Hi Jan,
thanks for the help, your example works perfectly

Thanks so much

Hi Salvatore,

Unfortunately it's confusing a bit, because you mentioned cell (patterning), but demonstrate it using hatched (filled by lines) element.

When you do not want to hatch, why you care how to se hatch def lines? Especially when, by its name, this parameter seems to be valid for DWG data only.

It's expected behavior, because you do not update the element in DGN model.

It's not very complicated, using a combination of C++ documentation and some thinking how NET API is implemented (even though the code is a bit dirty):

// For a simplicity and testing purpose, element obtained using its ID
long elementId = 827;
using (Element element = Session.Instance.GetActiveDgnModel().FindElementById(new ElementId(ref elementId)))
{
    if (element is GroupedHoleElement gh)
    {
        using (AreaFillPropertiesEdit areFillProperties = gh.AsAreaFillPropertiesEdit())
        {
            Session.Instance.EnqueueKeyin("rc=areapat.cel");

            PatternParams pp = new PatternParams
            {
                CellName = "BATEN",
                Scale = 0.1
            };

            bool addWasSuccessful = areFillProperties.AddPattern(pp, null, 0);

            if (addWasSuccessful)
            {
                areFillProperties.ReplaceInModel(gh);
            }
        }
    }
}

Jan

Hi Jan,
yes of course there is a cell library attached,
about the image is just an example from the intended output.

What I would like to achieve is to add a pattern by repeatedly placing a cell.
Indeed in istruction
patternParams.CellName = "A0A";
I indicate the name of the model present in a cell library attached to the work design

What is not clear to me is how to correctly set the parameters of the patternParams and dwgHatchDefLine objects

Regards,

Salvio

I am not sure what does it mean "linked to working file".

When you want to use a cell for patterning, is the cell library attached?

From the picture and the code, it's not clear whether you want to add pattern (to place a cell repeatedly) or to hatch / crosshatch the grouped hole element.
