Workaround for collinear walls?

[TeenyKitty]

Got it (I think).

Draw a CAD line parallel to those walls -- well, parallel to one of them. Dimension from CAD line to both walls, observe difference. Select the wall that needs changing, then select the parametric dimension and alter it to match the other one.

TK,

You are using the wrong tool.
The Make Parallel/Perpendicular doesn't align - it only makes, ......DA, DA .............parallel or perpendicular.
You can use one of the align tools or drag and snap to the other wall.......
