I have been looking at a bunch of forums trying to locate a solution to my problem, but have not found what I am looking for. So I am asking for some advice.
I have created a Horizontal alignment from cogo points that have and XYZ location. When I regress the alignment, it automatically attaches to a Z elevation of 0. Then I create the vertical alignment off of the horizontal alignment points. When I view it, it has an attached value for Z, but it still shows it at on an elevation of 0. When I go and create the corridor, I can only see my proposed alignment from a plan view, but when I go to look at it on a skew, it still is at an elevation of 0. I know that I can view it as a 3D alignment and it puts it to the elevation attached to the vertical alignment, but then it shows each segment of the line between each cogo point, I need it to show the tangent, spiral and curve. Is there something I am doing wrong, or something that I need to be doing to have my proposed alignment at the correct elevation? When I run the corridor modeler, my template aligns to the correct vertical height, just not the proposed alignment visible line.
I am using micro station V8i SS2 with Rail track. It is the same a inroads, to an extent.

Horizontal Geometry and Vertical Geometry do not share the same 3D space while maintaining geometrical properties. InRoads "displays" Horizontal Geometry with tangents, curves, spirals in the horizontal plan XY. Yes the points can have elevation values but elements between geometry points are planer.
Vertical Geometry is likewise "displayed" in a horizontal plan XY, with elevation represented on the Y axis and the X axis represents linear stations.
The 3D alignment is as you have seen an incrementally stroked representation of the Horizontal and Vertical geometry. There is no current method (that I am aware of) to display horizontal and vertical geometry in a 3D geometrical space, while maintaining both horizontal and vertical geometric integrity.
The Horizontal Curve is radial and the Vertical curve is parabolic (roadway). Not sure if one single element can be drawn with a radii XY and parabolic Z. Even the vertical geometry drawn in profiles is an incrementally stroked curve. I am relatively sure when vertical geometry is drawn 1:1 it could be a true parabolic element but often vertical geometry is vertical exaggerated when displayed in profile.
