Ditch closing object/block

szuri62SSR — Mon, 22 Aug 2022 14:02:50 GMT

How can i put a specific block to the end of ditches ?

I tried with COGO point but I only managed to get points (from the ditch profile height) that show up on the alignment.

That's a tough one. Using a block would be difficult because different ditches may have different widths at the ends. I have yet to find a way that allows the ends to be nice and cleanly built with the ditch corridor (assuming you're using corridors).

On a project with a ton of ditches, I created a special display Code Set Style for the ditches so the ditches can be inserted and displayed in deliverables and always reflect the model. And the ends (arcs, polylines) just have to be managed by hand. Still a lot less work than managing ALL the ditch lines.

@jameshitt gave the big hint here, all that needs to be done is adding a featureline that gets your data set looking sweet. I'm sure there are many ways to achieve the goal, but simply adding a featureline can handle the box situation.

I tried the feature lines, but it gives it back with more breaking points due to the corridor settings, the main problem is that we draw the profile of the ditch as a continous line so we have to delete the parts we don't need manually.

I managed to get the starting and end stations of the ditches as alignment lables, can I make some kind of expression to offset the label (block/line) to the specific feature line?
