Hi there,
Here's one quick way to get the elevation that you want to start the FG
profile for the intersecting road.
Let's call the two alignments A-1 and A-2, and the corresponding profiles
P-1 and P-2. A-1/P-1 represent the main road and A-2/P-2 represent the
intersecting road.
Get the station on A-1 where A-2 starts. You can do this hovering your
crosshairs over the intersection point on your plan view, zooming in a fair
bit, and read the intersection station on A-1 off the tooltip readout. Then
go to your P-1 profile view, and go through a similar process. Hover your
crosshair over the intersection station on your P-1 FG profile, zoom in, and
then read the elevation off the tooltip that pops up. Now knowing the
elevation of the main road FG profile at the intersection point, you can
proceed to laying out your P-2 FG profile.
You may want to change the precision for elevation (and stationing) in your
profile views---C3D seems to default to 2 decimal places, and I'd want at
least 3. If you're using C3D2006, click on the Toolspace "settings" tab,
right-click on the "Profile View" branch of the tree, and click on the "Edit
Feature Settings..." context menu choice. In the Edit Feature Settings
dialog that pops up, scroll down to the "Elevation" branch of the tree,
expand it, and change the "precision" setting to your liking. OK your way
back to your drawing. Your tooltip readout for elevation on the profile
view should now refelct the precision level that you've just set. You
should clearly see that you can adjust the settings for other things,
stationing, for example, in the same "edit feature settings" dialog.
There was a quirk in C3D2005 (at least in the version I have), where the
feature setting for elevation in a profile view was actually controlled by
the elevation setting for "Section View"---the profile view settings seemed
to have zero effect! So if you're using C3D2005, and you're not getting
anywhere by trying adjust the feature settings for profile views, try
adjusting the feature settings for section views.
Hope that this helps.
