PRC Table 59 PRC_TYPE_ASM_ProductOccurrence Location data type ill-defined #430

Open mvrhel opened 6 months ago

mvrhel commented 6 months ago

Describe the bug Table 59 describes the members of PRC_TYPE_ASM_ProductOccurrence . One optional bit of data is Location which is defined to have a Data Type of "Transformation" This type is not really defined in the spec, as there are several different types of "Transformations" Other areas of the spec have clarified the exact type of Transformation in the Data Description but this particular one provides no additional information.

It appears type should be 3D PRC_TYPE_MISC_GeneralTransformation (Array[16])

Does this refer to the general transformation (4x4 matrix) or any of the "named" ones talked about in 7.4.11 and table 87?

Also I am not sure I like the name "Location" for that row in table 60.

t3dr0 commented 1 week ago

I think this is the general one from 7.4.9 and not the subtypes in table 87. I also agree table 59(60) "Location" is not the best name. I propose to rename this to "transform", since the flag above it is "has_transform".
