can i save the output results of vedo in any readable format of point clouds (las, ply, obj, off, ...)?

Yes, obviously! E.g.: mymesh.write("file.ply")

Thank you for your prompt response

Actually my question was not very clear. I have a set of drawings including, mesh, lines, planes, ploygons, graphs and points which I can see them easily in visualizer. My purpose is to connect all these seperate objects into one and then write a file from all as a new mesh/object file. Could you please let me know how can I do this? Thanks in advance

You can use function merge(myilstofmeshes) to merge multiple meshes into a single one, but this probably not what you want to do.. If you want to save a whole scene made of multiple objects to file, such file will not be neither ply nor off because these do not support scenes. So:

you can save multiple files one for each mesh object and their position in space as ply
you can export a whole scene as a numpy object which contains all the info needed by vedo to recreate the scene. This is obviously specific to vedo but can also be read by other numpy-based applications (this feature is still a bit experimental and might not work perfectly .. but i'm available to improve it if needed). Usage: exportWindow("scene.npz") plotter = importWindow("scene.npz") Or from command line try eg vedo https://vedo.embl.es/examples/geo_scene.npz

Thanks

I need to create a dwg/ dxf format of my results that I can open it later on in Autocad or similar softwar, is it possible to convert .npz to such formats probably?!

I have also another question, which will be very helpful if you could response. AS I mentioned, I have several 3D lines which are the borders of a 3D polygonal shape. But as I used the Line() command, they are disconnected. I would like to make a 3d polygon which fits inside these 3d lines/borders, is it something I can try with vedo? thanks

another question is how/if I can fit a plane inside a specific border points, I already saw there is an example which detects the border points of an existing plane, but how can I fit a plane inside the border points?

I am thinking may be I can fit planes inside the points and then merge all planes as a ply file which I can get usuable output of my data Is that possible? thanks in advace

Sorry VTK does not support (afaik) those formats. You may need to write a converter from ply or numpy to those but I guess that would not be trivial.

This sounds possible... You can disregard the lines as such, just take the ordered points and create a new line then you can try e.g. line.triangulate() or line.tomesh()

how can I fit a plane inside the border points?

what do you mean? You can fit a plane to points with fitPlane(pts)
