Stair's hidden line squiggly

DangCad1 — Wed, 03 Dec 2025 18:39:16 GMT

I am trying to place a stair in my floor plan. and want it to show solid lines below the cut and dashed lines above the cut.

I've chosen "With Break Mark: Visible - Hidden" in Floor Plan Display. Unfortunately, the object seems to have some kind of squiggly line chosen for the hidden part, see screenshot:

If I choose to override object's line types, I can't choose different line types for visibile/hidden - so when I pick solid line there, the whole stairs shows as solid line:

What can I do to fix this? Is there a way to either change the stair objects inherent line types or to choose different line types for visible/hidden when I override the object's line types?

Operating system used: Mac Apple Silicon Sequoia 15.3.1

Expand the "Floor Plan Display" setting on the left, and under "Grid and Structure", check the various line types settings (see image below) for the Hidden Part (above the Break Mark).

Hi, this solution is not working for me. I have the stair set to "with break mark visible/hidden". And I have all grid and structure lines set to "dashed" but the stair above beak mark still shows a solid line. What am I missing?

change your library part (top center) from "Built-in stair grid" to "stair grid"... funny enough, this came up in a training q&a session just last week, so I have a vid already spun up!
