I’d sack whoever made that file.

Depending on the final purpose, you can also try surface retopology
The scanned 3D model is useful and can be transformed as you need, especially for some realistic renderings.

I’m not sure what the person who drew that corbel was trying to accomplish. Almost every straight line in the model is broken into numerous short segments. You can see this if you turn on endpoints in the style.
There are also places where it seems an intersection should have occurred, but didn’t - no endpoint marker where these edges cross.
This could all be fixed, for example by drawing new edges over the existing divided edges and across missing intersections. With that done, faces will form everywhere except on curves. Fixing them will involve tedious stitching across between endpoints on one curved edge to the opposite one.
As you might conclude from that description, fixing it will be essentially the same work as starting over and redrawing the corbel using the dwg as a reference.

Ok… Thanks for looking into it. I appreciate it…
Yes you are correct. I am no SketchUp master but I am 100% certain that model is from a Occipital Structure Sensor. I know because I bought one. It’s now a $500 paperweight until I can figure out the software. Occipital charges $29 a scan to convert it into a SketchUp file but you can do it yourself. Here is the link to the instructions.

There are several articles here on this forum and the Occipital forum is pretty dead to be honest.
I agree with @Jim-Tzu . Not sure if the file is from the Occipital Scanner for sure but I have used Pointfuse and CloudCompare to generate similar meshes from my Leica BLK360 scans and export to .skp, obj, fbx, etc… Converting a point cloud to a detailed mesh is never clean and always results in a high quad / tri count., Per @mihai.s Meshlab is a great tool for retopology.
What’s the intended use case for the model? Develop prints for a carpenter to replicate, develop a mold for a manufacturer to duplicate, or strictly for visualization purposes?
Sorry for the late response Jim. I appreciate you taking the time to look into it.
Strictly for visual purposes. Thanks a lot for looking into my issue. I appreciate your time and helpful feedback.
