Hello,

Among the primitives, there is the primitive n-fchrd.dat. This primitive is well suited for creating a transition to, for example, an enclosing circle. Unfortunately, the starting point of the circle segment is always at 0°. Sometimes it would be useful if this starting point were at 22.5°, for example. The circle segment would then go from 22.5° to 67.5°. In the high-resolution version, it would be 7.5° or a multiple thereof.

Rotation that is not equal to a step size of 90° results in rounding errors that can lead to visual errors.

Furthermore, a similar primitive would be useful, forming a circle segment from, for example, 22.5° to -22.5°. The center point of the circle segment would then be at 0°.

My question is whether it would be possible to introduce such primitives.

Best regards,

Manfred

Hello,

I would like to create a new primitive (4-4ring179.dat).
To do this, I looked at the primitive 4-4ring18.dat. I noticed that the values of the individual points are, in my opinion, incorrect.
A quarter circle consists of four circle segments. The angle of each piece of the quarter circle is 22.5°.
The first line in the primitive file looks like this:

4 16 19 0 0 17.5541 0 7.2713 16.6302 0 6.8886 18 0 0

19 0 0 is the point at the bottom right of the first circular arc segment. For the second point counterclockwise, the following applies:

x = cos(22.5°) * 19 ~ 0.923879 * 19 ~ 17.55371111 -> 17.5537
y = sin(22.5°) * 19 ~ 0.382683 * 19 ~ 7.27098521 -> 7.2709

These values differ from the values in the file.
The deviation is very small, but it is there.


My question is: is the value in the file correct and I have made a mistake in my thinking? If so, what is it? 

Best regards,

Manfred

Hello, I have to deal with this part on Rebrickable, and I have a problem.

On BL and here, the part is called : [...]with Dark Tan Crescent Pattern, whereas its called [...]with Reddish Brown Crescent Print.

At first I thaught there was 2 different parts, one tan and one brown and that I encountered a mapping issue. But this part seems to have been used in one set only. and the picture on BL show a reddish brow cressent and not a dark tan one, like the LEGO element render.

Is it because dark tan printed on black looks like reddish brown ? Or Is there an error somewhere ?

Hello

The part in question is variant of 98138 (Tile, Round 1 x 1) with TIE Fighter cockpit print. IIRC Trans-Clear.

I'd greatly appreciate if it could be added <3

Hello!

Part 4592 currently features mismatch between dome and cylinder parts. 
   
As seen in attachment, this leads to holes in geometry. I'd greatly appreciate if it could be fixed. <3

New in this release:
With this release it is possible to get colour values with a function call. This can be useful when using the OpenScad Customiser.

Important Notice:
Both the installation method and usage of this library has changed. Please read the updated installation and usage sections in the README.

We here at LDraw.org humble ask the community to contribute to the continuing costs of running LDraw.org.

I will be ending the fundraiser as soon as the goal is reached.

Thanks again for helping.

I am in the process of making a bionicle Moc when I realized the parts in which I had planned to use are not in bricklink studio, would it be possible to have them made into L draw’s database so I can add them into my custom parts in stud.io? The rifle shell is of most importance for me, it’s excellent for robot arms and weapons.

Part 98138pb0.dat was never converted to have an ering like other similar parts were so it looks bad in high res.

The link here: https://wiki.ldraw.org/index.php?title=G...ed_-_Linux says to download from here: https://www.ldraw.org/parts/latest-parts.html

However that last link is a 404.
