Is there anyone who has a solution to "Run through corners" ?

I was a little unclear, this also applies when I save my file as a DGN-file. When I open the DGN-file again, it has lost the "run through corners" setting.

Why does not the settings remain, that is my question.

We constantly receive feedback / comment that the customer wants lines that flow through the entire line, not broken at the insert points / breaking points.

Anyone have any solution? 

Where are these linestyles defined?
Are you working on DWG files, DGN files, or are you working with some other software package altogether? What version of your software are you using?

Are you creating these files with something that isn't MicroStation or AutoCAD, but expecting the drawings to display the same way as they do in your host software?

It's just an 'appearance' problem that some of the authority's technical reviewers are bothered by. And I mostly wonder if anyone has experienced the same problem and if anyone has found a solution to this? Maybe with the help of FME or something else.

At first provide some small example of DWG and DGN where "Run through corners" work or at least some screenshots would be nice because honestly it is hard to understand problem you are dealing with.In MS there is option to shift linestyles which for example is not possible in DWG as linestyles are always centered so for shorter lines you sometimes need a short version of linestyle or create version were first pattern is short and then it is longer.

nd we do get shx-files when we export to dwg, shx-files that we send to our custumers.

If you send SHX files to customers for each DGN you export already means you are doing it wrong because you allow Microstation to automatically generate SHX files from Microstation custom linestyles and not reuse AutoCAD LIN file with standardized SHX.

Here is 3 printscreens of same area, created from same dgn-file, open in MS CONNECT.

Original dgn-fil (3D) 

- Line style works

- Run through corners works

Dwg-file (3D)

- Line styles dosnt show

- Run through corners does not work

Dwg-file (2D)

- Line style works

- Run through corners does not work

We often have to send 3D and 2D dwg-file just to get the line styles to work completely. It is some kind of problem with line styles and 3D files and thats know for authorities and our customers.

But as you can see "run through corners" does not work even in 2D dwg.

There is no such thing as 2D DWG not in way as MS 3D or 2D models. Better use Trueview DWG viewer to check how it looks in ACAD as checking files in Microstation may not show correctly as Microstation can find SHX or RSC files in local Workspace and show linestyles incorrectly.

Where are the corners? I do not see difference except one screenshot is missing linestyles for some reason.

If possible provide examples as DGN and DWG files so we can take a look.

When I mean 2D dwg-file I mean that it is first exported to a 2D dgn-file, then exported to a dwg-file.

If you look at the geen and blue lines, you can se the problem. 

This prinsscreen is a 2D dwg shown i TrueViewer.

And this is the original dgn-file in MS

It means these lines restart at each segment so it seems as if they break at corners. Because DWG has centered linestyles it means the start and end stroke may be shorter and longer depending on segment length so it looks different as the stroke length changes at each vertex. Better try to use Remap table and provide a LIN definition file there so MS doesn't try to convert MS lines to DWG lines.

Please create a DGN with one of these lines with it's linestyle embedded and attach here so I can check what is happening maybe it is true that automatic conversion produces wrong result. Also a working DWG example how it should look. Without that it is hard to help.

OK, let me get this straight.

1. You create a 3D DGN file. All looks correct.
2. You create a 2D DGN file. Do things look correct at this point?
3. You create a 3D DWG from your 3D DGN. Linestyles do not display correctly at all.
4. You create a "2D" DWG from your 2D DGN. Linestyles look correct, except that they break at the corners.

I'll start with 4 first. DWG linestyles do not have the same capability as DGN linestyles. They are not written into nor used by the program in the same way. AutoCAD linestyles will always break at the corners because that's how AutoCAD defines the linestyles. This will happen regardless of using MicroStation or AutoCAD - it is part of the DWG drawing format. There is nothing to be done.

With 3, DWG 3D polylines do not display with a linestyle. See https://forums.autodesk.com/t5/autocad-map-3d-forum/imported-3d-polylines-will-not-change-to-layer-style-line-types/td-p/3456870
However, depending on the version of AutoCAD you have, you may be able to change a setting to make things look better. See https://forums.autodesk.com/t5/civil-3d-forum/3dpoly-line-display/td-p/7850642
If you do not have AutoCAD, you may be out of luck, but you could certainly pass that information on to your client.

For 2, you could just be seeing the difference between the 3D representation of an element and the 2D version. Again, elevation differences can change the way linestyles appear because a 3D line is longer than the 2D representation of it.

I think the biggest problem you have is that you are creating 3D polylines (which will not display with a linestyle at all), and you want DWG files to do something that DWG format simply cannot do. Microstation has no control over what is or isn't possible in DWG format, because Bentley didn't develop the DWG format. It may be helpful to ask about your DWG files over on the AutoDesk website

Thank you very much for a well-written statement regarding DGN, DWG and line styles.

It was just something like this I wanted to hear, from someone with good knowledge and background.

In the future, we will probably also send a DGN file to our customers to demonstrate what the original looks like.

Thanks again for taking the time to respond.

You're welcome. Going back and forth between systems has always been a challenge because there are some things that just do not work the same (or at all!).

Good luck!
