| Advice: Shades of Trans.-Blue |
|

I need some advice, please, on specific shades of "transparent blue" to be used in a MOC.
I've attached two images, showing the proposed shades to be used for:
* Building Glass
* Free-Standing Water
* Water Spray (from a water fountain)
In the first version, I'm using color-47 for the water spray. In the second version, I'm instead using color-43. In both versions, I'm using color-41 for the glass windows, and color-293 for the free-standing water in the fountains.
Version 1:
Version 2:
At first, I used color-33 for the free-standing water, but it looked just a bit too dark to me. For now, I'm using color-293 instead.
Any thoughts? Please let me know what you think.
Thanks! ;-)

Just to confirm -- we have not yet had a release this year, correct?
(Curse you, COVID!!!)
Since we now have over a thousand files on the Parts Tracker that have been fully approved, will it be possible to have a release before the year's end? How probable, if one may ask?
Thanks! ;-)

| Fixing rounding errors in primitives |

This is a continuation of this thread. The thread pointed out rounding errors in existing primitives. I have briefly discussed the issue with Chris, and what has to be done in order to fix the issue. He proposed that not only are fixed parts submitted, but also all official parts which have to be updated due to the changes.
Primitives are used very often in the LDraw library, so each change to a primitive will be associated with a large amount of affected files.
I encourage separate posts in this thread for each fixed primitive. Each post should contain:
- What the fix of the primitive is.
- An overview of all parts that use the primitive.
- Proposed fix of all parts that use the primitive and are affected.
This is my workflow. If you want to contribute to this, then I recommend using it as a starting point (and please find ways to optimize it, since this is taking a lot of time)
1) Use a primitive generator and tester like this to find a primitive with rounding errors.
2) Manually verify and document the error.
3) Fix the file (and the 8/ and 48/ version as well if affected)
4) Find files that use the primitive (I use "grep -ir primitive.dat ." since I use Linux tools, such as cygwin)
5) Go through each file and check all the points from lines of type 2, 3, 4 and 5. If any point lies next to a fixed point, then that point has to be updated. I have made a tool to find these points. If you are interested, I can share the tool with you. Right now it is a bit too technical to be released.

Hello, I am brand new here, and only 3 weeks involved in the Lego scene. After building a Lego Crocodile for my grandson, I studied a little bit on possibilities to motorize it. So I found Bricklink Studio, and designed already some train models. And as many other enthousiast I missed some essential parts, as thin rods for instance. Well I know you can buy them at Non Lego suppliers, but I want them also use them as digital parts in Bricklink Studio.
As experienced CAD designer I can make my own parts, and even print them on 3D FDM or Resin printers. I usually use Onshape, a very good and fully free online CAD program for hobbyists. See: https://www.onshape.com/en/products/free
So this week my question was, can I converse my part designs from Onshape to a digital part in Bricklink Studio. And I found Ldraw and stl2dat. In Onshape you can export parts to .STL in txt or binary format. As unit you can choose for mm. My question is, is that correct for a proper conversion?
Some designs:
