I want to have analysis result, such as mass properties shown as a 3d annotation. Additionally I'd like to show a tubing bend table as a 3d annotation. This is because I'm trying to move away from 2d drawings and keep everything in 3d.
The first part is easy: You can use parameters in an annotation note. This can be a model parameter like &PRO_MP_MASS or a feature parameter, if you want to define your own mass properties analysis in an extra feature (e.g. MASS:FID_MASS_PROP_1, if the analysis feature is named MASS_PROP_1).
However, bend table information is not available like regular parameters as far as I know. They probably can be only loaded as text file into a note (no associativity).
