Hello, I’m trying to divide a surface into equally long pieces, and then deconstruct that to get the same edge from each.
So when I do this with a single surface, I can easily get the edge I want, let’s say I want to get the vertical edge on the right:
But when I split a longer surface into many pieces, deconstruct Brep edge doesn’t give me the same edge of each surface consistently, I would like to be able to get the same edge from each surface at once.
this is the issue:
How can I consistently get the same edge from each of these surfaces? Thank you!
Could you send your file with internalized surface and curves?
I’m not sure if split surface is consistent, but why shouldn’t it be… (or maybe it’s behaving differently on the far left and right end of the surface, where it’s not splitting)
Either you’re sub surfaces have not the same normal orientation, or UV has been swapped…
My guess is that the curves you’re using are not all in the same direction at first(?)
Hi Renan, List item is indeed inconsistent. If you’re frequently changing your definition inputs, I’d recommend to select your brep edges using another logic. For example in your case you could measure each edge length, and select only the two biggest.
I think you’re right Antoine, the curves I’m using are not all in the same direction, perhaps because of something happening when I contour the surface.
Erik, your method works for me, but I also need to divide the surface into a specific distance, that’s why I have been using contour. I think either I find another method of selecting the Brep edges as per Felix’ suggestion, or I can find another way to divide this larger surface into 2meter pieces. Any suggestions?
To keep a more consistent output, you could also compare the selected edge to a certain guide vector (X-axis here), and flip the curve if the curve is reversed :
Once you’re happy with the consistency of your edge selection, and you find it flexible enough, you can place it inside a cluster to keep an easy reading definition.
