exact meaning of red highlighting (by John Griessen)
I've gotten some red highlights and they seemed to go away when I removed accidental tiny slivers of empty space in my design.

Now I have some that won't go away. Is there some other meaning to them?

Thanks, John Griessen

I just loaded a newer version that is even tidier, yet still has red highlights.

Now ... really ... (by Roland Frank)
Hello John.

If I got you right you are referring to the red highlighted
"faces", where solvespace just fails to create the resulting
Sometimes a different modelling approach will succeed.
But if I look at your models, you are doing volume
modelling, which will end up no good in solvespace.
Since Solvespace is lacking of a real geometric kernel
it will fail with most such operations.
Believe me, I tried a lot ...
Solvespace is sleek and nice and good for some basic stuff,
but the more complex the models get, the more likely
solvespace is to fail ...

I personally would advise you to take a look at FreeCAD.
Open Source, for Windows, Mac and Linux.

How are you planning to make this part? If you don't need to export a STEP file, then you can switch from NURBS Booleans to mesh Booleans by checking "force NURBS surfaces to triangle mesh" in the first failing group.

Another Example ... (by Roland Frank)
Look at my attached Turners Cube.
Go to G005-Lathe and untick "force NURBS to triangle mesh".
Then re-activate all groups up to G009 and you will
have your "red highlighted faces".

I tried some different ways but this turned out to be the only
way to get the model working ...

@Roland I've used Freecad and was excited to find the parametric solvespace. The red highlights I get are along edges rather than faces. Does Freecad have parametric design now -- I doubt it.

@Jonathan I am going to get it printed with a filament printer in HDPE
for prototype tests, then also make a model of a mold for it, (by doing boolean difference -- even more complexity) to print in ABS. The ABS will be used as injection molding tooling for low pressure molding. I had those slots working earlier, then tweaked them and all red. I'll try simplifying the imported files that define the slots. When it comes to inj mold tooling, I will make the internal cone part of aluminum and mill some slots in it, so the curvy details I have in teh files enclosure-pcb-slots-1.slvs
enclosure-pcb-slots-flanking.slvs might not even make it to the real thing -- I'll simplify and see if red goes away.

I can't access the file to check but if its red edges try just hitting show naked edges.

Sometimes my design flakes out and highlights edges for no reason and when I run that it makes them go away.

Last time I ran into missing faces, I just finished the model - exported to STP and used Freecad to fill in the faces.

Way better than trying to use freecad to actually do work.

Thanks for the productivity hints.

Union vs Union (by Tyson Whitehead)
Was googling for red faces and hit upon this.

In my case it turned out that I really wanted to select assembly instead of union for several of my key pieces.

The red faces went away then.

Figured I would mention that here in case it helps anyone else.
