Back Yup, I see the distortion problem you mention now. As an extreme example, select a face on the cube and rotate it 80 degrees - you certainly do not have a cube with one face angled at 80 degrees - you have a chisel tip with very bad geometry!
I think your original idea of boolean subtracting a larger cube rotated to the same angle you want the face to be is the easiest solution.

Hi, Anthony,
Thanks for your reply. Well I have been working on the problem from a similar perspective as yours. Here is what I found. I have included a method which will be precise and exact using some of your info. The method should explain and resolve all the questions. 1 main problem I found was distortion following the angle change. It may be my card though nonetheless a problem to be resolved which it was.
Purpose: changing angle of one face of a cube to 22.5 degrees.
TS 6.6 tools used for this method are: 1): Use Navigation Control to effect a selected face angle change 2): Use PointEdit Control is checked and enabled
3): Use Object Info Panel for initial and final measurements 4): Isoparm handles : to readjust cubic dimensional alignment
Workspace Mode: PointEdit mode on the cube to get the face to change angle: Right Click the cube to invoke Point Edit Mode
Left Click the face to select it. This will bring into view the Isoparm outline
RightClick the cube face again to inact the PointEdit and Navigation controls
Depending on direction of face angle you wish use one of the navigation bars found on the navigation control (a three pronged webbed thingamajig) to effect the face angle change. I Used the green colored navigation bar while watching the Y rotational values found in the Object Info Panels reference of the cube I was working on.
Note: Direct angle change can be made using Anthonys suggestion here as well by entering the rotational angle value in the Object Info Panel.
Once the Y value = 22.50 degrees change I stopped.
Encountered Problems: Minor,a little cubic dimensional size distortion as noticed on cube following the initial angle change with the navigational (green) bar action to effect 22.5 degree change of the selected face. It was easily fixed using Object Info Panel references. The Point Edit rotate and move controls may be of some use here too as would be the Isoparm handles.
At this point I looked at the overall dimensions to checked for relative alignments of the cube and noticed that one line out of exact cubic dimensional form. With this I checked the size values and noticed they had changed slightly. Having made note of the size dimensions of the cube initially I reset them and then checked alignment again. Here double check that the angle of the face is not changed. I noticed too that after a few tries with an angle face change using this method I could pretty much get it right on the mark. With the face angel change set to 22.5 degrees and the cubic dimensions intact - away I went.
Thanks
David
