If there is one manners more general, I definitely want to see it. 

There is, and it is by pulling the ground over a mesh. So you would create a ramp mesh (ground), and then pull the ground over it. It works better than the old code, and you can do much more with it as well. Here it is:

The brush size is now in BJS units. I also added some example shapes you can uncomment.
I like how elegant the new addRamp function has become

Edit: I fixed a wrong ray length in the code, added a new option to not let the ground go lower (allows ramps to go through each other), and corrected the comments:

Hi Gijs,

Woaw, it's really excellent. I will use this solution on my editor. 
Thank you very much for this new addRamp function

@Gijs as Dad72 says "excellent". Very impressive

Hope we see more from you

cheers, gryff

@Gijs Hello, Have you any idea how to put the texture correctly on the sides of the ramp so that it is not widened.
I mean when the ramp is creating, the texture on the sides is large. Is it possible to re-scale to avoid this texture large.

Thanks again

Hi @Gijs,

I'm coming back to you because you're the author of this feature that worked well before. But now, there is something different depending on the click and I do not know why.

I told myself that you can understand better than me what happens. Try this PG to create multiple ramps in multiple directions. they are not placing correctly.

I also noticed that if the terrain is not subdivided enough, it does not create flat ramps anymore. and if on a ground of 500 * 500 subdivisions of 500 are made that ground lose a lot of performance. And the bigger the terrain, the narrower the radius of the ramp (it would take a multiplier ratio, I guess, depending on the size of the terrain)

The ideal would be to subdivide only the part of the ramp. You think it's possible?

Thank you for your help.

If only I could remember what I did to fix the positioning.

I ended up using a ribbon instead of a ground. This way, I create the ramp shape based on 4 clicks/picks. One for each corner.

Click 4 times to create the ramp.

Pretty one. It's perfect. That works well.

Thank you Raggar
