Custom Line Styles

Hi all,

I'm trying to create custom line styles in OpenBuildings Designer but having a number of issues.

I'm following the tutorial here: Create a custom line style - A tutorial - [Archived] AskInga Wiki - MicroStation - Bentley Communities
The tutorial is over ten years old, but still seems to be accurate to the Line Style Editor tool. Is there a better or more up to date tutorial I should be using?

I can create new stroke and point components as the tutorial suggests, but the line always appears solid regardless of length or placement of dashes. Furthermore, I can't get any points to display on the line when I create a compound component. I thought I'd download the example file from the tutorial to compare with how I've created mine, but the line from the tutorial is displayed in exactly the same way (i.e. no gaps or points), despite having the same settings as is displayed in the tutorial itself. I've included a screenshot with the example file.

Does anyone have any advice on what may be causing this, or on creating line styles in general? Thanks in advance!

Tom
