@adrienneverdefinegardens0131 I presume when you refer to groups in your post you are talking about Tag Folders. There have been a few reports of other users not being able to edit the color or dash style for tags in tag folders in SketchUp/LayOut 2026. I've been doing some testing and I'm not having any difficulty, though. Even in your file I can change the color and other parameters for dashes in LO. Here's an example in which I changed the color and scale of the EX TREELINE tag.

I see incorrect tag usage in your model. ALL edges and faces should be created and remain untagged. Tagging the geometry can create a number of problems including adjusting the dash styles as well as colors. This is the result of correcting the tag usage.

Purging unused content in the model.

Although not related to the dash and color thing, I notice you've overridden the Camera properties for the viewport. This can be a problem especially in cases where you've added labels and dimensions linked to the viewport.
