets
-> with Bottom Teeth Inverted Stud(s)

Imho the last three shouldn't be created if any other version already exists for a specific part. But if one is created one should be picked which is available for the part. So 15573 with "Teeth Brackets" or "Triangular Brackets" would be invalid (at the moment)

All are just suggestions - but I hope we can agree on some wording.

Greetings. :-)

This is my first post on these forums, so hello to you all. I'm about to start studying LDraw, SR 3D Builder, and everything else that I need to learn about, in order to produce custom Lego instructions. I'm keeping my fingers crossed that all these tools are going to work properly under Windows 8.1...

I have a sort of introductory question, as someone who is completely new to all this. I see that there are some very nice rendering tools to create instructions, but is there a particular tool among them that allows configurable old-style rendering? My definition of "old-style rendering" is:

- All studs with black sides regardless of the brick color
- Black pieces rendered in different shades of dark grey depending on the surface angle (like it's done in the official Blacktron and Blacktron II Lego instructions) except for tires where the surface color is pure black with white outlines.

As you can guess, I would like to create instructions that look "authentic" in an old-style kind of way. If not, I guess I'll have to make due without it... Sorry if that has been discussed before, although I did search for it and found nothing.

Thanks in advance for any tips and/or general information on this topic.

I have model A contained within model B contained in model C. How do I determine the position of model A relative to model C's coordinate system? I know that the XYZ coordinates can simply be added. But what about rotation? Thanks!

Good evening all, iam try to create a lego sea kayak I have tried in cad and in brick and struggling to the desired affect or shape . Hope some May gave come across a design or knowledge enough to give he a hand to achieve this I have attached a picture of a sea kayak to give an very rough idea as there are millions of variation . Many thanks in advance

I created a model in LeoCAD, but when I render the instructions using LPub 4.0.0.14 some of the views of the assembled model are hard to follow because of the camera angle. For example the new pieces are hidden behind existing ones. If I could adjust the camera angle, I could solve this, but I have not been able to figure out how to do this.
Are there entries I can make in the dat file or some extra ini file?

Thanks for your help!

I vaguely remember this being possible in LDCad. I have minifig A contained in building model B contained in town model C. How do I move minifig A directly to town model C while retaining its original position and orientation?

Thanks.
