Subassembly CANT

[dar.lombardi]

Hi,

I have subassembly of rail track. It is capable of responding to rail cant. I have to add to it the shape of the train.

In subassembly composer I built the shape of the train with rail track .

How do I constrain the shape of the train to the rail cant?

Something like the attached .pkt file (unzip to use) should put you in the correct direction I think. Note that I did not test it in Civil 3D since I didn't have any files handy with Cant to test with so you may want to do that first before adjusting dimensions. 

You will need to fix the dimensions defined by all the even numbered auxiliary points in the "Auxiliary Point Train". The even numbers define the left side of the train shape and the odd numbers provide the right side in mirror image to the left. The "Auxiliary Point Train" does not use the Cant values. Then the points use the x and y lengths of each corresponding auxiliary link and apply the angle defined by the cant using a center pivot.

Thanks. Very useful!
