Hello friends, I’m trying to edit the slope value of a pipe in dynamo. Since slope value is read-only, it cannot be editable. I’m wondering if some knows the formula to find a slope of a pipe. The formula should be able to find 1% slope of the pipe from point A to point B. Following is a formula tha…

Here is an example of how to use the geometry of the pipes to attain what you have, this should help you get to what you need. [Capture]

Hi, For percent slope equals (rise / run) x 100 to convert to % [images] Should be a way of extracting the parameter value though. Have you tried built in parameters?

Hi Thanks @Ewan_Opie for sharing the slope formula with me. In this case, I’ve to find the ‘Z’ value for second point where the pipe should be connected in a way that slope remains at 1%. I’m a bit confuse, how do I find that spot. And what about the built-in parameters that you’ve mentioned?

Awesome, thank you so much @Ewan_Opie for sharing the solution. Bless you : -)

@Ewan_Opie is there a way to set the slope value on pipes in Dynamo? Would appreciate if you share some trick, cuz slope value is not editable.

@kulkul thanks, what I have done is to find the ‘Z’ coordinate of the line before creating the pipe. I need 1% slope value but the value I’m getting is not accurate to 1%. So I wonder is there a formula to find the ‘Z’ value so we could get the 1% Slope? [s]

Did you ever get this figured out?

Here is the script I created to make automatic Manhole with pipe sloping. [Automatic Manhole with rectangular and circular] Create Manhole Final.dyn (372.7 KB)
