import sdf as barrier for fence/guard rail extends beyond vertices

[Riyaz.Hussain]

I am importing polygon or lines in infraworks to create fence - but it extends beyond the vertices.

Please provide the solution.

Infraworks 2020

Good day, I have similar situation in all Cases with cutting model (using boarders in Model's property - draw or select polygon) or importing another contours (sdf, shp ...) - and I must delete points in object that goes farher that surface. 
I think - it's global problem of IW (because IW can't add to object's geometry new point (as f.e. work "broader" = structural line in Civil 3D's Surfaces)) 

Other visible problem - when boarder going through building - and it was no cut.
May be there is command to Java - delete parts of problems objects automatically...

I'm assuming that you are using the "Guard Rail Straight" model that comes with InfraWorks. That 3D model is 3 meters long, so if the length of your imported polygon/line is not divisible by 3, then it will not line up. It is not going to trim the ends and corners; it will only place an object at discrete intervals. If you use a Barrier style instead of a 3D Model, then you have more control.

I've solved this one before - I exported the model and resized it, before reimporting it as a style, or alternatively divided my line section up neatly into 3m sections. One could also dynamically scale the x dimension of the model based on the length difference between the vertices expressed as an attribute.

Thanks Dear - All is well with barriers and a style with it.
