Working with .stl files

Hi I am working on a project where I am taking scans of the two pieces of a broken weld and trying to put them back together and I'm wondering if there is any program that can do this?

 

Some more information, I welded two pieces of metal together and then broke the weld. I then scanned the two pieces. Now I am trying to recreate a water tight model of the two welds together. The file format currently is .stl

Welcome to the forum. :)

Very interesting, sorry I can't help you with that, but be patient somebody will be able to.

Sounds like it might be a job for INVENTOR.

I haven't been able to find anything yet. I've tried editing the .stl file of the mesh but I haven't found a good way to do that. I also looked into converting the mesh in the .stl file into a solid but I also haven't found a program that will help me either. The problems are

1. The mesh contains around 150,000 points so conversion into a solid format creates a gigantic file

2. The edge of the weld is not a straight line so I need to find a program that smart enough to connect two jagged lines.

3. The final combined weld needs to be water tight because I'm going to be running tests on it in Abaqus

I always just drag/drop the STL file directly into the Modelspace drawing area in AutoCAD and it imports just fine as a 3D Solid. Have you tried this?

Can you post an example of this?

Do you have deep pockets - make that very deep pockets?

Here is a simple sphere.stl

can you demonstrate how to get this as a solid in AutoCAD?
