Tips and Tricks

[[Ju...]]

Something I have found useful in Calypso is using an hourglass scanning pattern for small planes. For some reason, this tends to produce better data. What are some other tips and tricks you've found useful for getting good results? (concentricity, perpendicularity, true position, etc.)

Thanks for sharing what works best for you.
When Calypso was first released, there were several documents created covering tips and tricks for about the first 5 to 12 versions.
However, there has been so many additions/changes in reporting and added capabilities, they have rendered a lot of the tip's and trick's obsolete.
There is some good info here:

I tend to follow how Calypso generates paths.
Circles are counter clockwise.
Cones are clock wise (I've had cases where Cones were the opposite. 🙄 )
Planes, are how ever Calypso generates a path. (Edit: when using Freeform)
My theory is the models for the behind the scenes math, are based on specified path generation, although the math can still be calculated in any direction.
In my studies, in particular Circles, I have found deviations of size and form when changing the default Calypso direction. (Minimal deviations).
Conventionally, the default for circular paths is Counter Clockwise, a negative rotation would be Clockwise.

Positive angle ranges for scan paths on circular features are always counter-clockwise. The reason it may look clockwise is the direction of the space axis. For example, an inverted cone with a -Z space axis will appear to be scanning clockwise but if you do the right thumb rule where your right thumb points in the space axis direction, the curl direction of your fingers is counter-clockwise and a positive direction.

Also, for circles and cylinders, the space axis defaults to a positive direction, +X, +Y or +Z. Cones, the space axis goes from the small end of the cone to the large end.

Can I ask, which year Calypso first released?

Not to cut into your conversation but I believe it was 1996. If you look at the version info, it states 1996-2xxx
