I'm trying to convert Bentley Microstation DGN files to work with in AutoCAD, and I'm frustrated by the exported linetypes in the DWG files that really don't look anything like Microstation.
For example:
- the Microstation linetype "DGN 4" for centerlines in my drawings, is a long dash - short dash - long dash style
- the exported "DGN Style 4" in the converted DWG file is a long dash - dot - long dash style (why??)
The ACAD linetype definitions for CENTER, HIDDEN, DASHED, and PHANTOM are visually much closer to the Microstation standard linetypes, but still clearly different. My goal is to align the DGN and DWG native drawings as close as possible, since we work extensively with both formats.
I can't find any information that helps me to understand any reason for the differences, so now I decided to try and approximate the Microstation linetypes by painstakingly measuring the geometry (see the example screenshot below). I actually created a substitute linetype for DGN Style 4 that in test plots is virtually identical to the Microstation plotted drawings, at 1:1 scale.
This is how I defined the linetype:
*Custom DGN 4,DGN Style 4 ___ _ ___ _ ___ _ ___ _ ___ _ ___
A,3.175,-1.567,.7625,-1.567
I'd like to know if anyone is experiencing the same issue and has a better solution?
FYI, below is a screenshot of all 7 of the standard Microstation linetypes.

Welcome to the AutoCAD Community Forum.
Converting files from other software can be challenging and frustrating - believe us, we understand.
I recommend using the Express > Tools > Make Linetype (to create exact or similar linetypes in other software).
Attached is an excellent resource to learning linetype creation.

@valentin and @Tomislav.Golubovic,
Thank you! I really appreciate the quick responses and the resource information.
I still have to admit, I'm really disappointed (and annoyed) with the default linetypes from DGN to AutoCAD. If only I had known to investigate this issue sooner, I might have saved our drafting team from considerable frustration with the drafting appearances, created custom linetypes and modified the import/export settings to align the drawings.
