Projected 2D Simple Sections

Hi!

I started using Grasshopper last week and even if I am trying hard, I'm still facing problems to understand the basic concepts of the program. So, I know that it's probably easy, but I just don't to how to work with sections yet.

I would like to make a simple 2D Section, passing through a specific place.

I've done five geometries and a vertical plan in Rhino, and I would like to make a section where those two intersect. I was abble to make it (force in a wrong way) but it is only giving me the lines where the geometries intersect the plan, not showing the backwards buildings.

Can someone explain me how I do that?

Sorry for my english and let me know if you don't understand what I'm saying.

I've attached the .gh file and a image in order to be more clear.

Well Jose

I have this for training my people in my practice.

Unfortunately it uses code because any job in the practice is performed that way ... but the Mesh Shadow native GH component can do the same job (option 2).

I've "expanded" some things (in native components) to help you and added (internalized) your profiles/extrusions.

And although irrelevant with your request ... see this as well

Hey Petter!

Thank you very much for your help. I am now trying to understand the codes, because as I said, I'm kinda new on Grasshopper so it's being hard to figure out everything haha.

Can you explain a little bit more the part you said "Unfortunately it uses code.."? There isn't a easier way to do it? I just want simple 2D sections, like the SectionTools from Rhino.

Well ... the "trad" way (unless you are familiar with coding) to help a novice is to provide a solution based solely on native GH components; no C# that is. But I had a very limited time for that one - thus I've provided whatever was ready.

Easier way to do it? Well ... it's a matter of perspective, he he. But "in general" several things are achievable via native components. Potentially the "simpler" the case ... the less "justified" the usage of code may appear. That said there's cases where novices are quite familiar with coding ... but that's rather the exception than the rule.

Anyway at some later time I'll provide a native solution as well ... unless some good Samaritan could do it in the meantime.

On the other hand if we are talking about very complex Breps ... well ... but that's not an issue for the present time.

A native solution would be very kind!

I understand. I'm not familiar with coding, maybe that's why I'm having trouble with the previous definition.

Anyway, thank you very much for your attention! Sorry for that rookie doubt haha.
