Solidify without overlap

Question Modeling

Hi, I am trying to create a solidify type function that only solidifies on the x and y axis and without overlap. I have managed to get it right apart from the overlapping part. For that I tried to use a proximity node to limit the extrusion amount but it has been days and hours of trying and I have still not gotten it right. Here is my node setup, I am not sure what I am doing wrong?

    Hi ccooljjj33 ,

    Here's an overview (of some of the mistakes):

    Oh, I just noticed I misspelled Length once 😉

    ...and what's more, the Length of a Normalized Vector is 1 (exception: the null Vector (0, 0, 0) has a Length of 0).

    Thanks! Any suggestions on how to correct this? I have spent another 10 hours trying to get something working but no luck. I got close by using a raycast node but still struggling with the limiting bit. I previously managed to get it fully working using bpy but it is too slow and thus the reason for wanting to try the same in Geometry Nodes. This is my first time using it and it is a bit confusing.

    I don't even know exactly what you are trying to do, sorry.

    Maybe start with something simpler first, there is a lot to learn and Geometry Nodes is very powerful, but in my opinion, not very intuitive.
