Currently I am trying to create .skp files from some external geometry data.
I have managed to create all required geometries, but after i save model by using following code:
if (SUModelSaveToFileWithVersion(model, model_path, SUModelVersion::SUModelVersion_SU2018) != SU_ERROR_NONE){
return 0;
}
if (SUModelRelease(&model) != SU_ERROR_NONE){
return 0;
}
SUTerminate();
model is saved without small preview icon(general .skp icon is used).
Is there a way to replace it with at least a white icon?
This would be a bug in the API when saving. I'm afraid there is not workaround for that via the C API. (Btw, you can report issues in the SketchUp API issue tracker: https://github.com/SketchUp/api-issue-tracker/issues)
