Grasshopper

algorithmic modeling for Rhino

I wanted to create a parametric panel based on some simple lines, With the intersections like a waffle connection.

I'm having trouble getting the edges to bake properly, I'm still quite new to grasshopper so I'm not too sure if there are better nodes to do this.

Any help would be appreciated.

Thanks Guys!

Hi Shuwei, 

I am not sure I quite understand your purpose yet. So for either "horizontal and vertical" or "full panel", you want to obtain the edges for the breps? I have a simple solution for you but maybe it is not specific for you. Use the brep edges component under surface tab. Then according to the input data tree structure, you can have your edges flat or separated. Picture below is the output for brep edges with input from full panel. 

Let me know if you need anything specific :)

Hey Sen, Thanks for that fast reply,

What I'm wanting is to have the notched pieces generated from the edges so I can bake it into 2D linework for fabrication.

Currently, the highlighted pieces are not being baked for some reason.

Also is the way I'm going about generating these notches really convoluted and long?? Is there a simpler solution to generating the notches??

The current method is moving it along the x axis, then using a trim solid to get the notch

Hi Shuwei, 

The reason the last one can't be baked is because they are invalid brep. If you attach a panel to it you can see it. Like below. So now you know the reason, from where i see it, there are two ways to do it. The first one is to use the brep wireframe to extract the lines, which are essentially what you need. The second one is to to use solid difference to create the brep, the result however is that one is invalid and the other one is closed (which is good). I'm not sure why the first one is invalid, you should check that out by comparing it with the good one. As for the method, i think a quicker way would be using loft. As you already have the lines, and for different types of member you have consistent cross sections, so you can create rectangles separately and then loft them. I guess this could be neater. 

Hey Sen, Thanks so much for this!!! Definitely taught me a lot about Breps.

I'll give it ago, will post results after I fabricate it today

No problem :) Best of luck!
