SELECTIONS TOOLS GRASSHOPPER

Hi there

I wonder if there is some way to sort elements type in Grasshopper ?!

I'll try to explain : I have a dxf file , this file contains different entities ( points , lines , circles , closed polylines , open polilynes ).

I need to sort these entities and bake them in different ways using different components according to the element type.

In a few words I'd like to grab these entities all together , send them in to a "sorting component " and have different element type in to the outputs ( i.e. 1 out put for circle . 1 for lines , 1 for points and so on ) in order to use them according to my needs.

is there a way / component that does this at least for certain entities ?

( what I am doing right now is to use rhino selection tools to pick different entities and then send them manually to different inputs but this is a bit time consuming and may lead to some mistake ).

thanks

Ivan

At its most basic level you can use the Params to identify different Geometry Types. What ever it flags as a Null is not that particular one and therefore you can dispatch the remainder down stream.

There are other ways such as using the Expression "Contains(s,p)" on the results of a panel to identify what the geometry is.

Hi Danny and many thanks for your quick answer

I have never used the param component before but it looks the easier between 2 options provided ( at least under a beginner point of view )

would you kindly attach the definition ? the icons have a different looks on my GH and I am not quite sure I am picking all proper components

if you could also attach a sample definition made using the expression editor that would be awesome

thanks, regards

Ivan

Sorry I didn't save it, plus I like to leave you some work to try and figure it out, aids the learning process :)

The Params I am referring to are the ones in the Params Tab > Geometry Panel the same ones you use to reference different types of geometry from the Rhino Document.

The other Components are [Null] and [Dispatch] both of which are found in the Sets Tab > List Panel. Also [Closed] component found in CUrve Tab > Analysis Panel

The [Expression] Component is found on the Maths Tab > Script Panel with the icon like this: "X|2"
