Intersection Point on Block reference/3D Solid

Hi All,
I need to calculate the length of the visibility line from the proposed surface to the signpost which is in the form of block/solid, do we have a code block in dynamo to get the intersection point?
I have attached the snap shot of the requirement.

Hi @ansarimdnazir ,

I would suggest creating a plane from the BlockReference in the direction of the sightline, then you can intersect that Plane with your Alignment to get the intersection point:


Possible workflow:

Hi @ansarimdnazir,

The Sight Distance tools might work for this.

If so, then there is a node in the Civil 3D Toolkit package that essentially replicates the functionality in the UI.


Maybe give that a try and post back if it doesn’t get you what you need.
