Railing rails to be straight between posts

[MichaelWarwick7522]

Currently rails follow the topography when the railing is hosted by topography, however this is not how fences are built, rails are almost always straight between posts. This would also reduce the number of errors generated when rail segments are split into too small sections or bend too much for the junctions to work.

Hi @MichaelWarwick7522;  that's the way railing should works work on stairs and ramps, which is the primary option for the tool.

A work around is to edit the railing (fence) sketch path, select each line apply the option "flat". The downside is you have to select each segment independently (no way to apply this option to multiple selection or to the entire sketch/railing), and also you have to split the path into the segments you want to have different heights.

Thanks, @samuelsanf . That works if you want the segments to be flat (i.e. level), but if you want them to slope with the ground, but be straight between posts, well, then there is this idea! In the image the ground slopes gently and the fence should too, I'm just not keen on getting the builder to curve the top and bottom rails like Revit suggests.

I make this with one Railing; but I have to say itsn't a ideal solution, because:

I have to split manually the railing, and set "flat", "custom height" and apply the value (that you have to figure out with a spot elevation over the topography) for each line segment. Also if the railing is hosted to the topography, the post may be floating (if you don't set the post base height relative to a negative value of the lowest rail, which is simple but I didn't do for this example).
