For example I need to create a TBM tunnel lining which consists of many rings and each rings has 7 segments these segments can not be created by model in place and when I create them by mass I cannot pu rebars on it or if I use sweep or extrusion I can not create the exact dimensi...
and how can i bring this spline back to the plane parallel to that red surface (it should still touch the line in the middle of square, so it should rotate at the point where it touches that line) after this , i will sweep that square along the spline using it as a path, and...
Is the 3Dpline in the first or second layer the intended sweep path? or, are you trying to loft between polylines? It appears from the "test" layer that you are indeed creating the solid but the left (back) face is the one that's not turning out as expected...
I would like to use these 3d polylines as path for placing families in Revit. Those must be also correctly georeferenced. Since Revit does not recognize 3d polylines as path for Sweep or Blend (the path must be a spline in revit!!), I have to consider an another workaround. ...
