Property/Boundary Lines - extruding ?

[MKEllis]

I have a linked CAD file that shows the site boundary in a model and I have used this to generate a property line.

I am now trying to 'extrude' this property line so that it is visible in section views with a height of approx 8m. As the boundary is so close to the structure, and we are using ground beams etc. I would like to to have the property boundary appear as a vertical line in whatever section views we cut through the ground beams so that we can verify that we are not overstepping the site.

Is there a way to 'loft' the line to a given height ?

Thanks

OK I have found a work-around for this - but I'm still having a problem using dimensions with it.

I have used an Inplace Mass, using the Linked Cad Boundary Line, and extruded the form.

I then created a new object category - Form Boundary - and an associated material Boundary - with transparency at 100%, and line set to dash-dot/red. It works quite well in the way that it appears in sections and plans - with one problem - I cannot get dimensions to snap to it.

It is critical that I can place dimensions at various sections to indicated gridlines, capping beams etc. to the boundary line - any idea how I can do this ?

Mass Boundary

Unable to dim to the mass edge (it is not selectable with any dim tool, or able to have a ref-plane snapped to it) - I guess because it is not perpendicular to the section line.

EDITED: The fact that it is not perpendicular is the issue - I got dims working OK with a squared off mass, but rotate it slightly, and it makes the dim invalid.

Any ideas how I can get this dimensioned in section and plan ?

Thanks
