This new software version looks like it got rid of the solid layers infill pattern rotation angles. Has this been taken out or has it been changed in a different menu location? please help

For example: I used to be able to have the solid infill rectilinear pattern switch direction every layer in any specific order. This helped close small holes left from the infill to the outline, without having to increase flow rate or outline overlap

layer 1: 0 degrees
layer 2: 90 degrees
layer 3: -45 degrees
layer 4: 45 degrees
layer 5: 0 degrees
layer6: 90 degrees
layer 6: -45 degrees
layer 8: 45 degrees

There's still the "Internal Pattern Rotation" angle setting on the Edit Process Settings > Infill tab. That rotates the entire pattern, so if you selected something like rectilinear, you could easily get -45/+45 or 0/90 degrees.

I'm not sure I understood what you said about "closing small holes left from the infill to the outline". Can you post a photo explaining that more? That would make it easier to give suggestions.

I agree - I wish this feature was brought back.

We used it to create added rigidity in areas of printed parts that needs to solid, long and thin. being being able to control the direction the plastic is being laid down, helps in that regards.

interestingly enough, the settings are still honored if you open a *.factory file that was created in a previous version of S3D that still had that feature. When you slice it, the patterns that where defined will show up in the slice, but not way to edit it. if you change any setting in that area, it removes to previous honored slice behavior.

This gets you there to some degree, but does lack the nuance that being able to explicitly define the angles gets you. For instance, say you have a part that is orientated at a 45 degree angle on the the print bed and you need/want the first layer to lay done lengthwise to that ornamentation (45deg) of the first layer matches the length of the part. But then you want to rotate the infill patterns for subsequent layers by 10 or 15 degrees, ending with the last layer again, ornamented in the 45 degree angle -

I think @3dgaragehack is suggesting that by being able to control the angles of the infill pattern , it give them the ability to create a more solid (water tight) surface without having to widen (increase flow) of the extrusion for those areas. Again, a valid use of such a feature.
