Alternate model of 8868 set.

Known errors: none.
Done with LDCad 1.6 alpha 4
Random notes...
- Max's work on an old model (http://forums.ldraw.org/thread-21839.html) made me want to try an old studded Technic set. What better one than this model - with a pneumatic state machine!
- Old building instructions were definitely not for the faint hearted - only 24 pages for this model! The average quality of the scan doesn't help...
- Pneumatic tubing remains tedious...
- Some angles in the skip are only (close) approximations - I think it actually relies on part flexibility.

As far as I can remember from the real world model you are right, it relies on part flexibility.
Anyway - this reminds me, that I need some spare parts, cause time has eaten the plastic softener of some parts...

thank you for building and contributing this model! I searched for the main model without luck. If it's not done yet, I would appreciate to jump in and try my best (with a bit of fear about all those pneumatic hoses which I installed many times in reality so many years ago).
Best regards
Stefan

...step 23 of 32 done...
I just added a single rubber band, and the file size grew from 30 to 200 kb for the generated segments... I know, this is not a "big file", but I would like to ask if there are hints for rubber bands like for hoses (see Philippe's hints for the 8854 Power Crane) - so I would play with them. I can't figure out the correct part-replacement and the options to change... 
RE: 8868 - Air Tech Claw Rig - Dump Truck - Philippe Hurbain - 2020-02-09
The templates I use for compatibility with Studio are LQ type and should provide smaller files. Drawback, the band is thinner, making it thicker would require to add a scaled cylinder element in the library (and in Studio custom elements)...
Attached these templates! (To be put in C:\Users\<your user name>\AppData\Roaming\LDCad\templates\path)
RE: 8868 - Air Tech Claw Rig - Dump Truck - Stefan Frenz - 2020-02-09
This is awesome!
The required space for the rubber band is reduced from 170 kb to 14 kb.

With a scaled 4-4cyli2.dat (done with text editor) as donPart included in the mpd, the rubber has correct thickness and the required file space is very very tiny.

...May I ask: is there a LQ alternative for the 9V cable (path\elecCable2Brick), too?
