If you are trying to see PMI type annotations, unfortunately those are not yet supported in the PiXYZ PLUGIN for Unity.
As of now, only PiXYZ STUDIO and PiXYZ REVIEW can display PMIs, and there is no way yet to convert PMIs annotation in something that can be viewed in Unity :
I tried this option but still it's not importing the annotation. The formats i used are .stp, .3dxml.
The source CAD object is from CATIA. Also we changed the export settings for step in CATIA to Application protocal to 242 and 214. in this format the exported file will have all colour data, PMI data, etc. But i see these are not importing using PiXYZ. Or is there any other way to do it.
In addition, When i import, i see the model tree to be cut short than what it is in CATIA.So my inference is that, I beleive PiXYZ is filtering the data and this is the reason the PMI Data and Annotation colour data are not coming into Unity.
Correct me if am wrong and help me if all these can be done in PiXYZ and how to do it.
If it is not natively doable, can it be done by PiXYZ scripting?
PïXYZ natively reads most 3D annotation types on a wide range of formats. In the PiXYZ PLUGIN for Unity, there is an import setting to enable the import of such data (converted as polylines to fit in Unity's meshes).
This option is named "Import Lines" and is one of the parameters in the Import section of the Import Window.
Let me know if it worked for you.
