Custom 3D line styles from V8i don't work under CONNECT

I believe the following Defect reported by another user may be related to this issue you're reporting.

Defect 975070: 3D Custom Line Style Containing Mesh Not Displaying If Located in DGNLib or DGN file.

"A custom 3D line style that contains a mesh within the Point Symbol is not displaying properly if it is being stored either in the DGNLib or DGN file. This had previously been working fine when it was stored within the RSC resource file and displays ok in either OpenRoads Designer V8i or MicroStation V8i. It is just when they moved to the CONNECT versions of these products with the line style in a DGNLib that the issue was noticed. This is required so all of the custom line styles are being stored in a DGNLib and are easily transferrable to their clients in DGN format files."

Is there a timeline to correct this problem?

3 years later even in U16 still not fixed but there is a course just how nice is to use 3D linestyles. How ironic is that? https://communities.bentley.com/products/microstation/b/microstation_blog/posts/custom-line-styles-3d-line-styles

Mesh linestyles are the only ones which are able to drop using "drop linestyle" and keep the geometry otherwise they export as simple lines which is somewhat expected and unexpected at the same time. If 3D lines are DGN specific then there should be conversion module which explicitly deals with such non-supported(by Bentley and other vendors) element type. This is unacceptable for BIM advanced company.

I agree that this needs to be sorted ASAP. I tried to create a 3D line style with a mesh and placed it in an RSC file, but that didn't work for me. Please can somebody let me know if that definitely should work in ORD Connect.

It works but only with mesh type and in RSC file. Good luck to get rid of existing lines which are already embedded in DGN file there are no tools to remove them(compress won't work on used lines).
