Grading

[ryleyFEQWE]

First of all, i am very new to C3D other than some experience at school 3-4 years ago.

I attached two files, one of the drawing i'm currently working on and another (JPG) of a finished site i am basically trying to recreate/copy. (i do not have the original drawing for the JPG)

I am trying to copy the drainage design while learn the most i can from this for future jobs.

I'm trying to add drainage swales to the front and back of the trailers (running south), as well as in between them. I assume the trailer pads will most likely have to be raised above eg.

Trailer pads are to be flat

I'm trying to have a minimum slope of 2-3%.

Shooting for a 150mm - 200mm elev. drop from trailer pad foundation to the nearest swale to reduce flooding risks.

I need a 4m distance between trailer and top of embankment around furthest south trailer to allow future access behind the units (i believe i have done this)

Like i said i am very new to this, as it is a big learning step and making me very frustrated. I have tried adding feature lines for the swales but i am having a hard time.

any info on how i can make this easier would be very much appreciated.

@ryleyFEQWE ,

What a great looking project! Thanks for bringing this to the community, while we can't comment on the engineering or design I can at least point you in the direction of how to add grading objects via some online help documentation and maybe a video to help you get moving to your end goals.
