How to write to SIM_Data attributes

[ClausKleber]

Hi,

 

i am trying to write to some attributes from SIM_Data. How can i get a non-const GU_Detail? The attribute reference is always "read only".

Can someone give me an advice?

 

Here my code:

SIM_GeometryCopy *geo = SIM_DATA_CAST(obj.getNamedSubData(SIM_GEOMETRY_DATANAME), SIM_GeometryCopy);
if (geo)
{
    GU_DetailHandle gdh = geo->getGeometry().getWriteableCopy();
    const GU_Detail* gdp = gdh.peekDetail();
    GEO_AttributeHandle h = gdp->findPointAttribute("hittime");
    if (h.isAttributeValid())
    {
        for (GA_Iterator it(gdp->getPointRange()); !it.atEnd(); it.advance())
        {
            const GEO_Point *ppt = gdp->getGEOPoint(it.getOffset());
            h.setElement(ppt);
            h.setF(1.3f); // this has no effect
        }
    }
}
