contours and breaklines

I'd tell you what you're doing wrong, but I noticed that you are writing articles for "THE DARK SIDE" - TRAITOR!!!!!

😉

just kidding! I did enjoy your article.

As for as your x-ing breaklines/ Carlson problem-

consider buying Microstation and Geopak We never experience any problems...........

Have you tried manually adding the breaklines via the triangulation surface manager? Also, is the bottom breakline directly under the top one? If so, I've had luck offsetting the bottom one by 0.05 or so.

This happened to me once and In think I just started over with a new surface and it worked. So it was probably something stupid I did and didn't do it again the second time.

Make sure you've got all your boxes checked correctly and if all else fails, you could call tech support;-)

Thanks File... There is no dark side 😉

I did try that Big, and my solution was to do two surfaces and contour separately...
The steep bank is one surface and everything outside the bank another...

Oh, and no, the breaklines are separated by at least 2'

I know nothing of Carlson, but LDD has a command called "flip faces" or something similar that changes selected tin lines. This almost always corrects a contour/breakline conflict. Perhaps Carlson has a similar command?

I didn't know you were a comedian. 🙂

This may sound stupid, but do you have an elevation on your breaklines?

I did go back and draw them as 3D polylines and then added them as a breaklines.

That's happened to me. It just isn't seeing the breaklines and I could only get it to work by deleting the breaks and remaking them. Took about 10 minutes to recreate them and probably 2 hours trying to fix them first.

Lets come out of left field and try some odd stuff. Check underSettings/carlson settings/general settings and be sure "Link points with CRD file" and "Link linework with points" are both checked. Then go to Triangulate and Surface/Selection and see what you have checked in that window.
Get it set the way you want and rebuild your surface.
Maybe, Maybe not?
Plus you can switch tin edges or add breaklines to get the results you want. (If all else fails. NONE of the contour pacs I have ever used get all the breaklines right the first run through. I've always had to tweak them a bunch.)

In the software I use, after tagging the hard break lines, there is also a box in the triangulate and contour window that finds point on the break lines.

I wonder if you have such an option and if that would make the software interpolate the points needed to not cross the break line.

I don't see that option under settings, anywhere!

I haven't got time to look at it right now, but if you send me the files I can take a look at it this evening.

email in profile is good.

we've been trained in all the right buzz-words-

there are no "problems"

maybe some "Challenges"

maybe some "issues"

but no "Problems".....

That's right. In software development we call those "undocumented features" 😉

It's usually something simple... perhaps a 2D polyline was used rather than a 3D polyline. Another possibility is the infrequently visited Selection options of Triangulate and Contour.

If you still have the drawing or data set that exhibited the behaviour, feel free to send it to me and I'll check it out for you.
