Joining / Merging multiple overlapping assymetric surfaces

Rhino Rhino for Windows

Hi!

Im having problems joining/merging multiple overlapping assymetric surfaces. Some of them are overlapping and could be erased or merged into others .
What I want to do is to make all the blue into one surface, project them onto the curved surface, and make them a thin solid, like a lasercut board material. If I do it as it is now the file is going to be huge! and hard to work with.

Thanks for any help!

Can you attach your file?
If the height is the same, CurveBoolean could be of help (then eg. split the surface - instead of projecting - and extrude surface).

Thanks! That seems to be a great tool, however using that tool Im going to have to select 10.000 something areas :confused:

Booleanunion it and then MergeAllFaces ?

All normals are pointing in different directions, otherwise a boolean union might work, i created multiple meshes from the surfaces (same number and place as the surfaces) with the normals all in one direction, now i just have to find a way to reverse the meshes back to surfaces with normals in the same direction and try the boolean union operation?

Does not work beacause of the normals in different directions

I thought there is a function like. MatchDir

Can you post your file?

There is… If you write one… :smile:

The following will orient all selected surface normals to “facing up” in the World coordinate system

Nice function! but it seems it only worked for some of the surfaces?

10

Tried to upload the zipped file but maximum size is 3MB it says :\

11

Seems like some of the surfaces are twisted or…

Yeah, in that case you’ll need to put is somewhere where people can download and post a link…

Looks like corrupted archive to me (using 7Zip).

Get rid of extra geometry, _Purge, and check “Save small” while saving. It should compress under 3MB.

Here is a Google-Drive link! I cant get it to compress under 48Mb

How did you create this file in the first place?

If I use SelBadObjects it gets a couple. Also. If I ProjectToCplane. 90% will be deleted… Very odd things happen here.

I dont rememer exactly but u think i drew a tapered rectangle and copied and scaled a couple. then draged them out and put them in a random order, and then I copied this and rotated a few times. Then i deleted the parts that extended outside the rectangle. Maybe I made them in to solids in one step and then flatted again, dont really remember.

That is how I remember it at least. You think I should just redo it in some way, are the faces not flat?

Found a way to do it manually: Make2d - Patch the whole rectangular surface - split with the Make2d lines - Put the original surface network over it in top view and manually delete all the surfaces in between, they are much fewer…

Thanks guys! This is a great forum!
