Hi guys,
To the point:

  • Can I create a new joined poly-line or a curve directly through boundary (Just like in hatch) in Rhino? It will make my design process much faster.
    -Is there any way to add curves/surfaces/meshes…etc to the existing curve/surface…components in Grasshopper by adding or selecting only the new curves/surfaces…etc (Just like _AddToGroup command in Rhino?
    Thanks in advance,
    Elshar

Hi Elshar - I’m not sure I follow the question, quite, but

DupBorder will make a curve from the border of a surface or hatch
PlanarSrf will make a surface from a closed loop of co-planar curves.

Does either of those work for what you need?

Hi Pascal - No, that’s really not what I meant.
1- Let assume that I have a rectangular that has been exploded into many lines. Can I click just in the middle of the rectangular to create a new joined rectangular. (I don’t want to use the commands join or connect, chamfer …etc) because I have complex shape to create from single lines (the border between them).

2- In Grasshopper, Let assume that I have a curve component on the canvas, I add a single curve to it.
How can I add extra curves to the same component without needing to select the previous selected curves, nor losing selecting them. (Like the Rhino command _AddtoGroup).

Hope you understood what I meant!

have you tried with _CurveBoolean? it Trims, splits, and joins selected curves based on their overlapping regions.

Hi Diego,
I am aware of all these commands above. But it’s not what I tried to explain above also.
It’s different to create a shape with just one click through un-joined lines and curves than with many clicks.
Thanks any way :slight_smile:

can you post an example? maybe in another program or so. I 've read your first and second topic twice and still don’t get what do you want haha

Hi Diego,
I will set the two request into points.
First:
- I have four lines that shape a rectangular as below.

- I want to create the rectangular shape between these four lines without needing to click four times using any of the commands (join, connect, chamfer,…etc).

- Instead I want to just click once in the middle of the rectangular shape to create a new joined/connected rectangular shape.

:: Because I have many complexes shapes that have been exploded into lines, and I want to create a connected curve that results from the intersecting lines.::

Second is for @DavidRutten:

In Grasshopper, Let assume that I have a curve component on the canvas, I add a single curve to it.
How can I add extra curves to the same component (Curve) without needing to select the previous selected curves, nor losing selecting them. (Like the Rhino command _AddtoGroup).
Because when I add new curves, surfaces,…etc and I want to add more to the exact same component I lose the previous selection.

that’s why I suggest you to use curve boolean, it works like the Hatch you mentioned

Sorry Diego I guess I missed this, and thanks a lot :slight_smile: that exactly what I wanted.
Do you have any idea about the second issue :sweat_smile:

about GH I have no idea yet, someday i will try it I guess

Either you make another curve component and use merge. Or go to “manage curve collection” in the right mouse button where you can add curves, but unfortunately only one by one.
