Make 2D

Hi,

i`m fairly new in grasshoper and i`m having 2 questions. first, i d like to find out how can i get rhino to select an object and make 2d from current view?

also, im looking forward to find out how can i make rhino to select all the objects in rhino scene?

Thanks

What do you wanna make? And do you want to make it in Rhino or Grasshopper? Please clarify

i have the following face of a building in 3D. in grasshopper, i need to make a plane through 3 points as you can see in the picture, i want to know instead of 'me' introducing the points one by one to grasshopper, can i ask the 'the grasshopper' to pick the points automatically? (pick 3 points from the intersections/X-directions/...)

i also need to make a 2D from the same face in grasshopper, how can i do it?

i know this simple command (make2D) of rhino. in which i select the object, set Cplane out of 3points, set the view to front view and make 2D from corrent view. the whole idea is to do all this chain in grasshopper (since i have to do the same thing for 100s of drawings!)

thanks

Mh, I guess so, but I would need to have a look at the rhino file.

i also need to make a 2D from the same face in grasshopper, how can i do it?

You might could use Project to plane. This copmonent you can use for current view as well. The plane defines your view.

thanks for your help. here is the rhino file.

i still need to know how can i ask grasshopper to "select all the objects" in the rhino secne and introduce them as a geometry in the canvas?

take the geo compontent and set on multiple geometries

thank you very much, that was a big help and yet made me realize that i still have alot to learn! -)

anyway, i found an easier way of making 2D which is 'creating a surface through the lines (instead of choosing 3 points!) and set the Cplane on the surface, set the view to front view and make a 2D of current view..

i have this boundary for each face, so in GH, i used the planar surface and take the boundary as "edge curve" and here is the surface! now what i realy need to know is:

1-in grasshopper, how can i select an object by its layer? (since i have the same layer of boundary in every 100 files! so i dont need to select the same layer in every other file) .

2- is it possible to change the view in grasshopper anyway?

3- i`ve tried local code export before and it worked, but why in this case, its not working?why when i select the multiple Geo, it makes a surface on lines?!

thnks
