Wheels wont go round.

Hi,Paul,Thanks for the info,on the wheels,i just could not work out,why,the wheels would not go round,i thought it was something that i did wrong,i will give your engineer a try.
Many thanks,Howard.

Hi,I have just upgraded to 3DC pro,and i have followed the tutorial,by Ian Morgan,how to build a wagon,with 3DC pro,and i have followed the tutorial,step by step,and put the wagon in the simulator,and all is ok,apart from the wheels wont go round,i have used the normalize groups,used the snap to grid,and the wagon is facing the right way,for export to the simulator,the only difference in the last part of the tutorial is,Ian put the wagon in the sim,manualy,and i have used the train sim wizard.
I would be very gratefull,if someone could help me with this problem,it is the first attempt,that i have have done,at making rolling stock.
Many thanks,Howard.

For wagon wheels, the naming of the groups is critical.

The main group should contain the bogie1 group
The bogie1 group should contain the 2 axles in wheel11 and wheel12 groups, the group pivot point for these must be in the centre of the axle (X value not important)

For a quick example, run my engineer plugin and select the 4 wheel wagon from the panel on the right and press start.
