Hi,I'm getting tied in knots & v exasperated. Problem is with the gap between locomotive & tender.Out of the box I'd need to find a fireman willing to make Olympic standard jumps between each shovel of coal. <P> <P> <P> I've tried changing length, inertia tension & bounding box values.I get closest with bounding box - it's the only value with asymmetry. I get close but it won't close up as much as I want. If I change the length value it crops fore & aft values such that it won't allow double-heading - the buffers overlap. Altering the tender values also caused buffers to overlap. The tender is more or less common to all 3 locos. I've tried moving the bounding value for the 4-6-0. <P> <P> <P> Strangely I can get close with the 4-4-0s but the 4-6-0 #334 won't close up.The measured lengths from TSM are spot-on. I've tried the values without the cab roof & tender overhang. I've brought the bounding box in by about 1.5 metres.Can anyone solve this problem?In anticipation. Richard Osborne
RE: bounding box problems - I need jumping firemen
yup I can. Its not the bounding box its the position of the pivot center of the main part. make sure the main part pivot center is centered between the pilot bar and the cab back, excluding the cab roof overhang. Then make the bounding box in a normal way. On the tender center the main pivot excluding the drawbar. When you put the two parts together they will match just right. hope that helps

John,You're spot on! I'd built the locos with the datum at the driven wheel - obviously thinking of models.It should have dawned on me that a 4-4-0 is more asymmetrical than an 0-6-0, a 4-6-0 is more asymmetrical than a 4-4-0.I've moved the whole model 1.7 metres & reset the datum point. It now sits exactly as it should.Thanks for the advice - something else to put into the experience bank.BTW I've got a couple of your locos in my stable.Good things these forums!regards Richard Osborne
RE: bounding box problems - I need jumping firemen
So THAT'S how you figure out the center of origin! I have been fighting with my models for the last few months trying to figure that out!For some reason, I always thought the center of origin had to physically be in the center of your model. I guess that is not the case??Now I want to run home from work and try it out! Brian.
