inconsistent stair cut line visibility

[jagostinho74]

Hello all,

Finding that the stair cut line visibility is inconsistently produced for a mirrored version of the same stair.

It can be fixed via changing the View Range with a Plan Region but  it just seems a bit odd to behave this way so I thought about sharing it with the community.

Is this intended behaviour or can it be classified as a bug?

RVT attached.

Thank you

I have similar, but different, issues with stair cut lines not being consistent from one run of stairs to the next with the same view settings. I think the issue with your stair is that the cut line is being drawn from the same side of the stair at the same elevation/height, therefore same tread, and it's the direction of the cut line that is altered depending on which tread the cut line generated from. Instead of mirroring the stair, try drawing a new one in the opposite orientation and see how the cut lines behave. Otherwise, using a plan region is the only option I can see, and then stairs graphics can get weird with plan regions.

Enter a negative value for the Cut Line Angle.

That will work @barthbradley , but I will loose the consistent orientation of the cut line and will require to duplicate the Stair Type. Both of these are not desirable.

That's right, @mpukas . We are currently using Plan Regions to go around this problem. I was just wondering if there was something that I was missing.

I think I would duplicate the Stair Type.  This way I could identify the mirrored stairs in the Project. That information might come in handy -  especially if I need to troubleshoot other oddities cause by mirroring the stairs - which Autodesk warns us not to do.

That is an interesting point you make, indeed. There is some value on tracking which elements are being modelled with techniques that deviate from Autodesk's recommendations.

I was having this problem and your recommendation worked for me. This is a townhouses project, where all linked models are the same but I made them making mirrors in the early stage of the project, Everything was fine, a good view range. Thank your for the solution.
