Laying a mesh directly over another mesh

[Anonymous]

Hi guys. Its a bit difficult to explain but im designing racecourses and i'm loting the main road and i want for the racekids another mesh directly over the main mesh. But i cant use the main loft because surely the perfect racingline is different. So im creating a new loft which fits with the racingline but when the racecourse has elevation changes its a pitty because right now im doing every vertices on the right place with my hand. Is there any way or tool to tell the new loft it should fit exaclty over the main mesh? 

Hope you understand what i mean.

Greetings 🙂

I am not sure I fully understand the question but would projecting the original curve to a surface help?  Posting a picture and/or Max file would help to understand what you are trying to do.

Thanks for your answer 🙂

On the first picture you can see the racetrack from the top. Now i want to add the racingline (the texture is full with tire marks) which is logically not completly in the middle of the track so i cant use the loft of the main road. The most tracks are not completyl flat so when i create a new loft for the racing line (the black mesh on pic 2 and 4) i always have to move every vertices exactly to the main road (actually a few cm above ) And thats a lot of work so i want to know if there is a way to do it faster? To tell the loft or mesh that it has to fall exactly over the main mesh?

why not clone the original mesh and just increase its z height a cm or two, and then give it a new material?

You have to read carefully 😉 The racing line is not in the middle of the track. I'm sure there is a faster solution. Something like scatter for example.

Try experimenting with the following approach.

Convert the lofted racetrack to a NURBS so you can attach the raceline spine to it. Now project the racetrack line (spline) to the NURBS. Detach the projected line from the surface and use it to loft the surface to which you want to apply the raceline texture.  You may need to use opacity maps to trim the texture.

Thanks for the help but an user from another forum showed me a super fast solution. I just used "cloth" and it works perfect.

Thanks anyway for your time!

Please share how cloth modifier made you successful.

I used my racingline mesh as cloth and the main track as collision object. And then i pressed simulate and it will fit perfect to the surface of the main track 🙂
