Bionicle 45749 47311

[Max Murtazin]

Hello! I've started learning LDraw recently, and for first parts to be properly made as LDraw ones, I took two ones originally modeled by my friend and converted those to LDraw. Me and him are working together on making library of Bionicle parts 3d models. I want to know, do this two parts fit LDraw standard, or I've missed something? Also, if those are good enough, how can I gan access to uploading parts to part tracker?

Hi, welcome here!

I saw your part 47311 on the Parts Tracker, I will give you some hints, how to improve it and make use of even some more Primitives. That is the hard part when taking over parts from ay other CAD program.

First of all, you should install LDPE, that is the Part-Editor of choice!

Header:
- Missing this line:

0 BFC CERTIFY CCW

In General:
There are no Conditional Lines to soften the rounded surfaces:
-> in LDPE press [ALT + NUMPAD_8) to switch to "Condline Mode"
-> You will see the part turn green and brigt condlins appearing, they are missing on all otehr rounded faces.
-> Those can be generated automagically, but let's do this later (LDPE's Edger Tool)

Also it looks like you mirrored half the part, you can do this too in LDraw making a subfile for half of the part and then use it twice in the main part.

Edges along intersections are missing, e.g. where the Cylinder hits the body.

Intersection of Sphere and Axle
-> Your Spheres are fine, but the intersection with the axle shall be improved, there is a prim for that axlesphe.dat
Instead of:
1 16 0 0 40 12.81 0 0 0 12.81 0 0 0 12.81 8-8sphe.dat
1 16 0 0 19.6311 1 0 0 0 0 1 0 10 0 axle.dat

use:
1 16 0 0 40 12.81 0 0 0 12.81 0 0 0 12.81 8-8sphe.dat
1 16 0 0 40 1 0 0 0 0 1 0 1 0 axlesphe.dat
1 16 0 0 19.6311 1 0 0 0 0 1 0 7.5589 0 axlehol8.dat
1 16 0 0 19.6311 1 0 0 0 0 1 0 7.5589 0 axlehol9.dat
1 16 0 0 19.6311 1 0 0 0 0 1 0 7.5589 0 axlehol2.dat


The special prim will add the necessary edge lines

I am not sure about the placement of the plane that the cylinder meets:
4 16 0 -12.1336 -20.0258 -4.7126 -12.1336 -20.0259 -8.7043 9.2614 -19.9909 0 9.2614 -19.9908
4 16 0 -12.1336 -20.0258 0 9.2614 -19.9908 8.7043 9.2614 -19.9909 4.7126 -12.1336 -20.0259

It is not vertical, I think I would make it vertical to get a proper plane for the axle to  attach to.
The placement is probably at 20 LDU instead of 19.577

The semi-circular parts:
-> No condlines, there, so it will not render nicely, but let's use some prims there:
Check this code, it will add condlines and remove 150 lines. YOu can continue this to the front.
You can use a torus prim to make the curved section. You best use then a 2-4chrd instead of a 2-4ring. THe chrd can intersect with the torus, and you can generate edge lines with the LDPE Tool Intersector.

That'S it for now, I will have a look at the centre peghole, there are some faces overlapping
