Hi,
First off all i hope that i post this in the right subgroup.
I would like to create a new part for the LDRAW library and i do have some
questions
but can't find an answer for it, nor on Lugnet nor on LDRAW.ORG.
1) In witch direction point the X axis
2) In witch direction point the y axis
3) In witch direction point the Z axis
4) In witch direction do we INCREMENT the numbers
5) In witch direction do we DECREMENT the numbers
Can someone explain this?
Perhaps with a 3-D drawing from the 3 axis?
Adding this information to the FAQ in LDRAW.ORG?
6) I'm i right (i could be wrong too) that someone posted an EXCEL file on his
web site
to calculate offsets for the line2,line3 & line4 commands?
I tought it was Steve Bliss, but can find it anymore on his site.
7) I know that parts must be accurate in measure, but how abouth details?
how far do we have to go in detail?
That's all for the moment.
Regards,
Ludo
