Hi, I’m currently attempting to place rail sleepers/ties along a rail alignment with CANT applied using the AlignmentExtensions.GetCantInfoAtStation node. but and struggling with orientating the block to follow the cant rotation. Any ideas please?
Hi @aa047 ,
I’m not a rail expert, but could you get coordinate systems along the profile at the desired sleeper locations and then rotate them?
Thank you @mzjensen that works!,
I actually manged to get it to work about 5 mins before you posted via a different node.
I found Vector.Rotate worked a treat too.
Multiple ways to get there glad it works!
Thank you for posting your Cant Example.dyn script.
I have added a basic corridor to your Cant Example.dwg using the standard “RailSingleTrackCANT_w_ExtraLayers” subassembly from the rail toolpalette to check whether the ties are placed as expected.
It appears however that the ties do not follow the same cant as the corridor. See below.
Do you perhaps have any ideas what i may be doing wrong or what the reason might be?
Hi @mzjensen, thanks for this graph, i have tried using it and i am running into the following error;
The block are placed along the alignment, however, there are gaps in-between, I have tried changing to the geometry scaling to “Extra Large” and made sure that the blocks are uniformly scaled. Any ideas on what I can do?
PS: the alignment is fully continuous and the spacing set on the graph is 0.75m
As a rule-of-thumb, leave the geometry scaling set to “Medium”. There are other examples on the forum for why that is the case.
Regarding the warning, I’ve been able to solve this in the past by changing the block definition to not be scaled uniformly. It’s not what the warning says, but it seems to work.
