I am trying to model intersection for 4 roads. These roads are located at different elevations. How do I model intersection surface that will connect all these roads? I tried patch but it doesn’t connect to the road edges
Note that you have a tolerance of 0.001 millimeter in your file, and the width of the road is like 260,000 millimeters. I’m not sure if that is actually a 260m wide road or if something is off with the units. But using a 0.001 mm tolerance for an object of this size is way too strict, and the produced patches will never join.
The “old” patch (avaible in v8 as Patch and in v9 WIP as PatchOld) is able to produce patches that can be trimmed provided the tolerance is increased to a value that makes more sense than 0.001.
if you are running v8 why not just increase the area for patch, these edges then might have less issue being connected, also you can still increase the area to connect all branches of your street in one go in the same manner. might be cleaner either rather than making a patchwork of dozens of smaller surfaces. just stick to the outer edges without inner curves that will help you get a usable result.
