segment section lines which are not perpendicular

[duanx]

I received a request from our Enterprise Priority customer recently, they want to create a section line for the stair below:

Currently, we can create segment sections lines, but they must be perpendicular or parallel to each other. Their workaround is to create two separate sections and combine them to make it look like one section.

If we can choose a random line and create the section line accordingly, that would be great. For example, create a section for a curved stair and parallel to the curve center as shown in the image below:

Thanks!

it's been 8 years now since people are demanding this, it takes Nothing to add the feature and yet FOR 8 YEARS it's still not added ...
