Linedef Intersection without creating a vertice.

[Jacek Bourne]

How can I draw multiple linedefs that intersect without vertices being automatically generated at the intersection(s). If there is an option to toggle this then I’d like to know what it’s called and where it is specifically.

There are multiple methods, but if you're using UDB you can draw two lines separately, then drag the vertices so they overlap. To prevent vertices being generated at intersections, go to Edit menu and make sure you have Merge Dragged Vertices Only mode turned ON, and Snap To Geometry mode turned OFF. The latter should be turned back on after you're done, because otherwise drawn geometry won't snap to existing stuff. However the former option should be left on when you're editing a map that uses overlapping lines that do not intersect, because otherwise UDB will automatically generate vertices to the intersection points.

I believe a vertex is needed for a linedef. That's just how the engine works, doom.exe needs to register the x and y coordinates of the vertices to understand that a line is there. Why don't you want vertices anyway?

I’ve seen and looked inside wads that have linedefs crossing without a vertice at the intersection. As example is the holograms in Deus Vult 2’s map19 Stargate which is pretty much what I’m trying to do.

I see, I completely misunderstood what you were trying to achieve. Sorry about that!
