Adding Breaklines to a Surface

Is there a quick (quick as in 'automatic' or by area or by border) way to
add breaklines to a surface without manually picking each and every one?

Layiso or Isolate Objects to select multiple objects prior to the Add
Breaklines command or

select one, right click & click Select Similar. Right click again & click
Add to Surface as Breakline.

Thanks. Not quite as streamlined as LDD but I guess that will have to do.

(LDT)
1. draw a 3dpoly
2.define as break line
3.build surface
4-(n) {edit breaklines as needed, rebuild surface repeat as required}

(Civil3d)
1.Draw 3dpoly
2.(right click select simalar) add to surface as break line
3-(n).{edit break lines as needed}

Hmm. you sure about that?

One selection & two right clicks in the center of the screen. No TME.

I'm with Joe on this one Mike. 🙂

My workflow in Civil3d, or should I say my anticipated workflow in Civil3d
and my understanding of how things connected was incorrect. Rarely do we
create breaklines that are not created through survey figures. It seems that
all survey figures designated as breaklines are actually breaklines but they
don't show up as breaklines in the prospector tab and they don't appear to
be working properly. I thought I might be missing something and was trying
to add them manually through the breakline tab.

With Figures, I open the survey tab of the toolspace & right click on my
Figure Prefix Database, select Manage Figure Prefix Database & make sure
that the figures I want as breaklines are checked in the Breakline column.

To add them to a surface I right click on the Figures tree in the Survey
toolspace & select Create Breaklines.

If that isn't working, post some data for us to poke around in.

Right. They don't add themselves to a surface. You still have to add them.

Thanks John that was exactly what I was looking for. They certainly didn't
make that option very easy to find.

But, now on to my next issue. Now that the figures are added as breaklines
in the surface how do you typically handle the actual survey figures and the
linework. What I am trying to determine is how to utilize the linework from
the survey figures in the actual topo drawing. As survey figures they seem
to behave very bizzarre (cant snap to them, cant inquiry to them, etc...)

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.

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.

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.
