hatch style in a block

[lulu]

Hi,
I have an AutoCAD that contains some blocks (insert). Is it possible to act on the single elements that compose the block?
Particularly, I need to modify the style of an hatch.

Thank you,
lulu.

Hello.
Entities within the block can be accessed as insert's block entities. For example

Code: Select all

CADImage image;
CADInsert insert;
CADHatch hatch;

// .......

    (((CADEntity)image.Converter.Entities[i]).EntType == EntityType.Insert)
    {
        insert = (CADInsert)image.Converter.Entities[i];
        if (((CADEntity)insert.Block.Entities[j]).EntType == EntityType.Hatch)
        {
            hatch = (CADHatch)insert.Block.Entities[j];
            hatch.HatchStyle = CADHatchStyle.Solid;
        }
    }

will access style of the hatch object if insert placed with i index in converter's entities collection and hatch placed with j index in block's entities collection.

Hi Alexander,
thank you for your reply, but I have another problem now. The type of the hatches (inside the blocks) in the AutoCAD file results 'CurvePolygon', and I don't understand why it happens... How can I convert a CADCurvePolygon in a CADHatch?

Thanks,
lulu.

Hello lulu,
CADCurvePolygon object can't be cast to CADHatch object. However CADHatch is the descendant of CADCurvePolygon. You can create new Hatch object, fill its properties by corresponded values from CurvePolygon and specify HatchStyle.
