That makes sense for sheet goods.
For my 3D parts, like these machined 2x4 blocks, what is the best way to import them?
Adrian wrote:Cut3D would be better for that as it supports four side machining. It can be done in Aspire but it's not something I do.
It's best to work through the tutorials on the main site - http://www.vectric.com - as it's not the sort of program you can really learn by having a go. There are important concepts that, if not understood, will lead to lots of frustration and an incorrect view of what the software is capable of.
Not sure what 3D package you're using but it created a lot of redundant geometery on the STL file you posted.

The challenge with any program will be stock alignment and rotation. Again, going only by what I see, I would do two sided machining (very easy) and create a positioning jig for a drill press to do the small holes. Next step up may be some type of indexing device that is under software control.

Also tried importing to Solidworks, it went through the import process but nothing came in. Seems like the STL file isn't valid???????

2D machining is far more efficient than 3D machining. Machining time will typically be 50-75% faster using 2.5D toolpaths.
If you want to import a 3D model, you're probably going to need machine all 4 sides independently, unless you have a 4th axis to rotate the part.
3D models and toolpaths are really only needed when doing more organic type surfaces, or carvings. Any shapes with flat surfaces should be done with 2D toolpaths, imo.

You say "it can be challenging to get good vertical sides with 3D toolpaths." - can you elaborate? I haven't done any 3D work up to now,
