Grade Slope Along Surface

Digitally signed app

月, 年


This app uses a unique algorithm that extracts data from the selected tin surface and performs trigonometry calculations to draw a 3D polyline along the tin surface at the desired grade/slope.


3D Polyline vertices are computed at the triangle edges resulting in vertices that match the surface data. Converting the 3D polyline to a feature line results in grades that accurately represent the input grade/slope.

    If your time is valuable this is a must have app when doing landfill final cover design with benches, tack-on berms, access roads and in general drainage channels.

  • Very Helpful

    Great for a constant sloped ditch (especially around curves). Can be used for tack-on berm onto a graded surface. Can even be helpful to plot a constant slope path along an existing surface. Well worth its price.

  • Great app!

    Coming from a Microstation and Inroads background, where I used a command similar to this on an almost daily basis for landfill design, I was lost trying to lay out diversion berm slopes without it. Luckily I came across this app, and it is a lifesaver! It works great, and saves my projects time & budget!

  • Works Great!!!

    This product works great to cut in diversion berms on landfill covers. This easy to use app saves hours of work and allows for numerous iterations with little effort. I don't know how I got by without it!
