I do not know how much this will help, just some ideas to try.
- If you drag a selection window from left to right SW will highlight only complete entities which you should then be able to delete. I contrast dragging the selection window for right to left select everything the box touches.
- To reconnect I might try to save in multiple files, then delete all except one of the features, then re-insert each feature into a new file, or assembly.
- If these features are tubular, just cutting off the ends should show as hollow. If this is a solid there may be great difficulty in achieving your goal, my first thought would be to try a shell, but I doubt that it will work due to the surface irregularities.
Hope this helps some.
Hello Bryant.. my first look/thought.. the content looks extreme and imho, not something you should be working in in SolidWorks.
It would be advised you edit, merge. reduce and cleanup the data in another software package (modo, blender,..) which better handles polymesh data... and possible convert it to a manageable nurbs surface.
SolidWorks has two options importing STL:
- Importing graphics only (not editable). Most likely this is the option you have used.
- Importing editable geometry
The first option allows importing of large model with a good performance. Second option has limitations on the number of triangles and even if your model is within the limit the performance would be extremely slow. Please note in this case all of the triangles will be imported as individual faces.
Alternatively you might look into the ScanTo3D SolidWorks plugin which might help to bring better quality of editable geometry.
Also you can pre-process your STL in 3rd party STL editing applications like MeshLab.
