Visibility of point in Site

Hi Everyone,

Ive seen a tutorial about this a while ago but cant seem to retrieve it.

I am trying to set up a definition where the selected point shows the visibility at that position, my problem is that id like the line to stop when it hits one of the nearby buildings.

Thanks in advance

Thank you for the quick response!

Michael, works like a charm. I wasn't aware of that component. The noly thing in my model a couple of rays go through, but im guessing that might be because of the complexity of the model or the lines not closed. I hope this helps others.

Cool.

Any ideas how to do something similar in 3D?

Say you have a tower and want to know if a particular point on the facade can be seen through a number of obstacles on a number of locations on the ground?

See attached screenshots

I have tried intersect, but first I have to boolean the ovbstacles to ony have 1 brep, and the it counts every intersection, so at the front of the obstacle and at the back ... no good :(

Thanks,

Peter
