HELP, I'm noob I can't find how to union 2 meshes

My goal is to make a very long road (vertically curved). Like typical GTAV mega ramp map. (look img)

I started working with UEFN just a week ago. I’m still learning how to do basic things. Until now I achieved creating a vertically curved part of the road, now the thing would be to copy paste and unite each of them so the result is a really long road vertically curved with ups and downs all the time. How can I fusion/make union of 2 meshes while adapting its pendent??

Is there any more easier way to do a super long road ramp ? *It is in the sky so I can’t adapt it to the floor or any land.

Hello, Welcome to UEFN / the Forums.

There’s a modeling mode that will allow you to Union those meshes:

I’d also take a look at the Landscape spline based road system.

Let us know if you have any more questions.
