Help on authoring x151 (Square Rubber Belt)
#1
Hi there,

I would like to author x151 part.
[Image: x151.jpg]

From what I've found on the tracker there is the x223.dat serie that exists, but in a formed shape.
I want it with no constrain, which is basically a 3 dimensions ring.

From what I've found the belt dimensions are 15mm / 1.6mm.

You can find attached what I've made so far.


Question is, how can I make primitive substitution in ldview not look ugly? I am not able to find primitive rings fullfilling this part dimensions.

Looks like a job for Rings and Cones

I can think of two solutions. Many rings or overlapping rings.

So you are able to measure a floppy rubber band to such a high precision? I'm impressed Wink
Use approximation!
Code:
0 BFC CERTIFY CCW
0 BFC INVERTNEXT
1 16 0 0 -2 0 0 16.7 16.7 0 0 0 4 0 4-4cylo.dat
1 16 0 0 -2 0 0 20.875 20.875 0 0 0 4 0 4-4cylo.dat
1 16 0 0 -2 4.175 0 0 0 0 4.175 0 1 0 4-4ring4.dat
1 16 0 0 2 4.175 0 0 0 0 4.175 0 -1 0 4-4ring4.dat
OK, the band is a bit thicker... by 0.07mm ! I defy you to be able to measure this...

Note also that I measured the rubber belts I have here, there are not two with the exact same size. Average seems to me closer to 15mm (middle of belt)/1.2mm, giving this code:
Code:
0 BFC CERTIFY CCW
0 BFC INVERTNEXT
1 16 0 0 -1.5 0 0 17.25 17.25 0 0 0 3 0 4-4cylo.dat
1 16 0 0 -1.5 0 0 20.125 20.125 0 0 0 3 0 4-4cylo.dat
1 16 0 0 -1.5 2.875 0 0 0 0 2.875 0 1 0 4-4ring6.dat
1 16 0 0 1.5 2.875 0 0 0 0 2.875 0 -1 0 4-4ring6.dat
(edit: the version I initially submited was off in size...)

I haven't measured anything. I've said that I've found some measures. I don't have such a part.

Thanks Philo.
