Re: Adding Breaklines to a Surface

I am trying to understand Autodesk's intentions here and can't. In LDD we
used to create ONE base topo drawings, all 2d linework was created during
the FBK import processs, breaklines were created behind the scenes and were
on their own layer SRF-FLT and would generally stay frozen or off. In a
matter of minutes all 2d linework was created and the 3d figure was created.
Civil3d does not appear to have a process for this besides butchering things
up.

It might not be much of an issue if we could use our 3d survey figures, but
since we cannot snap to them or make simple inquiries to them it makes them
highly useless.

If you are talking about a base map to use for printing sheets, I start a
new dwg. Insert the figures, explode them, convert them to 2d polys (modify
tab, expand the Design panel flyout on the ribbon) & flatten (Express Tools
tab). Base map complete.

Figures & feature lines, like all AutoCAD 3d objects do not maintain
linetype patterns when varying z values are assigned to vertices. We still
need a 3d copy for modeling/analysis and a 2d copy for printing.

Not really sure what you're seeing here... For us, Survey Figures are pretty much the same as Feature Lines, and we don't seem to have that problem...

Thanks dei-feif. I wonder what it could be, could it be in the figure
creation from the FBK that is causing this, it's really quite annoying not
being able to snap to end points and such.

All our figures are created via fieldbook. Any ideas?

We're currently creating all of ours via FBK import as well, and we have no problem snapping to the endpoints...

So no, this doesn't sound like any issue I've seen yet. I have no idea what might be causing it.

We can also snap to our figures. Are you trying the snaps in a 2d Wireframe
view? Do you have all the other bells & whistles turned off (Polar, Otrack,
Dyn, etc)?

OK, 2 hours later I finally figured it out. We had all our survey figure
style set to flatten to elevation with the elevation set to 0(evidently this
function doesn't work properly). I ran a sample set of figures from the
Mastering Civil 3d book and very carefully compared the results with ours
and concluded that the only difference was that setting. After I changed
it....voila' all my survey figures work like normal 3d lines again.

But this creates yet another dilema which I have asked about before. How do
you typically deal with the 3d lines in terms of distance inquiries. I do
not want to know the slope distance between I
want to know the horizontal distance. The only way I have found is by using
the inquiry tool and thats not something I want to get in the habit of.

BTW thanks for all the help. There are so many hidden, hard to find
settings we'd be lost w/o this newsgroup and all your help.

If OSNAPZ = 0, Z values are included

If OSNAPZ = 1, Z values are ignored.

I've tried that. It has very odd behavior IMO. If I obtain a distance from
something at 0 elevation to the end of a survey figure at 2000.00 elevation
it does in fact supply me with a 3d distance of 2000.00. If I get the same
distance the other way around by choosing the end of the figure first and
then the point or object with a 0 elevation the distance comes up correct at
2.1 feet. If I obtain the distance between two survey figure end points I
do get a large 3d distance also.

This osnap function sounded like the toggle that I was looking for.
However, it doesn't function properly for me.

I believe this is a bug with the OSNAPZ variable. There have been a few
threads on this topic and i believe that's what we came up with.

If your figures are created from points and most of your distance queries
can be done between points, (I know big 'if's'), perhaps you can insert
points into the dwg at zero & use a node osnap...

Last resort of course is drawing construction plines, dyn, otrack & polar
on.
