What axis should the pipe be rotated about, X, Y, or Z when using AutoPIPE's Rotate command?
Depends on what one is trying to accomplish. Consider the following.
What axis to rotate about if pipe was rotated Clockwise in the Top isometric plane
Look at the model from the isoplane perspective, in this case Top view.
Questions: Which Global axis are your eyes looking? ( hint: Global axis X and Z form a plane perpendicular to this direction)
Answer: Correct, along the global Y-axis.
Recall from AutoPIPE training classes that AutoPIPE's Rotate command use Right hand rule where the thumb points in the direction of the respective axis.
With this knowledge it will be easy to understand that +ve rotation would be Counter(Anti)-Clockwise about the axis direction and conversely, -ve rotation would be Clockwise direction.
Let us see this in action:
Near the end of the movie, pipe was rotated about global Z-axis but appears not to have an affect on this model. Correct, because the pipe is modeled along that axis direction, the pipe is essentially rotating about the pipe axis with no graphical changes.
Question: If the pipe runs along X axis and slopes up vertically 45°: Would this be a “+” rotation along Z axis?
Answer: Yes. See Video below.
Question: If the pipe runs along the X axis and changes the direction 45° laterally in horizontal plan: would this be a “+” rotation about Y axis?
Answer: Yes. See Video below:
Question: Where in the menu would one find the Report showing the Component Rotation?
Answer: The Component Rotation report would be a temporary file with an *.ROT file extension that was saved to the same folder location as the model. Each time a Rotate command was completed with the "Show Rotation Report option enabled
it would display the new report overwriting the same *.ROT file again and again. There is no link to this file from the Menu or icons in the program.
