Finally got round to getting and installing OpenRail Designer in my new organisation. Learning as I go and have dived straight into seeing if we can do simple gauging with Coach Sweep.
I have a Loading Gauge Vehicle template that I have brought into my template library and created the necessary constraints and cant points with superelevation flags. All of this is working well.
I am however having an issue with the curved element that forms the top of the vehicle envelope between the two cantrails. When the coachsweep creates the swept path, this element is faceted/stroked by 4 points.
So instead of having a nice curve, I have a 4 point curve that doesn't sufficiently represent my vehicle.
I have tried the variable in the link below, but I don't think this is for Coach Sweep Curved elements
Circular Component - Stroke value for mesh creation - OpenRoads | OpenSite Wiki - OpenRoads | OpenSite - Bentley Communities
I can go in and remake the template and apply my own stroking, but would like to see if there is a way to get this done without doing this.
Thanks

Yes it is. IIt applies for each arc placed in the template. In the following example I set the variable to 64. Coach height 3m50 (top of arc, side is 3m, tangent lenth=1m).I achieve 2.5mm chord height
Thanks for looking at this jpln
Unfortunately I cannot replicate what you have said.
I have changed the config variable noted to various values (32, 64, 128) and I still get the attached as my coach sweep mesh.
I have checked the config variable name and have remade the curved part of the template in a new template library to see if this was the problem.
Is there any other control or variable that might influence how this tool behaves? Am at a bit of a loss here.
Sorry my misunderstanding. The Coach Swept Path tool does not apply the rounding of circular (stroking). Only corridor does.So in this case you must create the template with the number of points required to accurately describe the curve. Import template from graphic with chord tolerance would be the best here.
In some standards there are some tables Radius,Widening, so that you can easily create the swept path using corridor modelling tools where the circular components are working well.
Thanks jpln
I had thought about curve widening, and I know you can widen on the inside and outside of the curve based on the Widening Tables, however would the length of transition in this case be the bogie centres similar to Virtual Transitions.
Coach Sweep is your new tool to provide a mesh for a swept path, so it seems a shame to use corridor modelling when this exists. Could I suggest an enhancement to the modelling tool that enables the stroking of curves with a variable similar to to that for corridors? Or could the same variable be used to control the Coach Sweep stroking that is used for the Corridor stroking
ThanksAl
The curve widening table allows to apply distance from first/last point of transition to start/end variation in the straight or arc.
May I suggest to log a service request for an enhancement. Easier to track against your company and for the following.
