I create a 3D Box for the user to adjust to define a volume in a 3D model. I use SendComand so that the box has a full set of grips (AddBox does not reveal stretch grips).
ARX does not expose 3d Solid Normal, Position, Length, Width or Height, so to obtain the new box dimensions and location after user adjustment I tried adding points to the corners of the box in extended data using DXF type 1011 - World Space Coordinates.
If the user uses grips to stretch or move the box the extended data points are not updated. This problem will affect any app using extended data where the user can use grips to adjust an object.
My solution was to list the Box to the command line then capture the command line history to extract the values I needed. - not very elegant but it does the job!
