I’m trying to get an understanding on how feature lines are shown in the 2D model.
All lines below the top are hidden by the Top Mesh, but if I exclude some of the components from the Top Mesh, their defining lines at the top are almost always removed from being displayed in the 2D model.
See the image for an example of the cross-section of tunnel I’m working with.
If I remove the tunnel roof from the Top Mesh, the feature lines at the top of the roof are still displayed, but if I remove the clearance boxes from the Top Mesh, only the lines at the road surface are displayed. The same works for the sides. If I remove the wall from the Top Mesh, only the bottom lines are shown.
Ideal situation would be where all lines are shown according to the settings in the feature definitions.
