Forums:
The code I copied from http://www.nxjournaling.com/content/creating-bounding-box-arround-solid is very good but it is accurate when applied to the displayed part only. In the assembly mode, it is not accurate as it does not create box around the correct directions.In other words, the box dimensions reported in displayed-part mode and assembly mode are not the same. How should the code be adjusted so the dimensions in assembly mode is the same as the displayed part mode?
