"Front" view not working for georeferenced 2D sections

[Anonymous]

I have a number of georeferenced, vertical cross sections that have been cut through terrain models and saved in DWG format. I now need to review them side-on in TrueView. When the DWG opens it shows the section in plan view (i.e. a single line orientated at whatever angle we cut the section at).

I was hoping that if I clicked "Front" view or some other present view it would take me to a perpendicular view of the cut surface. What actually happens when I click Front is that it seems to take me to some arbitrary xy view angle, which, because the orientation of our sections varies in plan space, often does not match up with the cut section I am trying to view. This means that we either over or underestimate the slope of the terrain we are trying to assess.

Is there some way of setting the view so that I can look at these sections perpendicularly to the cut face?

Dumb Question: isn't a 2D section you can see in plan view mean there is no other 3D view (front or otherwise)?

@pendean not a dumb question, my attempted explanation was pretty long winded. Thanks for your interest!

The section is vertical, but when TrueView opens the DWG in plan it looks like a simple straight line. When you rotate to a side-on view the section detail starts to appear.

The actual issue I am having is that I am cutting sections using 3D mapping packages and trying to export them for 2D slope stability and rockfall analysis software. However the default (plan) view seems to be embedded in the DWG. So when my detailed terrain sections are loaded into these simple 2D packages, they appear as a straight line. I have found however that if I rotate them in TrueView and export as DWF they will then open using whatever view was active when I exported them.

The reason I want to work out how to get an exactly perpendicular view to the cross section is that if I export the section when the view is not quite perpendicular it makes the slope section seem steeper or shallower than it really is - which is not good for slope stability or rockfall modelling!
