How can I search for my (sub)parts that contain rect-primitives on the tracker?

I would like to have part 5188 please

I've been struggling with getting parts 2677 and 2678 to work together (and with other monorail parts) in Stud.IO for a couple of days now, and after thinking something might be wrong with them, I eventually discovered something wrong with part 2772c01 (Monorail Track Monoswitch (2772c02 / 2774)) instead. After examining this part closely in PartDesigner, I realized that the anti-studs at the bottom are actually misaligned. It turns out that part 2774 is sitting slightly too high above part 2772c02 in that assembly. This means that any monorail that includes the Monoswitch is bound to be misaligned, even if all connections along the monorail are perfect.

I can produce a corrected 2772c01, but it's probably better if someone else does it who has more experience with .dat files and can ensure that the resulting part would be perfectly aligned.

Hello! I'm looking to have Item No: 60899, the Bionicle Av-Matoran Leg Section with Ball Joint and Ball Socket added, currently only the Bionicle Arm Av-Matoran with Ball Joint and Ball Socket exists in Stud.io and I would love to see both added.

If relevant information, it comes in the following colours:
Black
Dark Blue
Dark Bluish Gray
Dark Green
Lime
Orange
White

Thats all! Thank you all for your hardwork!! 

I can not seem to find this part in the studio catalog, and I am struggling to locate it elsewhere:

Does anyone have the part file for this?

Hi Team!

Just updated my MLCad v3.51 with a few of the latest parts updates (from Parts Update 2025-02 onwards)

I did it the way i normally do:
download zip file
extract to folder
copy parts, s, textures, p, 48, 8 to their relevant folders
run mklist
scan parts in MLCad

This has always served me well in the past.
However this time, there are lots of vacant spots in the part selection menu on the left.
Worse still, every file i load (ldr or mpd) fails to show some of the builds.

I know they are there, because i can make partslists from the file, but i can't view, or select them.
If i select all, then delete, then UNDO, the image shows. But saving this over the old file changes nothing.

Also, if i start a new file by dragging visible parts into the editing windows then all is good, but as soon as i drag one of the NON-visible parts, and refresh view, all the parts disappear.
Same as above, they are still "there" when making a partslist, but i can no longer view or select anything.

I've found this also seems to happen if i download a complete copy of ALL of the parts.

Is it something i'm doing wrong, or am i doomed to using old parts forever?

Thanks in advance.

I need something narrow between a cylinder and custom quads. The sweep is 5-48.

Is it better to create a 5-48 aring or ering?

The duplo skateboard BL 2319c01 has two numbers on it; 2319 and 346M2. Is the other number an assembly number?

I'm working on the duplo flower with 5 Leaves and Top Stud 84195. I've fixed most of the issues with the original mesh, but...
I don't know if I should submit it as one part or subdivide it into 5 (10) repeatable subparts. One of the challenges is rotation. The original mesh is not aligned with any axis (see top view in picture), so it would be very difficult to create clean symmetrical breaks (normally I'd use the mirroring over an axis). The angle of rotation between parts would be 72 degrees, which would require six decimals in the transformation matrix. Given these challenges, would it be acceptable to "ignore" the 5-fold symmetry and just not subfile at all?
