Model Metadata in X3d #13

Open merco opened 10 months ago

merco commented 10 months ago

It would be possibile to have metadata (GENERAL_PROPERTY) in X3D?

Could STP2X3D generate a separate file output with these information ?

here the file http://davidemercanti.altervista.org/sources/1M001934.stp

It might be possible to get those information from the STEP file. For now, we do not have plans to officially include the function to export a separate file for those information. Please refer to the source codes related to STEP file import which will give you a hint how to get those information. I'll be happy to answer your follow-up questions.

Thank you. I've built source code with VS2019.
However, it is not clear to me which OCC object to use to read the GENERAL_PROPERTY associated with a component. Can you help me with some example links?

Consider using "StepBasic_GeneralProperty". See "STEP_Data.cpp" for traversing STEP instances.

Here's an example of getting id, name, and description of an instance of a general property.

include

... ... Handle(StepBasic_GeneralProperty) gp = Handle(StepBasic_GeneralProperty)::DownCast(entity); string id = gp->Id()->ToCString(); string name = gp->Name()->ToCString(); string desc = gp->Description()->ToCString();

Thank you. Ok I can get the names traversing entities... but It is not clear to me how to recover the value of the property and know which instance it is connected to
