How to generate 3D solids with point information?

Hello everyone!
I have imported some point with coordinates to Paraview via txt file. Its position distribution is shown in the figure.
It should be noted that I know the numbers of the imported data points and which points can be combined to form the correct triangle surface (number of data points on each triangle surface). In paraview, I want to generate 3D solids from these data points. How can I do this?
I am looking forward to your guidance!

hi @zhao ,

I’m afraid that information is lost in point cloud. You could try recreating it manually and then use ResampleWithDataSet but results will not be great.
